S1MF SMAF 1A 1kV General Purpose Diode – Ultra-Fast Rectifier

Product Description:
The S1MF SMAF 1A 1kV General Purpose Diode is a high-voltage, high-reliability rectifier designed for a wide range of power conversion and protection applications. With a 1A forward current rating and 1000V (1kV) reverse voltage, this diode is ideal for AC-DC rectification, chargers, adapters, LED drivers, relay protection circuits, and industrial power supplies.

Its compact SMAF (DO-219AB) ultra-thin SMD package offers excellent thermal performance, reduced footprint, and enhanced switching efficiency. The S1MF provides stable and efficient rectification with low forward voltage drop and reliable high-temperature operation, making it suitable for compact, high-density PCB designs.
