Each diode is rated for 60 V reverse voltage and delivers an average rectified current of 20 A, with a maximum forward voltage of 595 mV at that current. The fast recovery time — under 500 ns — qualifies it for switching power supplies and high-frequency rectification stages where standard PN-junction diodes would incur excessive switching losses. ## Common-cathode pair in a through-hole power tab The common-cathode configuration means the two anodes are separate pins while the shared cathode connects to the package tab — a layout that suits center-tap full-wave rectifiers or OR-ing diode stages in redundant power feeds. The TO-262 (I2PAK) through-hole package with long leads is designed for bolted-down thermal management: the tab carries the cathode and can be screwed to a heatsink, while the leads solder into the board. Maximum junction temperature is 150°C, so the thermal path from tab to ambient must keep the die below that ceiling at full 20 A per diode. ## Reverse leakage and the 60 V rail At the 60 V maximum reverse voltage, reverse leakage is specified at 110 µA. Leakage increases with junction temperature toward 150°C — a factor to budget for in high-ambient enclosures.","metaTitle":"STPS40M60CR Schottky Rectifier, 60V 20A Dual Common Cathode","metaDescription":"STPS40M60CR 60V 20A per diode Schottky rectifier, dual common cathode in TO-262 I2PAK.","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","Technology":"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":"110 µA @ 60 V","Voltage - DC Reverse (Vr) (Max)":"60 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"595 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a12e6ce2e6e01e0d588d457fafda8d4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS40M60CR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS40M60CR obsolete?","answer":"Yes, STMicroelectronics has listed the STPS40M60CR as obsolete.
