Product Description
Product Overview
The DSEP30-12A is a high-performance fast recovery diode featuring low loss and soft recovery characteristics. It is designed with planar passivated chips, offering very low leakage current, very short recovery time, and improved thermal behavior. Its very low Irm-values and soft reverse recovery contribute to reduced power dissipation and lower turn-on losses in commutating switches, making it ideal for applications requiring low EMI/RFI. This diode is suitable 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).
