SMBJ24A-Q

BOURNS · TVS · SMB(DO-214AA)

SMBJ24A-Q from BOURNS, in a SMB(DO-214AA). 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 terminal, marked by the cathode band on the unidirectional SMBJ24A-Q (VRWM 24 V, VBR 26.7-29.5 V at 1.0 mA, max clamping 38.9 V at 15.5 A 10/1000 µs).
2 A passive Anode terminal, the end opposite the cathode band on the unidirectional SMBJ24A-Q (600 W peak pulse power at TP = 1 ms).
