The fast recovery characteristic (≤ 500 ns, > 200 mA) suits continuous-conduction-mode topologies where reverse-recovery losses matter. STMicroelectronics has placed the STPS40M100CR into Last Buy status. This is the final procurement window before production ceases. For a drop-in replacement, evaluate the STPS40M100CT (TO-220) or STPS40M100CG (D²PAK) – same die, different package – but verify the pinout and thermal pad compatibility against your existing I2PAK footprint. ## Conduction losses and thermal design At 20 A per diode the typical forward drop is 780 mV, yielding about 15.6 W conduction loss per diode at full rated current – the I2PAK tab must be heatsinked to keep junction temperature below the 150 °C maximum. Reverse leakage is 70 µA at 100 V, 25 °C – expect this to rise with junction temperature, so account for standby losses in high-temperature environments.","metaTitle":"STPS40M100CR Schottky Diode Array, 100V 20A, I2PAK, Last Buy","metaDescription":"STPS40M100CR dual Schottky rectifier, 100V, 20A per diode, 780mV Vf, I2PAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Last Buy","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":"Last Time Buy","lifecycle_stage":"eol_hot","Base Product Number":"STPS40","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"I2PAK","Current - Reverse Leakage @ Vr":"70 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"780 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7100","priceTiers":[{"qty":1,"price":"$2.49000","currency":"USD"},{"qty":10,"price":"$2.23400","currency":"USD"},{"qty":100,"price":"$1.79590","currency":"USD"},{"qty":500,"price":"$1.47552","currency":"USD"},{"qty":1000,"price":"$1.37900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/808d770364b8428be6520b49e81d8741.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS40M100CR/alternatives.json"},"ai":{"faq":[{"question":"Is the STPS40M100CR obsolete?","answer":"The STPS40M100CR is in Last Buy status – the manufacturer has announced end of production.
