It is a standard-recovery Schottky diode, not a fast-recovery type — the 'Fast Recovery =< 500ns' spec line is a catalog classification for rectifiers above 200 mA, not a switching-speed claim. The part is intended for low-to-medium power rectification, freewheeling, and polarity protection in power supplies, adapters, and DC-DC converters where the 2 A average current and 100 V blocking voltage fit the rail. At 2 A forward current the maximum forward voltage is 860 mV. That is a typical figure for a 100 V Schottky in this current class — higher than a 40 V Schottky, but necessary for the 100 V blocking capability. The reverse leakage is specified at 1 µA at 100 V, which is low for a Schottky and helps keep standby losses down. The junction temperature ceiling of 175°C gives headroom in hot environments, but the leakage current rises exponentially with temperature, so the thermal design should account for the leakage at the operating junction temperature, not just at 25°C. ## DO-41 axial — rework-friendly but layout matters The DO-41 axial package is a through-hole part with leads that bend to fit the board. It is easy to hand-solder and rework — a hot-air station or soldering iron lifts it without trouble, and the cathode band is clearly marked on the body. The trade-off is board space: the axial body and bent leads take up more area than a surface-mount equivalent, and the lead diameter needs a plated through-hole with adequate annular ring. For new designs, a surface-mount Schottky in SMA or SMB might save space, but for repair, retrofit, or low-volume builds the DO-41 is a practical choice.","metaTitle":"STPS2H100 Schottky Diode, 100V 2A DO-41, Active","metaDescription":"STPS2H100 Schottky diode, 100V reverse voltage, 2A average rectified current, DO-41 axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Cut Tape (CT) Tape & Box (TB)","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"DO-204AL, DO-41, Axial","Product Status":"Active","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":"$0.6700","priceTiers":[{"qty":1,"price":"$0.67000","currency":"USD"},{"qty":10,"price":"$0.58400","currency":"USD"},{"qty":100,"price":"$0.40410","currency":"USD"},{"qty":500,"price":"$0.33760","currency":"USD"},{"qty":1000,"price":"$0.28732","currency":"USD"},{"qty":2000,"price":"$0.25590","currency":"USD"},{"qty":6000,"price":"$0.24243","currency":"USD"},{"qty":10000,"price":"$0.22447","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/18dc6a838a9c8dbf1207de088a2c607f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS2H100/alternatives.json"},"ai":{"faq":[{"question":"Can STPS2H100 replace 1N5819?","answer":"The 1N5819 is a 40 V, 1 A Schottky in a DO-41 package. The STPS2H100 is a 100 V, 2 A part — it has higher voltage and current ratings. In a circuit originally designed for the 1N5819, the STPS2H100 will physically fit the same DO-41 footprint, but the higher forward voltage (860 mV vs roughly 600 mV for the 1N5819 at 1 A) will increase conduction loss, and the higher reverse voltage rating is not a problem. Check the forward voltage drop at your operating current and the thermal budget before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS2H100","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS2H100 when reusing this data.
