Product Description
Product Overview
The DSEP2x91-06A is a high-performance fast recovery diode featuring low loss and soft recovery characteristics. Designed with planar passivated chips, it offers very low leakage current and extremely short recovery times, contributing to improved thermal behavior and reduced power dissipation. Its soft reverse recovery minimizes EMI/RFI, and avalanche voltage rating ensures reliable operation. This diode is ideal as an antiparallel diode for high-frequency switching devices, antisaturation diode, snubber diode, and free-wheeling diode, as well as in rectifiers for switch mode power supplies (SMPS) and uninterruptible power supplies (UPS).
