SFR101 – SFR107 is a soft fast recovery rectifier produced by Won-Top Electronics. It features low forward voltage drop, high current, high reliability, and high surge current capability.
The SFR101‑SFR107 series are 1.0 A soft fast recovery rectifiers with low forward voltage drop, high current capability, and high surge current capability. Features include a diffused junction, high reliability, and a molded‑plastic case with plated leads.
Mechanical data, maximum ratings, and electrical characteristics are listed, along with operating and storage temperature ranges, weight, and ordering options. The document also contains notes on derating for capacitive loads and warranty statements.
| Peak Repetitive Reverse Voltage (VRRM) | 50‑1000 V (model dependent) |
|---|---|
| Average Rectified Output Current (Io) | 1.0 A |
| Forward Voltage at 1.0 A (VFM) | 1.2 V |
| Operating Temperature Range | -65 °C to +125 °C |
| Weight | 0.34 g (approx.) |
For capacitive loads, the current should be derated by 20 %.
SFR101 is offered in a DO‑41 package with T3 (tape & reel), TB (ammo pack), or standard box configurations.
The forward voltage at 1 A is 1.2 V.
The SFR104 model has a peak repetitive reverse voltage rating of 400 V.
