Its AEC-Q101 qualification and 175°C maximum junction temperature make it suited for automotive under-hood environments such as alternator rectification, DC-DC converter output stages, and reverse-battery protection. The low forward voltage of 840 mV at 25 A helps keep conduction losses manageable in high-current paths. The 45 V reverse voltage gives headroom for 12 V and 24 V automotive rails, including load-dump transients that can push a nominal 12 V bus above 40 V. The 175°C junction rating means the die can handle the self-heating from 25 A forward current plus ambient under-hood heat without derating — a key spec for alternator or motor-drive rectifier bridges where the diode sees both high current and a hot environment.","metaTitle":"STPS2545CGY-TR Schottky Diode, 45V 25A, AEC-Q101, D2PAK","metaDescription":"STPS2545CGY-TR automotive Schottky rectifier: 45V reverse voltage, 25A average rectified current (12.5A per diode), 840mV forward drop at 25A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR)","Technology":"Schottky","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS2545","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D2PAK","Current - Reverse Leakage @ Vr":"125 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"840 mV @ 25 A","Current - Average Rectified (Io) (per Diode)":"12.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0094","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/561d41f495127ea907ce8ec0f4a46a3a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS2545CGY-TR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS2545CGY-TR a direct replacement for STPS2545CT?","answer":"The STPS2545CGY-TR is the automotive-grade (AEC-Q101) variant of the STPS2545CT, qualified to the same electrical ratings but with the extended temperature range and qualification required for automotive applications.
