Littelfuse IXYS DSEI2X101-12A Fast Recovery Diode Optimized for Snubber and Antiparallel Applications
Product Overview
The DSEI2x101-12A is a Fast Recovery Epitaxial Diode featuring parallel legs with low loss and soft recovery characteristics. Designed for high-frequency switching applications, it offers a very short recovery time, improved thermal behavior, and very low reverse recovery current (Irm) values. Its soft reverse recovery minimizes EMI/RFI and reduces power dissipation and turn-on losses in commutating switches. 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).
