Product details
Overview
DDZ9697Q-7 from Diodes Incorporated is a surface-mount, low-current Zener diode in SOD123 package, rated for 10 V nominal zener voltage (9.50–10.50 V at IZT = 50 µA), 500 mW power dissipation on FR-4 PCB at TL = +75°C, and reverse leakage current ≤0.1 µA at VR = 7.6 V. It is AEC-Q101 qualified and designed for precision voltage reference and overvoltage protection in automotive sensor signal conditioning circuits.
For engineers reviewing the DDZ9697Q-7 datasheet, DDZ9697Q-7 pinout, DDZ9697Q-7 application, or DDZ9697Q-7 equivalent, this part serves as a stable, low-bias zener reference in battery-powered ECUs, CAN node voltage clamping, and low-power analog front-end regulation where thermal stability and automotive-grade reliability are required.
Technical Context
This device operates as a two-terminal voltage reference with cathode-band polarity, leveraging silicon planar Zener breakdown at low test current (50 µA) to minimize self-heating and enable accurate low-power biasing. Its temperature coefficient is +0.04 %/°C near 10 V, confirmed by Fig. 18 of DS30410 Rev. 17–2.
The SOD123 package provides defined thermal resistance (RθJA = 340 °C/W, RθJL = 150 °C/W) and moisture sensitivity level 1 compliance, supporting reflow soldering per J-STD-020 and automated placement in high-reliability automotive assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.50–10.50 V at IZT = 50 µA - ensures tight tolerance for 10 V reference applications under minimal bias. |
| Power Dissipation (PD) | 500 mW on FR-4 PCB at TL = +75°C - defines maximum continuous power handling in standard layout. |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 7.6 V - guarantees negligible quiescent current draw in standby mode. |
| Thermal Resistance (RθJA) | 340 °C/W - determines junction-to-ambient temperature rise under load, critical for thermal design margin. |
| Operating Temperature | −65 to +150 °C - supports full automotive under-hood and cabin operating ranges. |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing control. |
Pinout & Package
Package: SOD123 - surface-mount plastic case (UL 94V-0), 0.01 g weight, cathode band marking, matte tin annealed terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener reference ground node | Connected to circuit ground or lower-potential rail; forms reference return path during regulation. |
| Cathode | Zener breakdown terminal / regulated output node | Connected to voltage source or signal line requiring clamping; delivers stable 10 V reference when reverse biased. |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at IZT = 50 µA - enables use in microamp-level bias networks without compromising regulation accuracy. |
| AEC-Q101 qualification | Validated for automotive applications with change control, PPAP support, and IATF 16949 production - reduces qualification effort for Tier 1 suppliers. |
| SOD123 footprint compatibility | Standardized 2.65 mm × 1.55 mm body with 0.57 mm lead width - ensures drop-in replacement in existing layouts and compatibility with industry-standard pick-and-place equipment. |
| Halogen- and antimony-free "Green" construction | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - meets global environmental compliance mandates including RoHS 3 and automotive ELV directives. |

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 rating but higher IZT = 5 mA; RθJA = 375 °C/W; no AEC-Q101 qualification. | Not suitable for automotive PPAP; acceptable for industrial PCBs with adequate heatsinking. | Select only for non-automotive cost-sensitive designs where 50 µA bias is not required. |
| MMSZ4686T1G | 10 V rating at IZT = 5 mA; tighter VZ tolerance (±5% vs ±5%); RθJA = 350 °C/W; AEC-Q101 qualified. | Higher test current increases quiescent power; less suitable for ultra-low-power wake-up circuits. | Prefer when higher zener impedance stability at >1 mA is needed, e.g., in linear regulator feedback paths. |
Compared with BZX84-C10LT1G and MMSZ4686T1G, DDZ9697Q-7 uniquely balances ultra-low bias current (50 µA), automotive qualification, and tight thermal resistance control-making it optimal for always-on sensor nodes where power budget and qualification rigor are both critical.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9697Q-7 guarantees ≤0.1 µA leakage?
DDZ9697Q-7 guarantees reverse leakage current ≤0.1 µA at VR = 7.6 V, as specified in the Electrical Characteristics table of DS30410 Rev. 17–2. This value is measured under DC conditions at TA = +25°C and defines the upper limit of safe reverse bias before measurable leakage begins.
Does DDZ9697Q-7 require external current limiting in series with its cathode?
Yes - like all Zener diodes, DDZ9697Q-7 requires a series current-limiting resistor to set IZ within its specified test range (50 µA) or safe operating area (≤500 mW). The resistor value must be calculated based on source voltage, desired zener current, and thermal derating above +75°C.
Can DDZ9697Q-7 be used in parallel with other Zeners for higher power handling?
No - parallel connection of Zener diodes is not recommended due to mismatched breakdown voltages causing current hogging. Each DDZ9697Q-7 must operate independently with its own current-limiting resistor; for higher power, select a single higher-rated device or use active regulation.
Is the SOD123 package of DDZ9697Q-7 compatible with IPC-7351B standard land patterns?
Yes - the SOD123 outline dimensions (E = 2.65 mm, D = 1.55 mm, b = 0.57 mm) align with IPC-7351B "SOD-123" generic footprint. Diodes Incorporated's suggested pad layout (available at diodes.com/package-outlines.html) complies with IPC-7351B Class L tolerances for automated assembly yield.
