STMicroelectronics lists the STPS8L30B as Obsolete. For existing BOM lines, supply runs through independent distribution and surplus inventory. ## Forward drop and leakage — the Schottky trade-off The 490 mV Vf at 8 A is low for an 8 A Schottky, which keeps junction temperature rise in check during continuous conduction. The trade-off shows up in reverse leakage: 1 mA at the 30 V rated reverse voltage. That leakage doubles with temperature, so standby power budgets in hot environments (85°C+ ambient) need to account for it. For OR-ing diodes where leakage matters less than forward efficiency, this part pulls ahead of a PN-junction rectifier. For ultra-low-leakage requirements, a higher-Vf Schottky or a FET-based ideal diode would be a better fit.","metaTitle":"STPS8L30B Schottky Rectifier, 8 A, 30 V, DPAK, Obsolete","metaDescription":"STPS8L30B Schottky rectifier: 8 A average, 30 V reverse, 490 mV Vf at 8 A, DPAK surface mount.","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","Technology":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS8L","Capacitance @ Vr, F":"-","Supplier Device Package":"DPAK","Current - Reverse Leakage @ Vr":"1 mA @ 30 V","Voltage - DC Reverse (Vr) (Max)":"30 V","Current - Average Rectified (Io)":"8A","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"490 mV @ 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/324ca415f17c2a1e1404becce2174f66.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS8L30B/alternatives.json"},"ai":{"faq":[{"question":"Is STPS8L30B obsolete?","answer":"Yes, STMicroelectronics lists the STPS8L30B as Obsolete.
