The forward drop is specified at 745 mV at 15 A, which directly sets the conduction loss in high-current OR-ing, flyback, or boost stages. ## Fast recovery and leakage — switching and standby trade-offs Listed as a fast-recovery Schottky (≤ 500 ns), this diode handles switching frequencies typical of 50–100 kHz PFC and DC-DC converters without excessive reverse-recovery loss. Reverse leakage is 40 µA at 80 V, a figure to factor into standby-power budgets in always-on supplies.","metaTitle":"STPS30M80CT Schottky Diode, 80 V, 15 A, TO-220-3","metaDescription":"STPS30M80CT dual common-cathode Schottky rectifier: 80 V, 15 A per diode, 745 mV Vf, 175°C Tjmax.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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-220-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS30","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"40 µA @ 80 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"745 mV @ 15 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9032","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/689604191b88752b8d947296e0b71ab7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS30M80CT/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum junction temperature of STPS30M80CT?","answer":"The maximum junction temperature is 175°C, which allows operation in high-temperature environments such as enclosed power supplies and motor drives."},{"question":"What is the difference between STPS30M80CT and STPS30L80CT?","answer":"The STPS30L80CT is a lower forward-voltage variant (typically 630 mV at 15 A) compared to the STPS30M80CT's 745 mV at 15 A. The trade-off is higher reverse leakage in the L80CT, so the M80CT is preferred where lower standby current matters at elevated temperatures."},{"question":"Is STPS30M80CT RoHS compliant?","answer":"The STPS30M80CT is listed as RoHS compliant per STMicroelectronics' standard lead-free plating for TO-220 packages.
