P6SMB440CA

BORN · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

P6SMB440CA from BORN, in a SMB(DO-214AA). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Bidirectional TVS terminal (P6SMB440CA, polarity-independent) with 376 V reverse stand-off, 418-462 V breakdown at 1 mA, and 602 V maximum clamping at 1 A peak pulse current.
2 A2 passive Second bidirectional TVS terminal, interchangeable with the other terminal, for 600 W peak pulse power (10/1000us) and 376 V stand-off in either polarity.
