800 V, 30 A — the rectifier for 48 V and 400 V automotive bus stages
The STBR3008WY is a standard recovery power diode rated for 800 V reverse voltage and 30 A average forward current, housed in a DO-247 through-hole package. It is part of the STMicroelectronics Automotive series and carries AEC-Q101 qualification, meaning it is tested and released for automotive stress profiles — thermal cycling, high-temperature reverse bias, and extended junction temperature operation.
175 °C junction — designed for under-hood thermal cycles
The 2 µA reverse leakage at 800 V is specified at 25 °C; expect leakage to rise exponentially with temperature, so the thermal design should budget for higher standing losses at sustained 150 °C junction.
Standard recovery — not for fast switching
Recovery time is classified Standard Recovery (>500 ns, >200 mA). This is a line-frequency or low-speed freewheeling diode — do not use it in a high-frequency converter where reverse recovery losses would dominate.
Lifecycle status is Active. No end-of-life notice, no last-time-buy schedule. The DO-247 package is a standard through-hole power package, widely tooled.
