P4SMA13A

Littelfuse · TVS · DO-214AC

P4SMA13A from Littelfuse, in a DO-214AC. 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 diode, marked by the color band on the DO-214AC (SMA) body and the positive end of the device.
2 Anode passive Anode terminal of the unidirectional TVS diode, opposite the cathode band end of the DO-214AC (SMA) body.
