30KPA33A

Littelfuse · TVS · P600

30KPA33A from Littelfuse, in a P600. 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 lead of the unidirectional TVS, marked by the color band, with 33 V reverse standoff voltage and 36.90 V to 40.59 V breakdown at 50 mA for the 30KPA33A-HRA.
2 Anode passive Anode lead of the unidirectional TVS, with a maximum clamping voltage of 58.5 V at 517.9 A peak pulse current for the 30KPA33A-HRA.
