The 175°C junction rating gives headroom in compact, surface-mount layouts that run hot. At 3 A forward current, the maximum forward voltage is 755 mV — this sets the conduction loss floor. At 100 V reverse, the leakage current is 5.7 µA, a figure that rises with junction temperature. The 175°C Tj max allows the diode to run at higher ambient temperatures without derating, but the leakage increase at elevated Tj must be factored into the thermal budget. In a 3 A output rail, the Vf × If product is about 2.3 W at full load; the SOD-128 flat package's thermal resistance to the board copper determines whether that heat can be sunk without exceeding the junction limit. ## Package and rework — SOD-128 flat profile The SOD-128 flat package (also called SOD128Flat) is a surface-mount, leadless design with a low profile. The flat leads sit flush against the PCB pad, which helps with solder wetting and visual inspection after reflow. For rework, the package has low thermal mass — a hot-air station at 300–350°C with a fine nozzle lifts it cleanly without cooking adjacent parts. For BOM planning, the active status means no near-term LTB risk, but the part should be qualified for new designs with the usual supply-chain monitoring.","metaTitle":"ST STPST3H100AF Schottky Diode, 100V 3A, SOD-128","metaDescription":"STPST3H100AF Schottky rectifier, 100 V reverse, 3 A forward, 755 mV Vf at 3 A, 5.7 µA leakage, 175°C Tj, SOD-128 flat package.","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":"ECOPACK®2","Package":"Tape & Reel (TR)","Technology":"Schottky","Mounting Type":"Surface Mount","Package / Case":"SOD-128","Product Status":"Active","lifecycle_stage":"eol_hot","Capacitance @ Vr, F":"-","Supplier Device Package":"SOD128Flat","Current - Reverse Leakage @ Vr":"5.7 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"175°C","Voltage - Forward (Vf) (Max) @ If":"755 mV @ 3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1393","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/370d858fc02bf1b9fb83f38413297a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPST3H100AF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STPST3H100AF?","answer":"No official cross-reference or second-source alternate is documented for this part.
