Product details
Overview
DDZ9696-7 from Diodes Incorporated is a surface-mount low-current Zener diode in SOD123 package, rated for 9.1 V nominal zener voltage (min 8.65 V, max 9.56 V) at 50 µA test current, with 500 mW power dissipation on FR-4 PCB at TL = +75°C and reverse leakage ≤0.1 µA at VR = 6.9 V. It serves as a precision voltage reference or overvoltage clamp in portable battery-powered sensor nodes.
For engineers reviewing the DDZ9696-7 datasheet, DDZ9696-7 pinout, DDZ9696-7 application, or DDZ9696-7 equivalent, key selection criteria include its low 50 µA test current suitability for ultra-low-power biasing, tight ±5% zener voltage tolerance, SOD123 footprint compatibility with automated assembly, and thermal resistance of 340°C/W (junction-to-ambient).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation under low-current conditions. Its specified 50 µA test current enables accurate voltage referencing in circuits where quiescent current must remain below 100 µA - critical for coin-cell–powered IoT endpoints and energy-harvesting subsystems.
The device exhibits a temperature coefficient of approximately +0.06%/°C near 9.1 V (per Fig. 17), enabling predictable drift compensation in ambient-temperature–varying environments. Its 150°C/W junction-to-lead thermal resistance supports reliable operation when soldered to thermally anchored copper pours.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1-7-F | Same 9.1 V nominal, but rated at 300 mW PD and 410°C/W RθJA; ±5% tolerance; SOT-23 package | Higher thermal resistance requires larger copper area; SOT-23 footprint incompatible with SOD123 land pattern | Select only if board redesign accommodates SOT-23 and thermal pad expansion is feasible |
| MMSZ5240B-7-F | 9.1 V nominal, 500 mW PD, but specified at 20 mA IZT; ±5% tolerance; SOD-123 package | 20 mA test current increases bias network load; higher dynamic impedance above 100 µA | Prefer for higher-current regulation; avoid in µA-level bias chains due to excessive IZT-induced error |
Compared with BZX84-C9V1-7-F and MMSZ5240B-7-F, DDZ9696-7 uniquely balances ultra-low 50 µA test current, SOD123 compatibility, and 500 mW rating-making it optimal for space-constrained, battery-critical systems where both footprint and quiescent current are design-limiting factors.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9696-7 guarantees IR ≤ 0.1 µA?
Per the Electrical Characteristics table, DDZ9696-7 specifies IR ≤ 0.1 µA at VR = 6.9 V. This value corresponds to the reverse voltage where leakage remains below the stated limit - not the breakdown voltage. Operation above 6.9 V enters the zener region, where controlled conduction begins at the nominal 9.1 V point.
Can DDZ9696-7 be used in automotive applications?
Yes - the automotive-grade variant DDZ9696Q-7 is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. The standard DDZ9696-7 is not automotive-qualified; use DDZ9696Q-7 for under-hood or safety-critical vehicle systems requiring change control and extended reliability validation.
What is the typical zener impedance (ZZT) of DDZ9696-7 at 50 µA?
While the datasheet does not list ZZT explicitly for DDZ9696-7, Fig. 12 shows typical zener impedance for DDZ9693–DDZ9699 at 1 mA and 5 mA. At 50 µA, impedance is significantly higher - estimated >10 kΩ based on curve extrapolation and the device's low-current design intent. For low-impedance regulation, operate near 1 mA or use a buffered reference.
Does DDZ9696-7 have a defined forward voltage specification?
Yes - the datasheet specifies VF = 0.9 V at IF = 10 mA (page 2, Maximum Ratings). This forward characteristic applies when the device is operated in forward conduction mode, such as in ESD protection configurations or dual-purpose clamp circuits. It is not intended for sustained forward conduction in normal operation.
