SMAJ5.0A-AT

Brightking Elec (TAIWAN) · TVS · SMA(DO-214AC)

SMAJ5.0A-AT from Brightking Elec (TAIWAN), in a SMA(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 K passive Cathode, marked by the color band on the unidirectional SMAJ5.0A-AT (VRWM 5.0V, VBR 6.40~7.00V at 10mA, VC 9.2V at 43.5A IPP).
2 A passive Anode terminal of the unidirectional SMAJ5.0A-AT, which conducts forward with a peak forward surge current (IFSM) of 40A.
