Product details
Overview
DDZ9713Q-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 50 µA test current-ideal for low-bias, battery-powered voltage reference and regulation in portable electronics.
For engineers reviewing the DDZ9713Q-7 datasheet, DDZ9713Q-7 pinout, DDZ9713Q-7 application, or DDZ9713Q-7 equivalent, this AEC-Q101 qualified, SOD123-packaged Zener diode supports automotive-grade voltage clamping, precision biasing, and overvoltage protection where stable low-leakage performance (<0.05 µA @ 22.8 V) and tight voltage tolerance (±5%) are required.
Technical Context
This device operates as a two-terminal, reverse-biased voltage reference with sharp breakdown characteristics at 30 V, optimized for low-test-current operation (IZT = 50 µA) to minimize quiescent power draw. Its thermal resistance junction-to-lead is 150 °C/W, enabling reliable operation up to +150°C junction temperature.
The diode exhibits a positive temperature coefficient (~0.07 %/°C at 30 V, per Fig. 19), indicating predictable voltage drift with temperature-critical for stable reference design in automotive ambient ranges (−40°C to +125°C operating envelope).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30LT1G | Same 30 V nominal VZ, but rated for 350 mW PD and higher IR (1 µA @ 24 V) | Not AEC-Q101 qualified; suitable for commercial-grade portable devices only | Select when cost sensitivity outweighs automotive qualification and leakage requirements |
| MMSZ5256ET1G | 30 V VZ, 500 mW PD, but wider tolerance (±5% min/max not guaranteed), no AEC-Q101 status | Limited thermal stability; TC not characterized across full temp range | Choose only for non-automotive, non-critical reference roles where traceability and long-term drift are secondary |
Compared with BZX84-C30LT1G and MMSZ5256ET1G, DDZ9713Q-7 delivers superior leakage performance (0.05 µA vs. ≥1 µA), guaranteed AEC-Q101 qualification, and documented temperature coefficient behavior-making it the sole choice for automotive and high-reliability portable instrumentation.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9713Q-7 guarantees ≤0.05 µA leakage?
DDZ9713Q-7 guarantees ≤0.05 µA reverse leakage current at VR = 22.8 V, as specified in the Electrical Characteristics table. This value is measured under standard conditions (TA = +25°C) using short-duration pulse testing to avoid self-heating effects.
Does DDZ9713Q-7 have a defined zener impedance (ZZT) at 30 V?
Yes-zener impedance is characterized across the DDZ97xx series. For DDZ9713Q-7 (30 V), typical ZZT is ~120 Ω at IZT = 50 µA (inferred from Fig. 15 trend and adjacent part data), confirming stable regulation under light-load conditions.
Can DDZ9713Q-7 be used in place of a 24 V Zener diode for overvoltage protection?
No-DDZ9713Q-7 is a 30 V nominal device. Substituting it for a 24 V Zener would raise the clamping threshold by 6 V, potentially exposing downstream circuitry to damaging overvoltage. Always match nominal VZ to system protection requirements.
Is the SOD123 package of DDZ9713Q-7 compatible with IPC-7351B standard land patterns?
Yes-the SOD123 outline dimensions (E = 2.65 mm, D = 1.55 mm, L = 0.30 mm) align with IPC-7351B generic SOD-123 footprint recommendations. Diodes Incorporated's suggested pad layout (available at diodes.com/package-outlines.html) meets IPC-7351B Class B tolerances.
