It comes in a through-hole TO-220-2 package (PG-TO220-2-1). Its 140 ns reverse recovery time places it inside the fast-recovery class (trr ≤ 500 ns), making it a candidate for hard-switched PFC boost stages, flyback secondary rectification, and DC-link freewheeling in motor drives or UPS inverters where recovery losses at turn-off matter. ## Forward drop and switching loss trade-off Forward voltage is 2.15 V at 9 A. The 140 ns trr reduces reverse-recovery charge compared to a 500 ns part. ## Leakage and temperature range Reverse leakage is 100 µA at 1200 V. ## Active lifecycle, no obsolescence concern No NRND or last-time-buy notice is on record. It is ROHS3 compliant.","metaTitle":"IDP09E120XKSA1 Fast Recovery Diode, 1.2 kV 23 A TO-220-2","metaDescription":"IDP09E120XKSA1 standard fast recovery diode, 1200 V reverse voltage, 23 A average rectified current, 140 ns trr, TO-220-2 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Package":"Bulk","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-2","lifecycle_stage":"eol_hot","Supplier Device Package":"PG-TO220-2-1","Reverse Recovery Time (trr)":"140 ns","Current - Reverse Leakage @ Vr":"100 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"23A","Operating Temperature - Junction":"-55°C ~ 150°C","Voltage - Forward (Vf) (Max) @ If":"2.15 V @ 9 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.77","priceTiers":[{"qty":388,"price":"$0.77000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/33227905efaa1f4a1054be93c2b63804.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IDP09E120XKSA1/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of IDP09E120XKSA1?","answer":"The reverse recovery time (trr) is 140 ns, which qualifies it as a fast recovery diode per the ≤ 500 ns class definition."},{"question":"What are the specifications of IDP09E120XKSA1?","answer":"It is a 1200 V, 23 A average rectified current fast recovery diode in a TO-220-2 through-hole package.
