Product details
Overview
DDZ9715S-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal Zener voltage 36 V, tolerance ±5% (34.2–37.8 V), maximum reverse leakage current 0.05 μA at 27.3 V, power dissipation 200 mW, and SOD-323 package. It delivers stable voltage reference in low-power analog circuits, voltage regulation for sensor biasing, and overvoltage protection in portable instrumentation.
For engineers reviewing the DDZ9715S-7 datasheet, DDZ9715S-7 pinout, DDZ9715S-7 application, or DDZ9715S-7 equivalent, key selection criteria include Zener voltage accuracy at IZT = 50 μA, low temperature coefficient (~0.09 %/°C per Fig. 20), tight leakage spec, thermal resistance (625 °C/W), and RoHS-compliant "Green" molding compound suitability for automated assembly.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining regulated output by conducting reverse current above its specified breakdown threshold. Its sharp knee characteristics and low dynamic impedance (≈120 Ω at IZ = 1 mA, inferred from Fig. 16) support high-precision feedback paths in analog power supplies and ADC reference buffers.
Designed for thermal stability in compact layouts, it exhibits a positive temperature coefficient of approximately +0.09 %/°C near 36 V (Fig. 20), enabling predictable drift compensation in temperature-critical references. The SOD-323 package's low thermal resistance and moisture sensitivity level 1 rating ensure robust performance in reflow-soldered consumer and industrial PCBs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36LT1G | Same 36 V nominal, ±5% tolerance, but higher max leakage (1 μA @ 27.3 V) and 350 mW PD | Higher power handling suits higher-current clamping; less suitable for ultra-low-leakage references | Select when surge energy absorption >200 mW is required and leakage <0.1 μA is not critical |
| MMSZ5245B-TP | 36 V nominal, ±5%, but SOD-123 package (larger footprint) and higher RθJA (833 °C/W) | Lower thermal efficiency limits continuous current in dense layouts; same leakage spec (0.1 μA) | Choose only if SOD-123 is already standardized in design and board space permits larger footprint |
Compared with BZX84-C36LT1G and MMSZ5245B-TP, DDZ9715S-7 offers the lowest leakage (0.05 μA) and smallest thermal resistance (625 °C/W) in SOD-323, making it optimal for space-constrained, low-quiescent-current precision references where thermal management is critical.

FAQ
What is the recommended test current (IZT) for specifying Zener voltage?
The datasheet specifies Zener voltage at IZT = 50 μA. This low test current enables accurate characterization of low-power reference behavior while minimizing self-heating. For stable operation, typical bias current ranges from 100 μA to 5 mA depending on load and noise requirements.
Does DDZ9715S-7 have AEC-Q101 qualification?
No - DDZ9715S-7 is not AEC-Q101 qualified. Only DDZ9705S (marked with Note 5 in the Electrical Characteristics table) carries AEC-Q101 qualification. DDZ9715S-7 is rated for industrial temperature range (−65 to +150 °C) but lacks automotive stress-test validation.
How does the temperature coefficient affect voltage stability over temperature?
Per Figure 20, DDZ9715S-7 exhibits a temperature coefficient of approximately +0.09 %/°C near 36 V. Over a 100 °C range (−25 to +75 °C), this results in ~±0.9 V drift, which must be accounted for in high-accuracy applications; external compensation may be needed for sub-0.1% total error.
Can DDZ9715S-7 be used in parallel for higher power dissipation?
No - Zener diodes should not be paralleled due to mismatched breakdown voltages causing current hogging. For higher power, use a single higher-rated Zener (e.g., 500 mW through-hole type) or add a series pass transistor; the SOD-323 package is not designed for parallel operation.
