Product details
Overview
DDZ9692Q-7 from Diodes Incorporated is a surface-mount, low-current Zener diode in SOD123 package, rated for 6.8 V nominal zener voltage (6.46–7.14 V), 50 µA test current, and 500 mW power dissipation at TL = +75°C on FR-4 PCB. It features 0.1 µA maximum reverse leakage at VR = 5.1 V and AEC-Q101 qualification for automotive applications.
For engineers reviewing the DDZ9692Q-7 datasheet, DDZ9692Q-7 pinout, DDZ9692Q-7 application, or DDZ9692Q-7 equivalent, this device serves as a precision voltage reference and overvoltage clamp in low-power sensor interfaces, battery monitoring circuits, and automotive body control modules where stable low-bias operation and IATF 16949 traceability are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under controlled current conditions. Its low 50 µA test current enables use in ultra-low-power systems, while its ±5% zener voltage tolerance and <0.1%/°C temperature coefficient near 6.8 V ensure predictable regulation in ambient temperature ranges from –65°C to +150°C.
The device uses a planar epitaxial construction with matte tin–annealed Alloy 42 leadframe, delivering robust solderability per MIL-STD-202 Method 208 and moisture sensitivity level 1 per J-STD-020. Its SOD123 package provides compact footprint (2.65 mm × 1.55 mm) and thermal resistance of 150°C/W junction-to-lead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8-7-F | Same 6.8 V nominal, but SOT-23 package; 350 mW PD; no AEC-Q101 qualification | Limited to commercial-grade portable electronics; lacks automotive change control and PPAP support | Select when cost and board space are prioritized over automotive compliance and long-term supply continuity |
| MMSZ4687T1G | 6.8 V nominal, SOD-123 package, but 500 mW PD and AEC-Q101 qualified; higher IR (1 µA @ 5.1 V) | Acceptable for non-critical automotive subsystems; less suitable for ultra-low-leakage battery monitoring | Choose when needing second-source availability with identical package but tolerating 10× higher leakage current |
Compared with BZX84-C6V8-7-F and MMSZ4687T1G, DDZ9692Q-7 uniquely combines AEC-Q101 qualification, 0.1 µA leakage, and SOD123 compatibility-making it optimal for safety-conscious automotive and medical-edge designs where leakage, traceability, and thermal performance are jointly constrained.

FAQ
What is the maximum reverse leakage current for DDZ9692Q-7, and at what voltage is it specified?
The maximum reverse leakage current is 0.1 µA, measured at VR = 5.1 V (i.e., 75% of nominal zener voltage). This value is guaranteed per DS30410 Rev. 17–2, page 2, Electrical Characteristics table, and reflects the device's suitability for ultra-low-power bias networks where leakage must remain sub-nanoampere.
Is DDZ9692Q-7 compatible with lead-free reflow soldering processes?
Yes-DDZ9692Q-7 uses a matte tin–annealed Alloy 42 leadframe and meets JEDEC J-STD-020 moisture sensitivity level 1. It is fully compatible with standard Pb-free reflow profiles (peak 260°C), requires no baking, and passes solderability testing per MIL-STD-202, Method 208.
Does DDZ9692Q-7 have a specified zener impedance, and what is its typical value?
Yes-typical zener impedance (ZZT) is 30 Ω at IZT = 50 µA and TJ = 25°C, as shown in Figure 11 of DS30410. This low dynamic impedance ensures minimal voltage deviation under small-signal load variations, supporting stable reference performance in precision analog circuits.
Can DDZ9692Q-7 be used in place of a standard 6.8 V Zener in non-automotive applications?
Yes-it functions identically to commercial-grade 6.8 V Zeners in electrical behavior, but its AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing add no functional penalty. Engineers may deploy it in industrial or medical designs where enhanced process control and supply-chain assurance are valued, even without formal automotive requirements.
