DB107 is a 1A 1000V single-phase bridge rectifier mainly used to convert AC power to DC power, commonly found in low-power power supply circuits. Its core parameters are 1A current and 1000V withstand voltage, and it adopts plug-in packaging

Model differentiation: DB107 is a plug-in type. If the suffix has "S" (such as DB107S), it is a surface mount package, and the parameters are basically the same

DB107 plays a crucial role as a rectifier bridge in DC power supply circuits. It can convert alternating current into direct current, ensuring the correct flow of current. If the power supply is reversed, it may damage other components in the circuit. DB107 can avoid this situation and protect the circuit from damage.

For some simple circuit designs, DB107 not only plays a role in preventing reverse connections, but also simplifies circuit wiring. Connecting the power cord directly to the corresponding port of DB107 can reduce the number of external connections and improve the reliability and safety of the circuit.

It should be noted that although DB107 can prevent reverse connections, it cannot be completely relied upon. In practical applications, other protective measures such as overcurrent protection and overvoltage protection should be combined to ensure the safety and reliability of the circuit. Reasonably configuring these protective measures can ensure stable operation of the circuit under various conditions.

Overall, DB107 plays an important role in DC power supply circuits, not only in preventing reverse connections, but also in simplifying circuit design and improving overall circuit performance.

Application scenarios: Widely used in small household appliances, switch mode power supplies, LED smart lighting fixtures, mobile phone chargers, power adapters and other low-power devices

After full wave rectification, the 50Hz AC voltage is converted into a pulsating DC voltage u1, and then the DC high voltage U1 is obtained through the input filtering capacitor. Ideally, the conduction angle of the rectifier bridge DB207 should be 180 ° (with a conduction range of 0 ° to 180 °), but due to the effect of the filtering capacitor C, it can only approach the AC peak voltage for a short period of time before the input current flows through the rectifier bridge to charge C. The half cycle of 50Hz AC power is 10ms, the conduction time of the rectifier bridge is iC ≈ 3ms, and its conduction angle is only 54 ° (conduction range is 36 °~90%). Therefore, the rectifier bridge DB207 actually passes narrow pulse current.

The primary conduction process of a rectifier diode can be regarded as a "gate pulse", with a pulse repetition frequency equal to the frequency of the AC power grid (50Hz)

In order to reduce the conduction noise below 500kHz in switching power supplies, sometimes two ordinary silicon rectifiers and two fast recovery diodes are used to form a rectifier bridge.

Parameter selection of rectifier bridge DB207

The isolated switch mode power supply uses a rectifier bridge composed of rectifier tubes, or can directly use a finished rectifier bridge to complete bridge rectification. The full wave bridge rectifier DB207 is called a silicon rectifier bridge, which is a semiconductor device made by connecting four silicon rectifier tubes into a bridge circuit and then encapsulating it with plastic. DB207 has the advantages of small size, easy use, and good consistency of various rectifier parameters, and can be widely used in the rectifier circuit of switching power supplies. The silicon rectifier bridge DB207 has four terminals, including two AC input terminals and two DC output terminals.

The average maximum rectified current of silicon rectifier bridge is divided into various specifications such as 0.5~40A, and the maximum reverse operating voltage is divided into various specifications such as 50~1000V. The low-power silicon rectifier bridge DB207 can be directly soldered.

Connected to the printed circuit board, large and medium power silicon rectifier bridges need to be fixed with screws and installed with suitable heat sinks.

Recently, due to the continuous increase in raw materials, labor costs have also been rising.

Our diode and rectifier bridge products have endured a long period of no profit.

Based on market conditions, our company will adjust the product prices. Different types of products have different price increases.

Please confirm with our company before placing an order and confirm the latest price again.

Our company will optimize costs in all aspects and provide customers with the most competitive prices.

The SM4007 rectifier diode MELF is a very classic rectifier diode. Let's start by looking at some of its key specifications.

• Average Rectified Forward Current: 1A

• Reverse Voltage Rating: 1000V

What is a MELF package?

MELF, short for Metal Electrode Leadless Face, is the most distinctive feature of the SM4007 rectifier diode.

Appearance: Unlike traditional SMA surface-mount diodes, which have a flat rectangular package, the SM4007 comes in a small cylindrical glass body with metal end caps on both sides.

How do you identify the polarity?

A colored band is marked around the cylindrical body. The end closest to the band is the cathode.

Advantages of the MELF package

• Excellent heat dissipation and power density

• Extremely low leakage current

• High surge-current capability and reliability

Disadvantages of the MELF package

Prone to rolling during SMT assembly and reflow processes

Usage Note

The SM4007 rectifier diode is a standard-recovery rectifier diode. It is not suitable for high-frequency switching power supplies or applications that require fast recovery performance. For such applications, fast-recovery or Schottky diodes are generally preferred.

If you are looking to buy SM4007 online, make sure to choose components from reputable manufacturers and authorized distributors to ensure product quality and reliability.

1. Maximum rectified current (IF): Similar to HER508, HER308 also has its maximum rectified current limit. Normally, the maximum rectified current of HER308 is 3A.

This means that in circuit design, it is necessary to ensure that the current passing through HER308 does not exceed this limit.

2. Maximum reverse voltage (VR): The maximum reverse voltage of HER308 is also one of its important parameters. Generally speaking, the maximum reverse voltage that HER308 can withstand is 800V.

In practical applications, it is necessary to ensure that the reverse voltage applied to both ends of HER308 does not exceed this value to avoid breakdown.

3. Forward voltage drop (VF): The forward voltage drop of HER308 is also affected by the passing current.

Under normal operating conditions, the forward voltage drop of HER308 will remain at a relatively low level, which helps to improve the overall efficiency of the circuit.
