Application:

Overvoltage protection circuit in TV:
115V is the main power supply voltage of the TV. When the output voltage of the power supply is too high, D is turned on, and the transistor T is turned on. The collector potential will change from the original high level (5V) to the low level, and the voltage through the standby control line. Put the TV into standby protection.

Arc suppression circuit:
When a suitable Zener diode is connected in parallel on the inductor coil (or the same principle as a normal diode), when the coil is turned off, the high voltage generated by the release of electromagnetic energy is used by the diode. Absorbed, so when the switch is turned off, the arc of the switch is eliminated. This application circuit is used more in the industry, such as some higher power electromagnetic control circuits.

The bridge rectifier is to seal the rectifier in a shell. Divided into full bridge and half bridge. The full bridge seals the four diodes of the connected bridge rectifier circuit. The half bridge is to seal together half of the two diode bridge rectifiers. Two bridges can be used to form a bridge rectifier circuit. One half bridge can also form a full-wave rectifier circuit with a center tap of the transformer. Rectifier circuit and working voltage

The function of MB10S bridge rectifier is to work through the diode's unidirectional conduction principle. In general, the diode is forward-conducting and reverse-cut, that is, the diode only allows its positive pole to be positive and negative pole to be negative. The diode only allows the current to pass in one direction, so when it is connected to the AC circuit, it can make the current in the circuit flow only in one direction, so-called "rectification", with two tubes being half-pumped rectification, and four tubes being full-flow rectification.

Convert AC power to DC power, including half-wave rectification, full-wave rectification, and bridge rectification. The bridge rectifier encapsulates the four diodes of the bridge rectification and draws only four pins. Of the four pins, two DC outputs are labeled + or -, and the two AC inputs have a ~ mark. Apply the rectifier bridge to the circuit, mainly considering its maximum operating current and maximum reverse voltage.

Fast recovery diodes are also commonly used as graphical symbols for common diodes, either by text or by model. The fast recovery diode is similar to a normal diode, but the manufacturing process is different from that of a normal one. The doping concentration near the PN junction is very low, resulting in a higher switching speed and a lower forward voltage drop.
Compared with Schottky diodes, the withstand voltage is much higher. It is mainly used as a high-speed rectifying component, which is used as a rectifying transistor in switching power supplies and inverter power supplies to reduce turn-off loss, improve efficiency and reduce noise.
