Product details
Overview
DDZ9698-7 from Diodes Incorporated is a surface-mount low-current Zener diode with nominal zener voltage 11 V (min 10.45 V, max 11.55 V), rated for 500 mW power dissipation on FR-4 PCB at TL = +75°C, and specified at low test current of 50 µA - ideal for precision voltage reference and low-bias battery-powered circuits in portable instrumentation and sensor signal conditioning.
For engineers reviewing the DDZ9698-7 datasheet, DDZ9698-7 pinout, DDZ9698-7 application, or DDZ9698-7 equivalent, this device serves as a stable, low-leakage (0.05 µA @ 8.4 V) voltage clamp in analog front-ends, power supply monitoring, and overvoltage protection where SOD123 footprint and thermal performance (RθJA = 340 °C/W) are critical design constraints.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its low 50 µA test current enables operation in ultra-low-power systems, while its ±5% zener voltage tolerance (10.45–11.55 V) supports precision regulation without external trimming.
Thermal design is enabled by its SOD123 package with RθJL = 150 °C/W and defined pad layout per Diodes Inc.'s Suggested Pad Layout document. The device exhibits a positive temperature coefficient (~+0.06 %/°C at 11 V), confirmed in Fig. 18, making it suitable for temperature-stable bias networks when paired with complementary negative-TC components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11LT1G | Same 11 V nominal, but rated at 350 mW (vs. 500 mW); higher IR (0.1 µA @ 8.4 V) | Limited to lower-power PCB layouts; less suitable for sustained 50 µA bias loads near thermal limit | Select if footprint compatibility with BZX84 family is required and power margin >150 mW is available |
| MMSZ4689-TP | 11 V nominal, 500 mW rating, but tighter VZ tolerance (±2.5%) and higher IZT (20 mA) | Requires current source redesign to deliver 20 mA; unsuitable for µA-level bias networks | Choose only when absolute VZ accuracy outweighs current consumption constraints |
Compared with BZX84-C11LT1G and MMSZ4689-TP, DDZ9698-7 uniquely balances 500 mW capability, 50 µA test current, and ±5% tolerance - making it optimal for space-constrained, battery-sensitive designs where thermal headroom and ultra-low bias current coexist.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9698-7 guarantees IR ≤ 0.05 µA?
Per the Electrical Characteristics table, DDZ9698-7 specifies IR = 0.05 µA at VR = 8.4 V. This is the maximum reverse voltage at which the leakage current is guaranteed not to exceed that value. Operation above 8.4 V enters the zener breakdown region, where current increases sharply per Fig. 3 and Fig. 5.
Can DDZ9698-7 be used in place of a 10 V Zener in a voltage reference circuit?
No - DDZ9698-7 has a nominal zener voltage of 11 V (10.45–11.55 V range). Substituting it for a 10 V part would shift the reference point by ≥0.45 V, potentially violating system accuracy specs. For 10 V, DDZ9697-7 (10.0 V nominal, 9.50–10.50 V range) is the correct variant in this series.
Is DDZ9698-7 qualified for automotive applications?
No - DDZ9698-7 is the standard-grade part. The automotive-qualified version is DDZ9698Q-7, which carries AEC-Q101 qualification, PPAP capability, and is manufactured in IATF 16949 certified facilities. The "Q" suffix is mandatory for automotive use.
What is the forward voltage drop (VF) of DDZ9698-7 at 10 mA?
Per the Maximum Ratings table, VF = 0.9 V at IF = 10 mA. This value applies only in forward conduction mode and is relevant for polarity-check circuits or ESD protection paths where the diode may conduct forward during fault conditions.
