Function of SUNMATE Schott diode — SUNMATE

Function of SUNMATE Schott diode

Also known as Schottky barrier diode, it is a low-power, ultra-high speed semiconductor device. The most remarkable feature is that the reverse recovery time is very short (as small as a few nanoseconds), and the forward conduction voltage drop is only about 0.4V. The biggest feature of Schottky diode is that the forward voltage drop VF is relatively small. Under the same current, its forward voltage drop is much smaller. In addition, its recovery time is short. It also has some disadvantages: low withstand voltage and large leakage current. It is mostly used as high-frequency, low-voltage and high current rectifier diode (such as switching power supply secondary rectifier diode), freewheeling diode and protection diode. It is also used as rectifier diode and small signal detection diode in microwave communication and other circuits. It is common in communication power supply, frequency converter, etc.

Comprehensive consideration shall be given to the selection.

Schottky diode is a low-power, ultra-high-speed semiconductor device, which is widely used in switching power supply, frequency converter, driver and other circuits. It is used as high-frequency, low-voltage, high current rectifier diode, freewheeling diode and protection diode, or as rectifier diode and small signal detection diode in microwave communication and other circuits. Common applications: power supply, charger, adapter. Automotive electronics. Small household appliances, etc.
