SMAZ5925B-E3

Vishay Intertech · Zener Diodes · DO-214AC(SMA)

SMAZ5925B-E3 from Vishay Intertech, in a DO-214AC(SMA). 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 Zener diode, marked by the color band; positive side in Zener (reverse) regulation, with VZ of 9.5 V min to 10.5 V max at IZT = 37.5 mA for the SMAZ5925B.
2 Anode passive Anode terminal of the Zener diode, opposite the cathode band; maximum instantaneous forward voltage is 1.5 V at 200 mA.
