Product details
Overview
DDZ9716S-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal Zener voltage 39 V, ±5% tolerance (37.05–40.95 V), 200 mW power dissipation, 0.05 μA maximum reverse leakage at 29.6 V, and SOD-323 package. It provides stable voltage reference in low-power analog circuits, power supply feedback loops, and overvoltage protection for microcontroller I/O pins.
For engineers reviewing the DDZ9716S-7 datasheet, DDZ9716S-7 pinout, DDZ9716S-7 application, or DDZ9716S-7 equivalent, key selection criteria include Zener voltage accuracy, temperature coefficient (≈+0.08%/°C per Fig. 20), low leakage at rated VR, thermal resistance (625 °C/W), and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining a stable reverse-biased breakdown voltage across its cathode–anode terminals under controlled current conditions (IZT = 50 μA). Its sharp knee breakdown and tight VZ tolerance enable high-accuracy referencing without external trimming.
Designed for thermal equilibrium at 30°C ±1°C during VZ measurement, it exhibits a positive temperature coefficient (~+0.08%/°C) typical for 39 V Zeners (Fig. 20), ensuring predictable drift in ambient temperature variations from –65°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Nom/Min/Max) | 39 V / 37.05 V / 40.95 V - defines precise clamping threshold for voltage regulation or protection |
| Test Current (IZT) | 50 μA - standard bias point for guaranteed VZ specification and impedance characterization |
| Max Reverse Leakage (IR @ VR) | 0.05 μA @ 29.6 V - ensures minimal standby current in high-impedance reference nodes |
| Power Dissipation (PD) | 200 mW - limits continuous Zener current to ≤5.1 mA at 39 V in still air |
| Thermal Resistance (RθJA) | 625 °C/W - requires derating above 25°C ambient; full power only at TA ≤ 25°C |
| Operating Temperature | –65°C to +150°C - supports industrial and automotive under-hood applications |
| Total Capacitance | ≈1.5 pF @ 2 V (Fig. 10) - negligible loading in high-frequency reference or signal-clamping paths |
Pinout & Package
Package: SOD-323 - ultra-small plastic surface-mount case (2.30–2.70 mm length, 1.20–1.40 mm width, 0.25–0.35 mm thickness), RoHS-compliant, matte tin-plated terminals, cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink terminal in forward bias; reference ground node in reverse bias | Connected to system ground or lower-potential rail when used as shunt regulator |
| Cathode | Current source terminal in reverse breakdown; voltage reference output | Provides stable 39 V relative to anode; marked with visible band on package top view |
Key Features
| Feature | Design Value |
|---|---|
| Very sharp breakdown knee | Enables clean transition into regulation with minimal voltage hysteresis at IZT |
| Tight VZ tolerance (±5%) | Reduces need for post-assembly calibration in precision reference designs |
| Low leakage (0.05 μA @ 29.6 V) | Preserves battery life and signal integrity in high-impedance sensor interface circuits |
| SOD-323 footprint | Supports high-density PCB layouts and compatibility with standard 0805 reflow profiles |
| Lead-free & "Green" construction | Meets RoHS Directive 2011/65/EU and Diodes Inc.'s halogen-free material policy |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller I/O Protection |
|---|---|
Use Scenario: Stabilizing excitation voltage for bridge-based pressure sensors in factory automation systems. IC Role / Device Role / Timing Role: Shunt voltage reference providing 39 V bias to Wheatstone bridge, regulated against 24 V supply rail fluctuations.

Use Value: Limits peak stress on MCU GPIO to <40 V while drawing <0.1 μA in normal operation, preserving input leakage specs. |
| Programmable Power Supply Feedback | Calibration Reference for Data Acquisition |
Use Scenario: Setting output voltage of isolated DC-DC converter via optocoupler feedback loop. IC Role / Device Role / Timing Role: Precision Zener in TL431-like configuration, generating stable 39 V reference for error amplifier comparison. Use Value: Enables ±1% output regulation over line/load/temperature with no external trim potentiometer. | Use Scenario: Providing known reference voltage for ADC offset/gain calibration in portable test equipment. IC Role / Device Role / Timing Role: Low-drift voltage source connected to multiplexer input channel during self-calibration sequence.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C39LT1G | VZ = 39 V ±5%, same SOD-323, but RθJA = 500 °C/W and IR = 0.1 μA @ 29.6 V | Higher leakage may affect ultra-low-power sensor references; better thermal performance allows marginally higher IZ | Select when board layout permits slightly higher power handling and leakage is not critical |
| MMSZ4702T1G | VZ = 39 V ±5%, SOD-123 package (larger), PD = 500 mW, IR = 0.1 μA @ 29.6 V | Larger footprint and higher power rating suit higher-current regulation; incompatible with SOD-323 land pattern | Select when >200 mW dissipation is required or legacy SOD-123 layout is fixed |
Compared with BZX84-C39LT1G and MMSZ4702T1G, DDZ9716S-7 offers the lowest leakage and strictest thermal design constraints within the smallest footprint-making it optimal for space-constrained, battery-sensitive, and high-accuracy reference designs where 200 mW suffices.

FAQ
What is the recommended PCB pad layout for DDZ9716S-7?
The official suggested pad layout is documented in Diodes Incorporated Application Note AP02001. It specifies copper land dimensions matching SOD-323 outline tolerances (C = 2.40 mm, B = 1.25 mm), thermal relief for cathode/anode pads, and minimum solder mask clearance to prevent bridging. Use this layout to ensure reliable reflow soldering and thermal performance.
Does DDZ9716S-7 meet AEC-Q101 qualification?
No-DDZ9716S-7 is not AEC-Q101 qualified. While the related DDZ9705S (18 V variant) is explicitly noted as AEC-Q101 qualified in the datasheet (Note 5), DDZ9716S-7 appears only in the general electrical characteristics table without reliability qualification statements. For automotive applications, consider AEC-Q101 alternatives like BZX84-C39LT1G.
How does temperature affect the Zener voltage of DDZ9716S-7?
Per Figure 20, DDZ9716S-7 exhibits a positive temperature coefficient of approximately +0.08%/°C near 39 V. This means VZ increases by ~31 mV per 10°C rise above 25°C ambient. The effect is linear and predictable, enabling compensation in high-precision applications using simple polynomial correction.
Can DDZ9716S-7 be used in forward-bias applications?
Yes-it functions as a standard silicon diode in forward bias with VF = 0.9 V at IF = 10 mA (per Maximum Ratings table). However, its primary design intent and characterized specifications are for reverse-bias Zener operation; forward conduction is secondary and lacks detailed characterization beyond VF and thermal limits.
