The forward voltage is 860 mV at the full 2 A load — a typical Schottky drop that keeps conduction losses manageable in a low-voltage rail. The junction temperature rating of 175°C maximum gives thermal headroom for designs that run hot, such as in cramped power supplies or industrial enclosures. The reverse leakage is 1 µA at 100 V — low enough that it won't load down a high-impedance node in standby or OR-ing applications. ## Switching speed classification The part carries a Fast Recovery classification: =< 500 ns recovery time at > 200 mA forward current. While Schottky diodes are inherently majority-carrier devices with negligible stored charge, this speed rating confirms it is characterized for switching applications — not just line-frequency rectification. It fits in a 100 kHz to low-MHz SMPS output stage or as a freewheeling diode in a DC-DC converter. ## Through-hole DO-41 package — retrofit and repair fit The STPS2H100RL comes in a DO-204AL (DO-41) axial-lead through-hole package. This is a legacy footprint that is still common in industrial power supplies, appliance control boards, and automotive aftermarket modules where through-hole assembly is preferred for manual rework or high-vibration environments. The DO-41 body is 2.6 mm diameter with 25.4 mm lead spacing typical — the same footprint as a 1N400x series diode, so it drops into existing PCB layouts without a board spin.","metaTitle":"STPS2H100RL Schottky Rectifier, 100 V 2 A, DO-41, Obsolete","metaDescription":"STPS2H100RL Schottky rectifier: 100 V reverse, 2 A average, 860 mV forward drop, DO-41 through-hole.","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":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"DO-204AL, DO-41, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS2H100","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-41","Current - Reverse Leakage @ Vr":"1 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"860 mV @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/18dc6a838a9c8dbf1207de088a2c607f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS2H100RL/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS2H100RL?","answer":"No official replacement order code is listed by STMicroelectronics. For a drop-in functional replacement, look for a 100 V, 2 A Schottky rectifier in a DO-41 package with similar forward voltage and leakage specs. The STPS2H100RL is a standard Schottky; many manufacturers offer compatible parts.
