Its forward voltage is specified at 570 mV at the full 16 A load — that's the number to use when estimating conduction loss in a high-current OR-ing or output rectifier stage. STMicroelectronics lists the STPS1645D as obsolete. ## Fast recovery spec — what it means The listing notes Fast Recovery =< 500 ns, > 200 mA (Io). It is not intended for high-frequency SMPS applications where a 50 ns or faster recovery is needed.","metaTitle":"STPS1645D Schottky Diode, 16 A, 45 V, TO-220AC","metaDescription":"STPS1645D Schottky rectifier: 16 A average, 45 V reverse, 570 mV forward drop at 16 A, TO-220AC.","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-220-2","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS1645","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC","Current - Reverse Leakage @ Vr":"200 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Current - Average Rectified (Io)":"16A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"570 mV @ 16 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c65d58e6cb9135e80571d254aa7fb283.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS1645D/alternatives.json"},"ai":{"faq":[{"question":"Can I use STPS1645D in a 12V circuit?","answer":"Yes. With a 45 V reverse voltage rating, the STPS1645D has ample margin for 12 V rails, including automotive 12 V systems that see load-dump transients. The 16 A average current covers most high-current OR-ing, battery isolation, and output rectifier stages in that voltage class."},{"question":"What is the STPS1645D cross reference?","answer":"For a pin-compatible replacement in a new design, evaluate active 45 V, 16 A Schottky rectifiers in TO-220AC from ST or other manufacturers — verify the forward voltage and thermal performance against your load profile."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS1645D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS1645D when reusing this data.
