DHG 20 I 600 PA
preliminary
VRRM = IFAV = t rr =
600 V 20 A 40 ns
Backside: cathode
Features / Advantages:
● Planar passivated chips ● Very low leakage current ● Very short recovery time ● Improved thermal behaviour ● Very low Irm-values ● Very soft recovery behaviour ● Avalanche voltage rated for reliable
operation ● Soft reverse recovery for low EMI/RFI ● Low Irm reduces:
- Power dissipation within the diode - Turn-on loss in the commutating switch
Applications:
● Antiparallel diode for high frequency switching devices
● Antisaturation diode ● Snubber diode ● Free wheeling diode ● Rectifiers in switch mode power
supplies (SMPS) ● Uninterruptible power supplies (UPS)
Package:
● Housing: TO-220
●rIndustry standard outline ●rEpoxy meets UL 94V-0 ●rRoHS compliant
