No further production runs are scheduled. For new builds or repairs, source through the surplus and broker channel. We can quote against an RFQ from our independent distribution network. The 780 mV forward voltage at 10 A is typical for a 80 V Schottky at this current — expect about 7.8 W conduction loss per diode at full load, which the I2PAK through-hole package handles with a proper heatsink. Housed in a TO-262 (I2PAK) through-hole package with long leads. The I2PAK is the isolated-tab variant of TO-220 — the metal tab is electrically isolated, so no insulating pad is needed between the tab and the heatsink. Mount with the tab screw to a heatsink for any continuous load above a few amps.","metaTitle":"STPS20SM80CR Schottky diode, 80 V 10 A dual common cathode","metaDescription":"STPS20SM80CR dual Schottky rectifier, 80 V reverse voltage, 10 A per diode, 780 mV forward drop at 10 A.","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":"STPS20","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"I2PAK","Current - Reverse Leakage @ Vr":"25 µA @ 80 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"780 mV @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/18cd64187c7ca89048d42980ddc77e02.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20SM80CR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS20SM80CR obsolete?","answer":"Yes, STPS20SM80CR is listed as obsolete.
