Littelfuse IXYS DSEP29-12A Fast Recovery Diode with Low Leakage Current and Avalanche Voltage Rating
DSEP29-12A Low Loss and Soft Recovery High Performance Fast Recovery Diode
Product Overview
The DSEP29-12A 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. Its very low Irm-values and soft reverse recovery contribute to reduced power dissipation and lower turn-on losses in commutating switches, minimizing EMI/RFI. The diode is avalanche voltage rated for reliable operation and is suitable as an antiparallel diode for high-frequency switching devices, antisaturation diode, snubber diode, and freewheeling diode. It is also used in rectifiers for switch mode power supplies (SMPS) and uninterruptible power supplies (UPS).
