Fast high-voltage soft-recovery controlled avalanche rectifiers BY9300 series
The BY9300 series from Philips Semiconductors are fast, high‑voltage, soft‑recovery controlled avalanche rectifiers. They feature a plastic package with glass passivation, high maximum operating temperature, low leakage current, and very low reverse recovery time, making them suitable for colour television, monitors, and high‑voltage multiplier applications.
The datasheet lists detailed electrical limits, such as peak reverse voltages up to 25 kV, storage temperature from –65 °C to +175 °C, and forward voltage values ranging from 10 V to 44 V at 10 mA. Graphs illustrate permissible forward current versus ambient temperature and forward voltage versus junction temperature.
| Storage temperature range | -65 °C to +175 °C |
|---|---|
| Forward voltage at 10 mA (BY9304) | 10 V |
| Reverse current (typical) | 3 nA |
The series is rated for storage temperatures from –65 °C up to +175 °C.
At 10 mA, the BY9304 forward voltage is 10 V.
They are intended for colour television and monitors up to 32 kHz, as well as high‑voltage multiplier and diode‑split‑transformer applications.
