ABSF15M

Bridge Rectifier Overview

The ABSF15M is a surface-mount single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for fast recovery applications. It features an average forward current rating of 1.5 A and supports peak forward surge currents up to 50 A at 50 Hz or 55 A at 60 Hz. The device operates with a maximum repetitive reverse voltage (VRRM) of 1000 V, ensuring robust performance in high-voltage environments. Electrical characteristics include a forward voltage drop below 1.3 V at 0.8 A and a leakage current under 2 µA at 25°C. The junction-to-ambient thermal resistance is less than 80 K/W on standard pads and 62 K/W on larger copper areas. Operating temperatures range from -50°C to +150°C.
