Product details
Overview
DDZ9691Q-13 from Diodes Incorporated is a surface-mount, low-current Zener diode with a nominal zener voltage of 6.2 V (min 5.89 V, max 6.51 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 AEC-Q101 qualified SOD123 package for automotive applications including voltage reference and overvoltage protection in battery-powered ECUs.
For engineers reviewing the DDZ9691Q-13 datasheet, DDZ9691Q-13 pinout, DDZ9691Q-13 application, or DDZ9691Q-13 equivalent, this part supports low-bias precision regulation in space-constrained automotive modules where thermal stability, RoHS/Green compliance, and PPAP-capable sourcing are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 50 µA test current enables accurate regulation in ultra-low-power circuits, and its ±5% zener voltage tolerance (6.2 V ±0.31 V) ensures predictable clamping behavior in feedback paths.
The device exhibits a typical zener impedance of 120 Ω at IZ = 1 mA and a temperature coefficient of approximately +0.04 %/°C near 6.2 V, indicating positive drift with rising junction temperature - a key consideration when designing for thermal compensation in analog sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2-7-F | Same 6.2 V nominal, but rated for 300 mW only and not AEC-Q101 qualified | Limited to industrial/commercial use; lacks PPAP documentation and automotive thermal validation | Select only for non-automotive designs where cost sensitivity outweighs qualification requirements |
| MMSZ4687T1G | 6.2 V nominal, 500 mW rating, but specified at 20 mA IZT (not 50 µA); higher leakage (5 µA @ 5 V) | Higher bias current demand conflicts with micropower sensor nodes; less suitable for battery-backed circuits | Prefer when higher test current simplifies bias network design and automotive qualification is not required |
Compared with BZX84-C6V2-7-F and MMSZ4687T1G, DDZ9691Q-13 uniquely combines AEC-Q101 qualification, 50 µA test current, and 500 mW dissipation - making it the only choice for automotive-grade, low-power voltage reference in safety-critical modules.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9691Q-13 guarantees ≤1 µA leakage?
Per the Electrical Characteristics table, DDZ9691Q-13 guarantees ≤1 µA reverse leakage current at VR = 5 V. This value is measured under standard test conditions (TA = +25°C) and defines the upper limit of applied reverse voltage before significant leakage begins - critical for maintaining low quiescent current in always-on vehicle subsystems.
Is DDZ9691Q-13 compatible with lead-free reflow profiles?
Yes. The device uses matte tin-annealed terminals over Alloy 42 leadframe and is rated for solderability per MIL-STD-202, Method 208. Its SOD123 package withstands JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard Pb-free reflow profiles up to 260°C peak temperature.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
DDZ9691Q-13 has a typical temperature coefficient of +0.04 %/°C near 6.2 V. Over -40°C to +125°C, this results in ~±65 mV total drift (≈±1.05%), which is acceptable for non-precision references but requires compensation in high-accuracy ADC reference paths.
Can DDZ9691Q-13 replace DDZ9691-13 in existing designs?
Yes - DDZ9691Q-13 is the automotive-qualified variant of DDZ9691-13, sharing identical electrical specs and SOD123 packaging. The "Q" suffix denotes AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing, with no performance trade-offs versus the commercial version.
