Its key parametric strength is a forward voltage of 450 mV at the full 2 A rated current, which directly reduces conduction losses in the power path. ## 450 mV forward drop — what it buys the BOM At 2 A forward current the STPS2L30A drops 450 mV, a typical figure for a 30 V Schottky in this current class. That translates to about 0.9 W of conduction loss at full rated current — manageable in the SMA package with reasonable copper area, but worth derating if ambient runs above 85 °C. The 200 µA reverse leakage at 30 V is the other side of the Schottky trade-off: low Vf comes at the cost of higher leakage than a fast-recovery pn diode, so the designer should check standby dissipation in high-temperature, lightly loaded conditions. ## Fast recovery ≤ 500 ns — switching fit The Schottky barrier eliminates stored charge, so recovery is essentially capacitive — the 500 ns bound covers the RC tail rather than a minority-carrier reverse recovery. For flyback or boost converters running above 500 kHz, a lower-Qrr Schottky (e.g., 100 V rated) may be a better fit, but for 30 V rails this part is a solid, cost-effective choice. ## Active, no LTB risk For dual-sourcing resilience, the SMA footprint is widely used across the 2 A Schottky class; a pin-compatible alternative such as the SS24 shares the same DO-214AC outline and similar ratings, though the forward drop and leakage specs differ slightly — verify the Vf curve against your thermal budget before substituting.","metaTitle":"STPS2L30A Schottky Diode, 2A 30V SMA, 450mV Vf","metaDescription":"STPS2L30A Schottky rectifier, 2A average, 30V reverse, 450mV forward drop at 2A in DO-214AC SMA.","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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS2L30","Capacitance @ Vr, F":"-","Supplier Device Package":"SMA","Current - Reverse Leakage @ Vr":"200 µA @ 30 V","Voltage - DC Reverse (Vr) (Max)":"30 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"450 mV @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f98e30172d759737e630c993822c1903.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS2L30A/alternatives.json"},"ai":{"faq":[{"question":"Is STPS2L30A equivalent to SS24?","answer":"The SS24 is a common 2 A, 40 V Schottky in the same DO-214AC (SMA) package, so it is a footprint-compatible alternative.
