S1A/B–S1M/B Vishay Lite–On Power Semiconductor is a surface mount glass passivated rectifier with the following features: low forward voltage drop and high current capability, surge overload rating to 30A peak, ideally suited for automated assembly, plastic material – UL recognized flammability classification 94V–0.
The S1A/B–S1M/B series are surface‑mount glass‑passivated rectifiers designed for automated assembly and high‑current capability. Key features include low forward voltage drop, surge overload rating up to 30 A peak, and UL‑recognized flammability classification.
The datasheet lists absolute maximum ratings such as a 50 V repetitive peak reverse voltage and 100 V DC blocking voltage, electrical characteristics like 1.1 V forward voltage at 1 A, 5 µA reverse current at 25 °C, and a thermal resistance of 50 K/W. Dimensions, mounting options, and a statement confirming the devices contain no ozone‑depleting substances are also included.
| Repetitive peak reverse voltage (VRRM) | 50 V |
|---|---|
| Peak forward surge current (IFSM) | 30 A |
| Forward voltage at 1 A (VF) | 1.1 V |
The repetitive peak reverse voltage is 50 V.
The device can handle a peak forward surge current of 30 A.
The forward voltage is 1.1 V at a forward current of 1 A.
No, Vishay certifies that the semiconductors are not manufactured with ozone‑depleting substances.
