That trr puts it in the class of diodes used for snubber clamping in flyback converters, freewheeling in low-power motor drives, and as a bootstrap diode in half-bridge gate drivers. The DO-214AC (SMA) package keeps the footprint small enough for dense PSU layouts. ## Forward drop and leakage — thermal budget factors Maximum forward voltage is 940 mV at 1 A, and reverse leakage is 3 µA at the full 200 V reverse rating. The leakage figure matters at elevated junction temperatures — it rises exponentially with temperature and can eat into the standby power budget in a lightly loaded offline supply.","metaTitle":"STPR120A Fast Recovery Diode, 200V 1A 35ns trr, DO-214AC SMA","metaDescription":"STMicroelectronics STPR120A fast recovery rectifier, 200V 1A, 35ns trr, DO-214AC SMA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR)","Technology":"Standard","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPR120","Capacitance @ Vr, F":"-","Supplier Device Package":"SMA (DO-214AC)","Reverse Recovery Time (trr)":"35 ns","Current - Reverse Leakage @ Vr":"3 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"940 mV @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1091","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ddc74d824f6d66a074f465b7d27a88ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPR120A/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STPR120A?","answer":"The STPR120A is obsolete from STMicroelectronics but is available through independent distribution.
