Product details
Overview
DDZ9690-7 from Diodes Incorporated is a surface-mount low-current Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C, with nominal zener voltage of 5.6 V (min 5.32 V, max 5.88 V) at 50 µA test current, and reverse leakage current of 2 µA at 4 V. It is optimized for low-bias, battery-powered applications requiring stable reference voltage under light-load conditions.
For engineers reviewing the DDZ9690-7 datasheet, DDZ9690-7 pinout, DDZ9690-7 application, or DDZ9690-7 equivalent, this part serves as a precision low-power voltage reference in portable instrumentation, sensor biasing, and microcontroller reset circuitry where thermal stability and minimal quiescent current are critical.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals. Its specified test current of 50 µA enables accurate regulation in ultra-low-power circuits without significant loading on source rails.
Thermal resistance junction-to-lead is 150 °C/W, and junction-to-ambient is 340 °C/W on FR-4 PCB with standard pad layout - enabling predictable derating in compact layouts. Temperature coefficient of zener voltage is approximately +0.04 %/°C near 5.6 V, supporting moderate ambient variation tolerance.

IC Role / Device Role / Timing Role: Functions as voltage monitor in RC-based reset generator, triggering reset below 4.5 V. Use Value: 2 µA leakage at 4 V guarantees negligible current drain during brown-out detection, extending battery life. |
| Low-Power Reference Supply | ESD Protection Clamp |
|
Use Scenario: Creating local 5.6 V reference rail for precision comparators in energy-harvesting nodes. IC Role / Device Role / Timing Role: Shunt regulator maintaining stable voltage despite variable input from piezoelectric or solar harvesters. Use Value: 500 mW power rating allows brief transient absorption while sustaining regulation under intermittent load. |

IC Role / Device Role / Timing Role: Zener diode placed between signal and ground to limit voltage excursion during HBM events. Use Value: Low capacitance (<2 pF typical at 1 MHz) avoids signal integrity degradation in DC-coupled paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 (ON Semiconductor) | Same 5.6 V nominal, but rated for 300 mW and uses SOT-23 package; higher VF (0.9 V vs. 0.85 V typical) | Higher thermal resistance (RθJA ≈ 450 °C/W) limits power handling in dense layouts | Select if SOT-23 footprint is required and power demand stays below 300 mW |
| MMSZ5232BS (Vishay) | 5.6 V nominal, 500 mW rating, SOD-123 package, but specified at 20 mA IZT - higher dynamic impedance at low current | Less suitable for micropower designs due to higher minimum operating current requirement | Prefer for higher-current reference applications where 20 mA bias is available |
Compared with BZX84-C5V6 and MMSZ5232BS, DDZ9690-7 offers superior low-current regulation fidelity at 50 µA and identical SOD123 thermal performance, making it optimal for battery-constrained systems demanding both precision and minimal quiescent draw.

FAQ
What is the maximum power dissipation of DDZ9690-7 under standard PCB conditions?
DDZ9690-7 is rated for 500 mW power dissipation when mounted on an FR-4 PCB with minimum recommended pad layout at a lead temperature (TL) of +75°C. Derating begins above this temperature at 3.33 mW/°C based on RθJA = 340 °C/W, ensuring safe operation up to +150°C junction temperature.
Can DDZ9690-7 be used as a voltage reference in precision analog circuits?
Yes - its tight 5% zener voltage tolerance (5.32–5.88 V), low 50 µA test current, and low temperature coefficient (~+0.04 %/°C) make it suitable for non-critical precision references in sensor signal chains and comparator thresholds where absolute accuracy within ±0.3 V is acceptable.
Is DDZ9690-7 suitable for automotive applications?
No - the standard DDZ9690-7 variant is not AEC-Q101 qualified. For automotive use, Diodes Incorporated offers the DDZ9690Q-7 variant, which is manufactured in IATF 16949-certified facilities and supports PPAP documentation and change control requirements.
How does the SOD123 package affect thermal performance compared to SOT-23?
The SOD123 package provides lower thermal resistance to lead (RθJL = 150 °C/W) than typical SOT-23 Zeners (~200–250 °C/W), enabling better heat transfer to PCB copper. This results in higher sustained power capability on standard FR-4 layouts without thermal vias or large copper areas.
