3 variants · WeEn Semiconductors
The WeEn Semiconductors BYV34 Series series groups 3 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. The listed variants share a common case of TO-220-3, current - average rectified (Io) (per diode) of 20A and diode configuration of 1 Pair Common Cathode. Variants differ by current - reverse leakage @ vr, operating temperature - junction and voltage - DC reverse (Vr), so you can match the exact current - reverse leakage @ vr your application requires using the selection guide below.
| Parameter | BYV34-400,127 | BYV34-500,127 |
|---|---|---|
| Current - reverse leakage @ vr | 50 µA @ 400 V | 50 µA @ 500 V |
| Operating temperature - junction | - | 150°C(Max) |
| Voltage - DC reverse (Vr) | 400 V | 500 V |
