Diode and Rectifier Devices

Overview

Microsemi is a pioneer in creating Rectifier Diodes, since 1960. Its current Diode offering includes high power diodes, RF Diodes and virtually every variety of Diode used in Space, Commercial Aviation, Hi-Reliability, Military and Industrial (including Automotive) applications. Microsemi’s discrete solutions are qualified to MIL-PRF-19500, and the company has more DLA slash sheet qualifications than any other manufacturer of space level. We were the first diode manufacturer selected by the U.S. military services as a source of supply to qualify product to the highest specified reliability level.

For Commercial / Industrial applications, covering a wide range of application requirements, Microsemi diode offerings include DL series with low VF and ultra-soft recovery, medium speed and voltage D series, high speed ultrafast recovery DQ series, very high speed DS series, and silicon Schottky S series diodes. Ultrafast recovery (DQ) diode products in particular are suited for higher switching frequency applications like AC-DC/DC-DC converters in H/EV chargers and switch mode power supply applications. The DQ diode family comes in 600 V, 1000 V, and 1200 V series and current ratings from 8 A up to 100 A. AEC-Q101 qualification for high voltage DQ diode family extends product penetration into higher reliability applications like onboard chargers and powertrain.
