With a 30 ns trr, it handles the turn-off switching losses in a 100 kHz boost converter or a flyback snubber without the stored charge penalty of a standard recovery diode — the recovery is soft enough to keep EMI below the radiated limit in a MIL-STD-461 test. The 3 A average rating is continuous; the forward surge capability at 9.4 A (2.04 Vf) means it survives the inrush from a capacitive load or a motor start without exceeding the junction's 155°C ceiling. ## Package and thermal integration The D-5A (SQ-MELF, A case) is a hermetic surface-mount package with a metallized ceramic body and solderable end caps — no plastic encapsulation, no moisture sensitivity level to track, and no popcorn cracking risk during reflow. The junction runs from -65°C to 155°C, which covers the full military temperature range plus margin for self-heating in a 3 A continuous load. The SQ-MELF footprint is non-standard compared to a DO-214 or SMB — the solder pad geometry and stencil aperture should follow Microchip's application note for the D-5A package to avoid tombstoning or voiding under the end caps.","metaTitle":"Microchip 1N6074US Fast Recovery Diode, 100V 3A D-5A","metaDescription":"1N6074US fast recovery rectifier diode from Microchip Technology. 30 ns trr, 100 V reverse, 3 A average, D-5A SQ-MELF package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Microchip Technology","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Bulk","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"SQ-MELF, A","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"1N6074","Capacitance @ Vr, F":"-","Supplier Device Package":"D-5A","Reverse Recovery Time (trr)":"30 ns","Current - Reverse Leakage @ Vr":"1 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"-65°C~155°C","Voltage - Forward (Vf) (Max) @ If":"2.04 V @ 9.4 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.7700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/12268cf719b5a07dc12bb6da8ee3311a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6074US/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of the 1N6074US?","answer":"The 1N6074US has a 30 ns reverse recovery time (trr), classifying it as a Fast Recovery diode (≤500 ns, >200 mA Io).
