What are the typical types of rectifier diodes?

rectifier diodes are semiconductor devices that use the unidirectional characteristics of PN junctions to turn alternating current into pulsating direct current. When selecting a rectifier diode, parameters such as maximum rectifier current, maximum reverse working current, cutoff frequency and reverse recovery time should be considered.

rectifier diodes have different reverse recovery times depending on the chip process, and are usually divided into four categories:

1. Ordinary rectifier diode, reverse recovery time is greater than 500nS

2. Fast recovery rectifier diode, reverse recovery time 150-500nS

3. High efficiency rectifier diode, reverse recovery time 50-100nS

4. Ultra-fast rectifier diodes, reverse recovery time 15-35nS
