SZ15B0 from EIC Semicon, 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 | K | passive | Cathode, the end marked with the color band; the zener is reverse-biased here, with SZ15B0 VZ 100 V nominal at IZT 2.5 mA and maximum DC zener current IZM 9.0 mA. |
| 2 | A | passive | Anode; the opposite end from the color band, with maximum forward voltage 1.2 V at IF = 200 mA. |
