P6SMB480A

Littelfuse · TVS · DO-214AA(SMBJ)

P6SMB480A from Littelfuse, in a DO-214AA(SMBJ). 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 Cathode passive Cathode terminal of the unidirectional TVS, marked by the color band on the package; P6SMB480A has VR 408 V, VBR 456-504 V at 1 mA and maximum VC 658 V at 1.3 A.
2 Anode passive Anode terminal of the unidirectional TVS, opposite the cathode band; the device is rated 800 W peak pulse power (stacked-die part) at 10/1000µs.
