The VS-KBPC8005 is a Vishay single-phase bridge rectifier from the VS-KBPC8 series, built with standard silicon technology in a through-hole D-72 package. It rectifies AC to DC in power supplies where the peak reverse voltage stays under 50 V and the average load current does not exceed 8 A. Rated 50 V peak reverse (VRRM) and 8 A average rectified output (Io), this part fits low-voltage DC bus applications — think 24–48 VAC transformer secondaries feeding a bulk capacitor. The 1 V forward drop at 3 A (Vf) means conduction loss is about 3 W at that current, so the D-72 case needs some airflow or a heatsink tab if you run near the 8 A ceiling.
It is RoHS non-compliant (lead-bearing termination finish), so confirm your assembly house accepts tin-lead solder before committing the BOM line. Supplied in bulk tube — no reel or tape packaging, which simplifies hand-placement in low-volume builds but means pick-and-place lines need a tube feeder or tray.
