Its 58 ns reverse recovery time (trr) keeps switching losses low in hard-switched topologies like boost PFC stages, output rectifiers in welding inverters, and IGBT snubber clamp circuits. ## Switching loss and thermal budget At 100 A forward current the maximum forward voltage drop is 3.6 V, giving a conduction loss floor of 360 W per diode at full load — the heatsink must handle that plus the switching loss from the 58 ns trr. Reverse leakage at 1200 V is 75 µA, negligible at 25 °C but rising with junction temperature; the datasheet's thermal derating curve sets the safe operating area for continuous 110 A DC per diode. ## Package and mounting — SOT-227 miniBLOC The SOT-227-4 (miniBLOC) package is a chassis-mount module with screw terminals for the anode and cathode connections and a metal baseplate for direct heatsink attachment. Two independent diodes in one module let you build the high-side and low-side of a half-bridge leg without separate discrete parts, saving board space and bus-bar routing. No official successor or pin-compatible second source is listed on the record; for dual-sourcing resilience, confirm the BOM position and compare the thermal and switching characteristics of other 1200 V, 110 A-class fast-recovery modules in SOT-227.","metaTitle":"VS-HFA220FA120 HEXFRED® Fast Recovery Diode Module, 1200 V","metaDescription":"VS-HFA220FA120 HEXFRED® fast recovery diode module, 1200 V, 110 A per diode, 58 ns trr, SOT-227-4.","metaKeywords":null},"attributes":{"series":"HEXFRED®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"HEXFRED®","Package":"Tube","Technology":"Standard","Mounting Type":"Chassis Mount","Package / Case":"SOT-227-4, miniBLOC","lifecycle_stage":"eol_hot","Diode Configuration":"2 Independent","Supplier Device Package":"SOT-227","Reverse Recovery Time (trr)":"58 ns","Current - Reverse Leakage @ Vr":"75 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Voltage - Forward (Vf) (Max) @ If":"3.6 V @ 100 A","Current - Average Rectified (Io) (per Diode)":"110A (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$55.87","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$55.87000","currency":"USD"},{"qty":10,"price":"$50.78800","currency":"USD"},{"qty":100,"price":"$45.70920","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0d898eaa34accbf67fdfd956edb22bfc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of the VS-HFA220FA120?","answer":"The reverse recovery time (trr) is 58 ns, placing it in the fast-recovery class (≤ 500 ns at > 200 mA).
