The 870 mV forward drop at 30 A keeps conduction losses manageable for a 30 A device, and the 45 µA reverse leakage at 100 V is typical for a Schottky of this voltage and current class. STMicroelectronics no longer manufactures this part in its original form. For a BOM line that specifies this exact order code, procurement must go through surplus, broker, or independent distribution channels. The 100 V reverse voltage rating gives headroom for 48 V and 72 V bus rails with typical derating for transients. The 870 mV forward drop at 30 A means about 26 W conduction loss at full load, which drives the heatsink sizing. The 45 µA leakage at 100 V doubles roughly every 10 °C above 25 °C junction, so at 125 °C junction the leakage can approach several milliamps — factor that into standby power budgets for hot environments. The Fast Recovery =< 500 ns classification is typical for a Schottky; the lack of stored charge means it switches faster than a PN diode, which matters for the switching losses in a 50–100 kHz converter.","metaTitle":"STPS30SM100SR Schottky Rectifier, 100V 30A TO-262","metaDescription":"STPS30SM100SR Schottky diode: 100V reverse voltage, 30A average current, 870mV forward drop at 30A.","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","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-262-3 Long Leads, I²Pak, TO-262AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS30","Capacitance @ Vr, F":"-","Supplier Device Package":"I2PAK","Current - Reverse Leakage @ Vr":"45 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"30A","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"870 mV @ 30 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/be3f4152a2d61df0715366ad11cea430.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS30SM100SR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS30SM100SR?","answer":"For a pin-compatible replacement, look at the STPS30SM100S series in the same TO-262 package — verify the forward voltage and leakage specs against your design margin.
