Product details
Overview
DDZ9696S-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal Zener voltage 9.1 V, ±5% tolerance (8.65–9.56 V), 50 µA maximum reverse leakage at 6.9 V, 200 mW power dissipation, and SOD-323 package - used for voltage regulation and reference in low-power analog circuits, sensor biasing, and ADC reference stabilization.
For engineers reviewing the DDZ9696S-7 datasheet, DDZ9696S-7 pinout, DDZ9696S-7 application, or DDZ9696S-7 equivalent, this page delivers verified electrical specs, thermal derating behavior, Zener impedance profile, temperature coefficient, and RoHS-compliant packaging details essential for precision analog design and high-reliability board-level integration.
Technical Context
This Zener diode operates in reverse breakdown with sharp knee characteristics and tight VZ tolerance, enabling stable reference generation under low-current conditions (IZT = 50 µA). Its low leakage (0.1 µA at VR = 6.9 V) and predictable TC (≈+0.04 %/°C near 9.1 V, per Fig. 17) support accuracy-critical functions in battery-powered instrumentation.
The device uses an alloy-42 leadframe with matte tin annealing, rated for moisture sensitivity Level 1, and achieves RθJA = 625 °C/W on FR-4 with recommended pad layout. It is not AEC-Q101 qualified (unlike DDZ9705S), but meets industrial temperature range (–65 to +150 °C) and green compound requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Nom) | 9.1 V - precise reference point for 9 V rail regulation or comparator threshold setting |
| Zener Voltage Range | 8.65–9.56 V - ±5% tolerance ensures predictable clamping across production lots |
| Test Current (IZT) | 50 µA - low-current operation enables use in micropower sensor interfaces |
| Max Reverse Leakage (IR) | 0.1 µA @ 6.9 V - minimal error contribution in high-impedance reference dividers |
| Power Dissipation | 200 mW - limits maximum Zener current to ~22 mA at 9.1 V without heatsinking |
| Zener Impedance (ZZT) | ~150 Ω @ 50 µA (Fig. 12) - defines output impedance affecting load regulation in shunt references |
| Temp. Coefficient (TCVZ) | +0.04 %/°C (typ. near 9.1 V, Fig. 17) - low drift supports <±10 mV variation over –40 to +85 °C |

Applications
| ADC Reference Stabilization | Microcontroller Reset Threshold |
|---|---|
Use Scenario: Providing stable 9.1 V reference to external ADC's VREF pin in a 12-bit data acquisition module operating from a noisy 12 V supply. IC Role / Device Role / Timing Role: Shunt voltage reference regulating VREF against supply ripple and load transients. Use Value: Maintains <±0.5 LSB INL error over temperature due to low TCVZ and minimal self-heating at 50 µA bias. |
Use Scenario: Generating a precise reset threshold for an ARM Cortex-M0+ MCU powered from a 9.5 V LDO, where reset must assert below 8.8 V. IC Role / Device Role / Timing Role: Zener-based comparator input reference defining brown-out detection level. Use Value: Tight 8.65–9.56 V VZ range ensures deterministic reset activation without margin stacking. |
| Sensor Biasing Network | Overvoltage Clamp for RS-485 Transceiver |
Use Scenario: Biasing a silicon photodiode in photovoltaic mode within a handheld spectrometer, requiring stable 9.1 V reverse bias. IC Role / Device Role / Timing Role: Precision DC bias source delivering low-noise, low-drift voltage to photodiode cathode. Use Value: Sub-µA leakage prevents dark current corruption; sharp knee avoids bias droop during transient photocurrent surges. |
Use Scenario: Protecting RS-485 transceiver inputs (e.g., MAX13487) against ESD-induced transients up to ±15 kV on 12 V bus lines. IC Role / Device Role / Timing Role: Fast-acting shunt clamp limiting common-mode voltage excursion to ≤9.6 V. Use Value: Sharp breakdown onset ensures clamping begins before transceiver damage threshold (typically 13.2 V) is exceeded. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1 | Same 9.1 V nominal, ±5% tolerance, but SOT-23 package (larger footprint, RθJA ≈ 300 °C/W) | Higher power handling (350 mW) but less suitable for ultra-dense layouts | Select when higher surge current capability or legacy SOT-23 compatibility is required |
| MMSZ5240B | 9.1 V nominal, ±5%, but wider VZ spread (8.65–9.55 V), higher leakage (1 µA @ 7 V), SOD-123 package | Lower cost, but reduced accuracy and stability in precision references | Select for non-critical biasing where cost outweighs 10× leakage penalty |
Compared with BZX84-C9V1 and MMSZ5240B, DDZ9696S-7 offers superior leakage performance (0.1 µA vs. ≥1 µA), tighter thermal resistance control in SOD-323, and sharper knee - making it preferred for micropower, space-constrained, and high-accuracy analog reference designs.

FAQ
What is the maximum continuous Zener current for DDZ9696S-7 at 25°C ambient?
The device has a 200 mW power rating and nominal VZ of 9.1 V, yielding a theoretical max continuous IZ of ~22 mA at 25°C. However, thermal derating applies above 25°C - Fig. 1 shows linear reduction to zero at 150°C, so sustained operation above 15 mA requires careful PCB thermal design.
Does DDZ9696S-7 have AEC-Q101 qualification?
No. DDZ9696S-7 is not AEC-Q101 qualified. Only DDZ9705S and higher-numbered parts in this family (e.g., DDZ9707S onward) are explicitly listed as AEC-Q101 qualified in the datasheet notes. This part meets industrial-grade reliability but lacks automotive stress-test validation.
How does the Zener impedance affect its performance in a shunt regulator?
Zener impedance (ZZT ≈ 150 Ω at 50 µA, per Fig. 12) directly impacts regulation accuracy: a 1 mA load change causes ~150 mV output shift. For stable regulation, keep dynamic load current variation below ±100 µA or add series resistance to limit sensitivity to ZZT.
Can DDZ9696S-7 be used in forward-bias applications?
Yes - its forward voltage is 0.9 V at 10 mA (per datasheet), matching standard silicon diode behavior. However, it is optimized for reverse breakdown; forward conduction is only specified for polarity verification and should not be relied upon for rectification or switching due to lack of rated IF parameters beyond 10 mA.
