Product Description
Product Overview
The DSEP60-12A 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, very short recovery times, and improved thermal behavior with very low Irm-values. Its soft reverse recovery minimizes EMI/RFI, and the avalanche voltage rating ensures reliable operation. Applications include antiparallel diodes for high-frequency switching devices, antisaturation diodes, snubber diodes, free-wheeling diodes, and rectifiers in switch-mode power supplies (SMPS) and uninterruptible power supplies (UPS).
