Durable Littelfuse IXYS DHG30I1200HA Sonic Fast Recovery Diode Suitable for High Frequency Switching
Product Overview
The DHG 30 I 1200 HA is a high-performance Sonic Fast Recovery Diode designed for demanding applications. It features low loss and soft recovery characteristics, making it suitable as an antiparallel diode for high-frequency switching devices, antisaturation diode, snubber diode, and free-wheeling diode. This single diode in a TO-247 package offers very low leakage current, very short recovery time, improved thermal behavior, and very low Irm-values with soft reverse recovery for reduced EMI/RFI. Its avalanche voltage rating ensures reliable operation, and the low Irm minimizes power dissipation within the diode and turn-on losses in commutating switches. Applications include rectifiers in switch mode power supplies (SMPS) and uninterruptible power supplies (UPS).
