Product details
Overview
DDZ9713-7 from Diodes Incorporated is a surface-mount low-current Zener diode with a nominal zener voltage of 30 V (min 28.5 V, max 31.5 V), rated for 500 mW power dissipation on FR-4 PCB at TL = +75°C, and specified at a low test current of 50 µA - ideal for precision voltage reference and low-bias regulation in portable battery-powered systems.
For engineers reviewing the DDZ9713-7 datasheet, DDZ9713-7 pinout, DDZ9713-7 application, or DDZ9713-7 equivalent, this device serves as a stable, low-leakage (0.05 µA @ 22.8 V) voltage clamp in power supply monitoring, overvoltage protection, and analog signal conditioning circuits where SOD123 footprint compatibility and AEC-Q101 qualification are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its low 50 µA test current enables accurate regulation in ultra-low-power circuits, while its ±5% zener voltage tolerance (28.5–31.5 V) ensures predictable clamping behavior.
The device exhibits a positive temperature coefficient of approximately +0.08 %/°C near 30 V (per Fig. 19), enabling predictable drift compensation in multi-device references. Thermal resistance junction-to-lead is 150 °C/W, supporting reliable operation up to +150°C storage and operating temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30LT1G | Same 30 V nominal, but 350 mW rating and ±5% tolerance; higher IR (1 µA @ 22.8 V) | Limited to lower-power consumer applications due to reduced power handling and higher leakage | Prefer DDZ9713-7 where >500 mW surge capability or sub-0.1 µA leakage is required |
| MMSZ5256ET1G | 30 V nominal, 500 mW rating, but 20 µA test current and higher zener impedance (>120 Ω) | Less stable regulation under dynamic load; unsuitable for precision reference buffering | Choose DDZ9713-7 for low-IZT stability and tighter TC performance in measurement circuits |
Compared with BZX84-C30LT1G and MMSZ5256ET1G, DDZ9713-7 delivers superior low-leakage performance, lower thermal resistance, and automotive-grade qualification - making it the preferred choice for battery-critical and high-reliability industrial designs.

FAQ
What is the maximum reverse voltage before breakdown for DDZ9713-7?
The DDZ9713-7 begins controlled reverse breakdown at its nominal zener voltage of 30 V, with guaranteed operation between 28.5 V (minimum) and 31.5 V (maximum) at 50 µA test current. It is not rated for sustained operation above 31.5 V in breakdown - exceeding this risks thermal runaway if power dissipation limits are violated.
Can DDZ9713-7 be used in place of a 24 V Zener diode?
No - DDZ9713-7 is a fixed 30 V nominal Zener and is not interchangeable with 24 V devices. Substituting it for a 24 V part would raise the clamping threshold by 6 V, potentially allowing damaging overvoltage on protected circuits. Always match nominal zener voltage to system rail requirements.
Is the SOD123 package lead-free and RoHS compliant?
Yes - DDZ9713-7 is fully lead-free and RoHS 3 compliant (2015/863/EU), with matte tin annealed terminals over Alloy 42 leadframe. It meets UL 94V-0 flammability rating and is halogen- and antimony-free per Diodes Incorporated's "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb).
Does DDZ9713-7 require a heatsink in standard PCB layouts?
No - the SOD123 package is rated for 500 mW dissipation on FR-4 with minimum recommended pad layout (per Diodes' Suggested Pad Layout document). Heatsinking is unnecessary unless continuous power exceeds 500 mW or ambient temperature exceeds +75°C - in which case derating per Fig. 1 must be applied.
