The BYD31 series is a fast soft-recovery controlled avalanche rectifier, featuring glass passivation, high maximum operating temperature, low leakage current, excellent stability, and guaranteed avalanche energy absorption capability.
The Philips BYD31 series are fast soft‑recovery controlled avalanche rectifiers offered in a glass‑passivated cylindrical package. The data sheet provides detailed electrical characteristics, limiting values, and thermal parameters for each voltage rating within the series.
Key sections cover features, limiting values, thermal resistance, graphical performance curves, and application notes, with a clear statement that these devices are not recommended for new designs.
| Repetitive peak reverse voltage (BYD31D) | 200 V |
|---|---|
| Repetitive peak reverse voltage (BYD31K) | 800 V |
| Continuous reverse voltage (BYD31M) | 1000 V |
| Storage temperature range | -65 °C to +175 °C |
The BYD31K can withstand a repetitive peak reverse voltage of 800 V.
No, the data sheet states they are not recommended for new designs.
