In a TO-262 (I2PAK) through-hole package, the junction temperature is rated to 175 °C maximum, so the thermal path through the tab and heatsink must keep the junction below that ceiling under full load. ## Reverse leakage at temperature Reverse leakage is specified at 65 µA at 80 V. Schottky leakage rises exponentially with junction temperature; at 175 °C the actual leakage will be significantly higher, which must be factored into standby-power and thermal-runaway calculations. ## Lifecycle — obsolete, sourced to order STMicroelectronics lists the STPS40M80CR as obsolete.","metaTitle":"STPS40M80CR Schottky Diode, 80 V, 20 A, Fast Recovery","metaDescription":"STPS40M80CR dual common-cathode Schottky rectifier: 80 V, 20 A per diode, 735 mV Vf, fast recovery ≤500 ns.","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":"Tube","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-262-3 Long Leads, I²Pak, TO-262AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS40","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"I2PAK","Current - Reverse Leakage @ Vr":"65 µA @ 80 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"735 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f69372d2ec41fbefa283db16d743d0dc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS40M80CR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS40M80CR?","answer":"No official replacement part number is recorded in the lifecycle data.
