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. |
