PDZ7.5B from JSMSEMI, in a SOD-323. 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 of the Zener diode, identified by the marking bar on the package; PDZ7.5B has a working voltage of 7.28 V to 7.60 V at IZ = 5 mA. |
| 2 | A | passive | Anode of the Zener diode; continuous forward current is limited to 200 mA and VF is at most 0.9 V at IF = 10 mA. |
