With a 2.5 µs reverse recovery time, it is a line-frequency rectifier — suited for mains input bridges, PFC boost stages, and DC bus pre-charge circuits where switching speed is not the constraint. ## 2.5 µs trr — standard recovery, not fast switching The 2.5 µs reverse recovery time places this diode in the standard-recovery class (>500 ns). It handles 50/60 Hz rectification cleanly but will not work in a 100 kHz+ PFC or LLC converter where a fast or ultrafast diode (trr < 100 ns) is required. The 60 pF junction capacitance at 4 V is consistent with a slow-recovery die. ## Junction temperature range and package The DO-214AB (SMC) package provides a large cathode tab for heat sinking to the PCB copper plane; the 1.15 V forward drop at 2.5 A sets the conduction loss budget for thermal design. ## Active production and compliance It is ROHS3 compliant, which satisfies EU and most global regulatory requirements without exemptions.","metaTitle":"S3K-E3/9AT Vishay Standard Recovery Rectifier, 800 V, 3 A","metaDescription":"Vishay S3K-E3/9AT standard recovery rectifier diode, 800 V reverse voltage, 3 A average current, 2.5 µs trr, DO-214AB SMC package.
