SZMM5Z10VT1G from onsemi, in a SOD-523. 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, identified by the polarity band on the SOD-523 outline (Style 1); the datasheet gives no separate pin-level electrical limit, and the device ratings are total dissipation of 500 mW (FR-4, 1 cm² pad) and junction/storage temperature of -65 to +150 °C. |
| 2 | Anode | passive | Anode terminal of the Zener diode; the datasheet gives no separate pin-level electrical limit, and the device ratings are total dissipation of 500 mW (FR-4, 1 cm² pad) and junction/storage temperature of -65 to +150 °C. |
