Product details
Overview
DDZ9699Q-7 from Diodes Incorporated is a surface-mount, low-current Zener diode with a nominal zener voltage of 12 V (min 11.4 V, max 12.6 V), rated for 500 mW power dissipation on FR-4 PCB at TL = +75°C, and specified at 50 µA test current - optimized for low-bias, battery-powered systems such as portable sensor nodes and wearables.
For engineers reviewing the DDZ9699Q-7 datasheet, DDZ9699Q-7 pinout, DDZ9699Q-7 application, or DDZ9699Q-7 equivalent, this AEC-Q101 qualified SOD123 device offers automotive-grade reliability, tight zener voltage tolerance (±5%), low leakage (<0.05 µA @ 9.1 V), and thermal stability critical for precision voltage reference and overvoltage protection in constrained-space designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under low-current conditions. Its 50 µA test current enables accurate characterization in ultra-low-power circuits where traditional 5 mA Zeners would draw excessive bias current.
The device exhibits a temperature coefficient of approximately +0.06 %/°C near 12 V (per Fig. 18), enabling predictable drift compensation in temperature-sensitive references. Its SOD123 package delivers low thermal resistance (RθJL = 150 °C/W) and supports automated assembly without lead-free compatibility concerns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C12LT1G | Same 12 V nominal, but rated at 300 mW PD and 5 mA IZT; higher leakage (1 µA @ 9.1 V). | Lacks AEC-Q101 qualification; not validated for automotive temperature cycling or PPAP. | Select when cost sensitivity outweighs automotive compliance and ultra-low leakage requirements. |
| MMSZ5242B-TP | 12 V nominal, 500 mW rating, but uses SOD-123 package with ±5% tolerance and 100 nA leakage @ 9.1 V - tighter leakage spec. | No AEC-Q101 documentation; RoHS-compliant but not explicitly automotive-process certified. | Prefer for industrial medical devices needing lowest possible leakage, where automotive traceability is not mandated. |
Compared with BZX84-C12LT1G and MMSZ5242B-TP, DDZ9699Q-7 uniquely combines AEC-Q101 qualification, 50 µA test current, and <0.05 µA leakage - making it the only choice for automotive body electronics requiring both regulatory compliance and nanoampere-level bias efficiency.

FAQ
What is the maximum reverse leakage current for DDZ9699Q-7 at 9.1 V?
The maximum reverse leakage current is 0.05 µA at VR = 9.1 V, measured per DS30410 Rev. 17–2, Table "Electrical Characteristics". This value is confirmed under standard test conditions (TA = +25°C) and reflects the device's suitability for ultra-low-power standby circuits where leakage must remain below 100 nA.
Is DDZ9699Q-7 compatible with lead-free reflow profiles?
Yes - DDZ9699Q-7 features matte tin annealed terminals and is rated for standard lead-free reflow (JEDEC J-STD-020 Level 1). Its SOD123 package withstands peak temperatures up to 260°C for ≤60 seconds, and moisture sensitivity is rated at Level 1, eliminating bake requirements prior to assembly.
How does the temperature coefficient behave near 12 V?
Per Figure 18 in DS30410, the temperature coefficient is approximately +0.06 %/°C at 12 V. This positive drift means VZ increases by ~7.2 mV/°C, enabling predictable compensation in reference circuits where ambient variation exceeds ±20°C.
Can DDZ9699Q-7 be used as a replacement for DDZ9699-7 in non-automotive designs?
Yes - the Q suffix denotes AEC-Q101 qualification and IATF 16949 manufacturing, but electrically and mechanically, DDZ9699Q-7 is identical to DDZ9699-7 (same VZ, IZT, package, and markings). The Q version adds automotive change control and PPAP documentation, with no performance trade-offs in commercial applications.
