onsemi · Zener Diodes · SOD-523
SZMM5Z4688T1G 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, marked by the polarity band on the package (Style 1 outline, pin 1 = cathode); the Zener regulating terminal of the MM5Z4688 (nominal VZ 4.7 V, IZT 50 µA, max IR 10 µA at VR 3 V per the electrical table). |
| 2 | Anode | passive | Anode, the terminal opposite the cathode band (Style 1 outline, pin 2 = anode); the datasheet gives no separate pin-level limits for this terminal. |
