Product details
Overview
DDZ9701-7 from Diodes Incorporated is a surface-mount low-current Zener diode with a nominal zener voltage of 14.0 V (min 13.3 V, max 14.7 V), rated for 500 mW power dissipation on FR-4 PCB at TL = +75°C, specified at 50 µA test current, and housed in an SOD123 package. It serves as a precision voltage reference or overvoltage clamp in low-power analog monitoring circuits, battery management systems, and portable sensor signal conditioning stages.
For engineers reviewing the DDZ9701-7 datasheet, DDZ9701-7 pinout, DDZ9701-7 application, or DDZ9701-7 equivalent, key selection criteria include its 14 V zener voltage tolerance, 0.05 µA reverse leakage at 10.6 V, temperature coefficient of ~+0.07 %/°C (inferred from Fig. 18), SOD123 thermal resistance (RθJA = 340 °C/W), and suitability for automated assembly in space-constrained consumer and industrial PCBs.
Technical Context
This device operates in reverse breakdown mode to maintain stable voltage regulation under low bias conditions. Its 50 µA test current enables accurate characterization in micro-power circuits where traditional 5 mA zener test currents would cause excessive quiescent draw.
The SOD123 package provides defined thermal resistance values (RθJA = 340 °C/W, RθJL = 150 °C/W) and moisture sensitivity level 1 compliance, supporting reliable reflow soldering and long-term stability in ambient temperatures from –65°C to +150°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15-7-F | 15 V nominal, ±5% tolerance, 300 mW rating, SOT-23 package, RθJA ≈ 370 °C/W | Higher voltage, lower power, smaller package - less thermal margin but better fit for ultra-dense layouts | Select when 15 V reference suffices and board space is constrained; verify thermal rise under 50 µA bias |
| MMSZ5241B-7-F | 14 V nominal, ±5% tolerance, 500 mW rating, SOD-123 package, IR = 0.1 µA @ 11.2 V | Nearly identical electrical specs but higher leakage - may affect ultra-low-power sleep-mode accuracy | Prefer for cost-sensitive non-battery applications; avoid in sub-1 µA standby systems where leakage dominates error budget |
Compared with BZX84-C15-7-F and MMSZ5241B-7-F, DDZ9701-7 offers tighter leakage (0.05 µA vs. 0.1 µA) and superior thermal performance (RθJA = 340 °C/W) in the same SOD123 footprint, making it optimal for precision, low-quiescent, thermally challenged designs.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9701-7 guarantees ≤0.05 µA leakage?
Per the Electrical Characteristics table, DDZ9701-7 guarantees a maximum reverse leakage current of 0.05 µA at VR = 10.6 V. This value is specified under standard test conditions (TA = +25°C) and reflects the voltage below the zener knee where leakage remains tightly controlled-critical for minimizing standby power in always-on circuits.
Can DDZ9701-7 be used in place of a 13.8 V automotive supply monitor?
Yes-its 14.0 V nominal zener voltage (13.3–14.7 V range) aligns with typical 12 V system overvoltage thresholds. When reverse-biased across a resistor from a 13.8 V rail, it conducts only above ~13.3 V, enabling robust detection of alternator over-regulation or load dump precursors without false triggering.
Does DDZ9701-7 have AEC-Q101 qualification?
No-DDZ9701-7 is the standard-grade part. The automotive-qualified version is DDZ9701Q-7, which carries AEC-Q101 qualification, PPAP capability, and is manufactured in IATF 16949-certified facilities. For automotive applications requiring change control and qualification documentation, DDZ9701Q-7 must be selected.
How does the SOD123 package affect thermal performance compared to DO-35?
The SOD123 package delivers RθJA = 340 °C/W on FR-4 (vs. ~500 °C/W for DO-35), due to optimized leadframe thermal path and standardized surface-mount pad layout. This 32% lower thermal resistance enables higher sustained power handling in compact PCBs, especially when using Diodes Incorporated's recommended 1-inch² copper pad per the Suggested Pad Layout document.
