Diodes Incorporated · Zener diode · SOD-123
500 mW surface-mount silicon planar Zener diode with a nominal 5.1 V breakdown, in a SOD-123 package. The Zener voltage is 4.8-5.4 V at a 5 mA test current, and the cathode band marks polarity. Used for voltage clamping, simple shunt references, and rail protection. Reverse-biased above Vz it conducts and holds the voltage; forward drop is 0.9 V.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the Zener diode. Marked by the cathode band on the SOD-123 package top. Reverse-breakdown at nominally 5.1 V (4.8–5.4 V) when biased more positive than the anode by Vz; test current Izt = 5 mA, Zzt = 60 Ω, Ir ≤ 2.0 µA @ Vr = 2.0 V. |
| 2 | A | passive | Anode of the Zener diode. Forward voltage Vf = 0.9 V @ If = 10 mA; typical Zener operation reverse-biases anode negative with respect to cathode. |
