Stabilized diodes and fast recovery diodes
The voltage stabilizer diode is made of the voltage stabilizer performance shown by the reverse breakdown characteristics of PN junction, also known as Zener diode or reverse breakdown diode, which plays a role of voltage stabilizer in the circuit. It uses diode reverse breakdown, in a certain range of reverse current, the reverse voltage does not change with the reverse current characteristics to stabilize the voltage.
Generally made of silicon semiconductor materials by alloy or diffusion process. It not only has the characteristics of common diode single guide, but also can work in reverse breakdown state. At present, the low temperature coefficient of the regulator is composed of two regulator reverse series. Good temperature compensation can be obtained by using the positive and negative temperature coefficients of two regulator tubes working in positive and negative direction.
Fast diodes include fast recovery diodes and Schottky diodes, which are mainly used in high frequency rectifier circuit, high frequency switching power supply, high frequency resistance and capacitance absorption circuit, inverter circuit and so on.
Fast diode reverse recovery time up to 10ns, it is a semiconductor diode with good switching characteristics and short reverse recovery time. Mainly used in switching power supply, PWM pulse width modulator, inverter and other electronic circuits. Used as high frequency rectifier diode, continuant diode or damping diode.
Schott base tubes are based on a barrier layer formed by metal contact with a semiconductor. Its main characteristics are small forward guide voltage drop (about 0.45V), short reverse recovery time, small switching loss. It is a low power consumption, ultra-high speed semiconductor device, widely used in switching power supply, inverter, driver and other circuits. It can be used as high frequency, low voltage, high current rectifier diode, continuous diode and protection diode, or in microwave communication circuit as rectifier diode, small signal detection diode.
