Its 50 ns reverse recovery time (trr) places it in the fast-recovery class for continuous-current-mode (CCM) power factor correction (PFC) boost stages, hard-switched SMPS output rectifiers, and 400 VDC bus freewheeling paths where a standard 1N5408-class part would overheat from reverse-recovery losses. ## Forward drop and thermal budget at 15 A At the full 15 A rated current the maximum forward voltage is 2.95 V, which translates to roughly 44 W of conduction loss. That figure drives the heatsink requirement — a D2PAK on a standard FR-4 board with 1 oz copper needs a thermal pad area of at least 600 mm² on the drain tab to keep the junction below 175°C at full load in still air. ## Package and mounting — D2PAK footprint notes The D2PAK (TO-263AB) is a three-lead surface-mount package with a large exposed copper tab on the bottom. The tab is the anode connection and the primary thermal path. A reflow profile with a peak temperature of 260°C per JEDEC MSL Level 1 is standard. The footprint requires a minimum copper pad on the tab of 9.4 mm × 10.2 mm to carry the current and spread the heat; a solder-paste stencil aperture covering 70–80 % of the tab area prevents voids. The two cathode leads are on a 2.54 mm pitch. It is ROHS3 compliant and part of the ECOPACK® series, meaning the mould compound and plating are free of halogens and antimony trioxide per ST's green packaging standard. No official second-source or pin-compatible cross-reference is listed in the ST portfolio — the base product number STTH15 covers the 600 V, 15 A family, and the RQ06G suffix denotes the 50 ns trr grade in D2PAK.","metaTitle":"STTH15RQ06G-TR Diode, 600V 15A Fast Recovery 50ns D2PAK","metaDescription":"STMicroelectronics STTH15RQ06G-TR general purpose fast recovery diode, 600V 15A, 50ns trr, D2PAK surface mount.
