The 725 mV forward drop at 1 A is typical for a 100 V Schottky at this current density; expect the drop to rise with temperature, so budget conduction loss accordingly in the thermal calculation. ## Leakage and switching — the no-recovery-time claim Reverse leakage is 1.7 µA at 100 V, which is low for a 100 V Schottky and keeps standby drain negligible in always-powered automotive modules. The 'No Recovery Time > 500 mA' speed rating means this diode exhibits negligible reverse-recovery charge — it switches off essentially instantaneously, which matters in high-frequency DC-DC converters where recovery losses would otherwise dominate. ## SOD-123F — small footprint, thermal care needed The SOD-123F package is a surface-mount, low-profile body roughly 2.6 mm × 1.6 mm. At 1 A continuous, the copper pad area on the PCB sets the junction-to-ambient thermal resistance — a minimal land pattern will push junction temperature toward the 175°C limit under full load. For designs running near 1 A, a flooded cathode pad with thermal vias to an inner-layer plane is recommended.","metaTitle":"STPST1H100ZFY Automotive Schottky Diode, 100 V, 1 A","metaDescription":"STPST1H100ZFY automotive Schottky diode, 100 V reverse, 1 A forward, 725 mV Vf, 175°C junction, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"No Recovery Time > 500mA (Io)","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"SOD-123F","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPST1","Capacitance @ Vr, F":"-","Supplier Device Package":"SOD-123F","Current - Reverse Leakage @ Vr":"1.7 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"725 mV @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3600","priceTiers":[{"qty":1,"price":"$0.36000","currency":"USD"},{"qty":10,"price":"$0.27600","currency":"USD"},{"qty":100,"price":"$0.16550","currency":"USD"},{"qty":500,"price":"$0.15326","currency":"USD"},{"qty":1000,"price":"$0.10422","currency":"USD"},{"qty":3000,"price":"$0.09595","currency":"USD"},{"qty":6000,"price":"$0.09196","currency":"USD"},{"qty":9000,"price":"$0.08276","currency":"USD"},{"qty":30000,"price":"$0.08154","currency":"USD"},{"qty":75000,"price":"$0.07663","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8c859aa20b0a79b6fd5b9b8e064e158d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPST1H100ZFY/alternatives.json"},"ai":{"faq":[{"question":"Is STPST1H100ZFY AEC-Q101 qualified?","answer":"Yes, the STPST1H100ZFY is AEC-Q101 qualified, which is the stress-test qualification standard for automotive-grade discrete semiconductors.
