1 kV peak reverse — why the voltage class matters
The VS-2KBB100 is a single-phase bridge rectifier rated for a peak reverse voltage of 1 kV. That places it in the high-voltage class — suitable for rectifying 240 VAC mains or higher, with enough margin for line transients and surge events common in industrial power supplies and motor drives.
1.9 A average current — derating for real loads
The average rectified current is 1.9 A, with a forward voltage drop of 1.1 V at that current. At full load, the conduction loss is about 2.1 W — the 4-SIP through-hole package relies on the PCB copper and airflow to keep the junction below the 150°C maximum. For continuous operation above 1 A, a heatsink or forced air should be considered.
Through-hole 4-SIP — footprint and assembly
Housed in a 4-SIP, 2KBB package, the VS-2KBB100 is a through-hole device. The four pins are on 0.100-inch pitch, and the body is compact enough for dense board layouts. Through-hole mounting gives a robust mechanical anchor for high-vibration environments like industrial drives and automotive under-hood applications.
It is ROHS3 compliant.
