What the headline ratings mean for your rectifier stage
The V20PW22C-M3/I is a dual common-cathode Schottky rectifier rated 10 A average per diode (20 A total package) with a 200 V maximum reverse voltage. Forward drop is 930 mV maximum at 10 A per diode. That 175 °C Tj max is the AEC-Q101 Grade 0 ceiling, meaning it survives under-hood soak temperatures without derating the current.
Automotive qualification and package fit
For a production BOM that requires a PPAP-ready device, the V20PW22C-M3/I carries the traceable lot acceptance data — no commercial-grade waiver needed. The exposed drain tab on the bottom is the common cathode — the PCB layout must connect it to the output rail with a thermal via array under the tab to pull heat into the inner layer.
