STMicroelectronics – Diodes “RQ” 600V Extension to 60A – STH60RQ06(-Y)

Rapid and Quiet reverse Recovery 600V diodes boost all resonant converters

ST now offers 600V “RQ” new dides (Rapid & Quiet), developed for on-board battery chargers (OBC), 2 or3 wheelers chargers, EV charging stations, and industial converters. These diodes Feature a specific Vrrm guaranteed from -40°C to +175°C, a unique trade-off a soft reverse recovery -to reduce EMI, and a low VF,-to gain effeciency in all modes of resonant based topologies. Ranging now from 15A up to 60A Forward current ratings, ST’s STTH15RQ06(Y), STTH30RQ06(Y), and STTH60RQ06(Y), are avaible in surface – mount (D²PAK), and through – hole (TO- 220AC and DO-247) packages, in both Industrial grade and automotive grade AEC-Q101 qualified.
