Product details
Overview
DDZ9697S-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal Zener voltage of 10.0 V (min 9.50 V, max 10.50 V), 50 µA test current (IZT), 0.1 µA reverse leakage at 7.6 V (VR), and 200 mW power dissipation in SOD-323 package. It delivers sharp breakdown characteristics and tight ±5% VZ tolerance for voltage reference and regulation in low-power analog circuits.
For engineers reviewing the DDZ9697S-7 datasheet, DDZ9697S-7 pinout, DDZ9697S-7 application, or DDZ9697S-7 equivalent, this part serves as a stable, RoHS-compliant, low-leakage 10 V reference in space-constrained designs requiring thermal stability and automated assembly compatibility.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with tightly controlled voltage regulation across 5–100 mA Zener current range. Its 625 °C/W junction-to-ambient thermal resistance reflects performance on standard FR-4 PCBs using recommended pad layout.
The device exhibits a temperature coefficient of approximately +0.05 %/°C near 10 V (per Fig. 18), enabling predictable drift behavior in ambient ranges from –65 °C to +150 °C. Its 1.0 pF typical capacitance at 1 MHz supports high-frequency noise filtering without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.0 V nominal (9.50–10.50 V), enabling precise 10 V reference generation with ±5% initial tolerance. |
| Zener Test Current (IZT) | 50 µA - defines the operating point where VZ is specified; suitable for ultra-low-power biasing. |
| Reverse Leakage (IR) | 0.1 µA at VR = 7.6 V - ensures minimal error current in high-impedance reference nodes. |
| Power Dissipation (PD) | 200 mW - sets maximum continuous power handling on standard FR-4 board with defined pad layout. |
| Thermal Resistance (RθJA) | 625 °C/W - quantifies self-heating impact; limits safe DC current to ~12.6 mA at TA = 70 °C. |
| Package | SOD-323 - 2-pin surface-mount outline (2.3–2.7 mm length) compatible with 0402 footprint automation. |
| Operating Temperature | –65 °C to +150 °C - supports industrial and automotive under-hood applications with full parameter validity. |
Pinout & Package
Package: SOD-323 - ultra-small plastic case (2.5 mm × 1.3 mm × 0.9 mm), cathode-banded, matte tin-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Same 10 V nominal, but ±6% tolerance (vs. ±5%), higher IR (0.5 µA @ 7.6 V), SOT-23 package. | Larger footprint; less suitable for ultra-dense layouts where SOD-323 saves >30% board area. | Select when existing SOT-23 tooling or higher surge robustness is prioritized over size and leakage. |
| MMSZ5240B-7-F | 10 V nominal, ±5% tolerance, but 20 µA IZT (vs. 50 µA), higher Zener impedance (~20 Ω vs. ~15 Ω). | Requires higher bias current for regulation stability; less optimal in low-IQ systems. | Prefer when legacy MMSZ footprint compatibility is required and 20 µA minimum bias is acceptable. |
Compared with BZX84-C10LT1G and MMSZ5240B-7-F, DDZ9697S-7 offers the lowest leakage and smallest footprint among 10 V Zeners with ±5% tolerance, making it optimal for miniaturized, battery-sensitive designs where regulation stability at microamp bias matters.

FAQ
What is the maximum continuous Zener current for DDZ9697S-7 at 70°C ambient?
At TA = 70 °C, derated power dissipation is 150 mW (per Fig. 1). With VZ ≈ 10 V, maximum continuous Zener current is 15 mA. Exceeding this risks thermal runaway due to the 625 °C/W RθJA and limited PCB copper area in SOD-323 layout.
Does DDZ9697S-7 require external current limiting in shunt regulator configuration?
Yes - a series current-limiting resistor is mandatory. For example, with VIN = 12 V and desired IZ = 50 µA, a 40 kΩ resistor sets bias while maintaining regulation. Without it, excessive current causes irreversible junction damage even at low input voltages.
Is DDZ9697S-7 qualified for automotive applications per AEC-Q101?
No - DDZ9697S-7 is not AEC-Q101 qualified. The datasheet lists DDZ9705S (18 V variant) as AEC-Q101 qualified (Note 5), but DDZ9697S-7 lacks that qualification and is intended for industrial and commercial use only.
How does the temperature coefficient affect accuracy in a 0–70°C operating range?
Per Fig. 18, TC ≈ +0.05 %/°C at 10 V. Over 70°C ΔT, total drift is ~35 mV (0.35%), contributing <±0.35% gain error in reference-dependent measurements unless compensated via calibration or layout symmetry.
