SMLJ13A

BOURNS · TVS · SMC(DO-214AB)

SMLJ13A from BOURNS, in a SMC(DO-214AB). 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 K passive Cathode, marked by the cathode band on the unidirectional SMLJ13A (VRWM 13 V, VBR 14.4 to 15.9 V at 1 mA, VC 21.5 V at 139.4 A on 10/1000 µs).
2 A passive Anode of the unidirectional SMLJ13A, the terminal opposite the cathode band, which is the return side of the clamp.
