Product details
Overview
DDZ9698S-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal Zener voltage 11 V (min 10.45 V, max 11.55 V), 50 µA test current, and 0.05 µA reverse leakage at 8.4 V. Packaged in SOD-323, it delivers tight ±5% tolerance, low thermal resistance (625 °C/W), and RoHS-compliant lead-free construction for voltage reference and regulation in space-constrained analog circuits.
For engineers reviewing the DDZ9698S-7 datasheet, DDZ9698S-7 pinout, DDZ9698S-7 application, or DDZ9698S-7 equivalent, key selection criteria include Zener voltage accuracy at IZT = 50 µA, temperature coefficient behavior near 11 V, SOD-323 footprint compatibility, and low leakage performance below 10 V reverse bias.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining stable output by conducting reverse current above its specified breakdown threshold. Its sharp knee characteristic and low dynamic impedance (< 40 Ω at 50 µA) enable precise regulation in low-power feedback loops and trimming circuits.
The SOD-323 package supports automated placement and reflow soldering, while the 0.004 g mass and UL 94V-0 molding compound meet stringent reliability requirements for consumer and industrial PCBs. Thermal derating begins at 25°C ambient, with full 200 mW dissipation only achievable at TA ≤ 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.0 V nominal, 10.45–11.55 V range at IZT = 50 µA - defines stable reference point for analog sensing and supply monitoring |
| Reverse Leakage (IR) | 0.05 µA max at VR = 8.4 V - ensures minimal error current in high-impedance bias networks |
| Power Dissipation (PD) | 200 mW at TA = 25°C - limits maximum continuous Zener current to ~18 mA at 11 V |
| Thermal Resistance (RθJA) | 625 °C/W on FR-4 board - requires thermal pad design if operating above 50 mW ambient |
| Package | SOD-323 - 1.2–1.4 mm width, 2.3–2.7 mm length, 0.25–0.35 mm thickness - fits 0805-class footprints with cathode band polarity marking |
| Temperature Coefficient | ≈ +0.07 %/°C near 11 V (inferred from Fig. 18) - contributes < ±0.8% drift over –40°C to +85°C operating range |
Pinout & Package
SOD-323 package: two-terminal surface-mount device with cathode identified by molded band; no internal die bonding wires or multi-pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node | Connected to circuit common; establishes reference potential when cathode is biased above anode |
| Cathode | Zener breakdown terminal / Regulated output node | Applied to regulated rail; conducts reverse current to clamp voltage at VZ when input exceeds threshold |
Key Features
| Feature | Design Value |
|---|---|
| Sharp breakdown knee | Enables stable regulation at low test currents (50 µA), reducing quiescent power in battery-powered references |
| Tight VZ tolerance | ±5% (10.45–11.55 V) eliminates need for post-assembly trimming in mid-accuracy applications |
| Low leakage current | 0.05 µA at 8.4 V allows use in >100 MΩ feedback networks without significant voltage error |
| RoHS-compliant & "Green" | Matte tin finish over Alloy 42 leadframe meets J-STD-020 Level 1 moisture sensitivity and halogen-free requirements |
| Automated assembly ready | SOD-323 outline and 0.004 g weight ensure reliable pick-and-place yield on high-speed SMT lines |
Applications
| ADC Reference Buffer | Power Supply Monitor |
|---|---|
|
Use Scenario: Stabilizing reference voltage for 12-bit SAR ADC in portable instrumentation. IC Role / Device Role / Timing Role: Shunt reference providing fixed 11 V node to buffer amplifier input. Use Value: 0.05 µA leakage introduces < 0.5 LSB error in 1 MΩ input impedance buffer stage at 25°C. |
Use Scenario: Detecting brown-out condition in 12 V automotive accessory rail. IC Role / Device Role / Timing Role: Threshold detector comparing rail voltage against 11 V Zener-clamped comparator input. Use Value: Sharp 11 V breakdown enables clean 1 V hysteresis window with standard resistor divider scaling. |
| Current Source Bias | Overvoltage Clamp |
|
Use Scenario: Setting bias current for low-noise op-amp input stage in audio preamplifier. IC Role / Device Role / Timing Role: Stable voltage source across emitter degeneration resistor to fix transistor IC. Use Value: ±5% VZ tolerance yields ±5% current accuracy-sufficient for gain-setting without calibration. |
Use Scenario: Protecting microcontroller I/O pin from transient spikes on 12 V sensor interface line. IC Role / Device Role / Timing Role: Fast-acting clamp limiting pin voltage to 11.6 V during ESD events. Use Value: Low dynamic impedance (< 40 Ω) ensures clamping within 10 ns of overvoltage onset per typical Zener response data. |
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 ±6% tolerance (10.4–11.6 V); higher 100 µA leakage at 8.4 V | Less suitable for low-leakage bias networks; acceptable for general-purpose clamping | Select when cost priority outweighs leakage and tolerance requirements |
| MMSZ5240B-TP | 10 V nominal (not 11 V); ±5% tolerance; 0.1 µA leakage at 7.6 V | Requires circuit redesign for 11 V reference; better for 10 V systems with tighter thermal drift | Choose only if system architecture permits 10 V reference shift and lower leakage is critical |
Compared with BZX84-C11LT1G and MMSZ5240B-TP, DDZ9698S-7 offers superior leakage control and exact 11 V targeting-making it optimal for precision analog feedback where reference stability directly impacts measurement fidelity.

FAQ
What is the maximum Zener test current for DDZ9698S-7?
The device is characterized at IZT = 50 µA, with maximum continuous Zener current limited by power dissipation: at 11 V, PD = 200 mW implies IZ(max) ≈ 18.2 mA at TA = 25°C. Derating applies above 25°C per Figure 1.
Does DDZ9698S-7 have a specified Zener impedance?
Yes-typical dynamic impedance is 40 Ω at IZ = 50 µA and 25°C (inferred from Figure 12 curve for 11–12 V devices), confirming suitability for low-noise reference applications requiring stable regulation under varying load conditions.
Is the SOD-323 package compatible with standard reflow profiles?
Yes-the device meets J-STD-020 Level 1 moisture sensitivity and is qualified for standard Pb-free reflow profiles (peak 260°C, 10–30 sec), with recommended pad layout available in Diodes' AP02001 application note.
Can DDZ9698S-7 be used in automotive applications?
While not AEC-Q101 qualified itself, DDZ9698S-7 shares construction and testing with AEC-Q101–qualified variants in the same family (e.g., DDZ9705S), and is commonly deployed in non-safety-critical automotive subsystems such as infotainment power sequencing and sensor signal conditioning.
