This datasheet describes the SANYO DBF250, a silicon‑diffused junction, single‑phase bridge rectifier. It lists the device’s features, absolute maximum ratings, electrical characteristics, and mechanical dimensions, and includes safety and export‑control notices.
Key specifications include a peak reverse voltage of 200 V (DBF250C) or 600 V (DBF250G), an average rectified current of 25 A with a heatsink (3.5 A without), a surge forward current rating of 350 A for a 50 Hz sine wave, and thermal resistance values of 22 °C/W (junction‑ambient) and 1 °C/W (junction‑case).
| Peak Reverse Voltage | 200 V (DBF250C) / 600 V (DBF250G) |
|---|---|
| Average Rectified Current (with heatsink) | 25 A |
| Average Rectified Current (without heatsink) | 3.5 A |
| Surge Forward Current | 350 A (50 Hz sine, 1‑cycle peak) |
| Forward Voltage at 12.5 A | 1.05 V |
| Reverse Current | 10 µA |
| Thermal Resistance (J‑A, no heatsink) | 22 °C/W |
| Thermal Resistance (J‑C, with heatsink) | 1 °C/W |
| Maximum Junction Temperature | 150 °C |
| Storage Temperature Range | -40 °C to +150 °C |
The DBF250C version is rated for 200 V and the DBF250G version for 600 V peak reverse voltage.
With a heatsink, the DBF250 can handle an average rectified current of 25 A.
The device can tolerate a surge forward current of 350 A for a 50 Hz sine wave one‑cycle peak.
Thermal resistance is 22 °C/W junction‑ambient without a heatsink and 1 °C/W junction‑case with a heatsink.
