BYT12PI-1000RG

Overview

The BYT12PI-1000 is a fast recovery rectifier diode manufactured by STMicroelectronics, designed for high-voltage and high-frequency applications. It features a repetitive peak reverse voltage of 1000 V and an average forward current rating of 12 A at a case temperature of 50°C. The device exhibits a very low reverse recovery time of 155 ns under standard test conditions, contributing to minimal switching losses and low noise during turn-off. Electrical insulation is provided via an isolated TO-220AC plastic package with a capacitance of 7 pF and an insulating voltage of 2500 VRMS. Thermal resistance from junction to case is rated at 4 °C/W.
