The pair shares a cathode, so it handles center-tap or push-pull secondary windings with one package. Junction temperature is rated up to 175°C, which gives thermal headroom in cramped power stages. ## Forward drop and leakage — the trade-off at 150 V At 10 A forward current the maximum forward voltage is 920 mV — typical for a 150 V Schottky, where the blocking voltage pushes Vf up compared to lower-voltage parts. Reverse leakage is specified at 5 µA at 150 V, which is tight for a Schottky at that voltage; it keeps stand-by losses low in OR-ing or reverse-protection circuits. The common-cathode layout means the two anodes are separate, so each diode can be paralleled for higher current or used independently on different rails. ## D²Pak package — thermal and mounting notes The STPS20150CG comes in a TO-263-3 (D²Pak) surface-mount package with an exposed tab. No lab bench needed for a swap, but the tab orientation is obvious from the package outline; just make sure the pad is big enough to sink the 20 A total if both diodes run hard. The tube shipping is fine for rework stations, though for production you would want the tape-and-reel variant. That means no new factory orders; the only channel is surplus or broker stock. The STPS20150CG is still a valid replacement for field repair or BOM fill while stock lasts.","metaTitle":"STPS20150CG Schottky Diode, 150 V 10 A, D²Pak, Obsolete","metaDescription":"STPS20150CG is a 150 V, 10 A per diode Schottky rectifier in a common-cathode D²Pak.

The closest current-production alternative would be a 150 V, 10 A per diode common-cathode Schottky in D²Pak — for example, the STPS20150CT is a through-hole TO-220 variant, not pin-compatible. Check the STPS20H100CG or similar dual-Schottky families for a surface-mount fit, but verify pinout and thermal pad layout against your board."},{"question":"Where can I buy STPS20150CG?","answer":"Submit an RFQ and we will confirm current availability and pricing at quote time — no stock or price figures on this page."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20150CG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20150CG when reusing this data.
