Product details
Overview
DDZ9716T-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 39 V, ±5% tolerance (37.05–40.95 V), 150 mW power dissipation, 0.05 µA reverse leakage at 29.6 V, and SOD523 package. It provides precise voltage regulation in low-power biasing, reference, and overvoltage protection circuits for portable electronics and sensor interfaces.
For engineers reviewing the DDZ9716T-7 datasheet, DDZ9716T-7 pinout, DDZ9716T-7 application, or DDZ9716T-7 equivalent, key selection criteria include zener voltage accuracy, low leakage at rated VR, thermal resistance (833 °C/W), sharp breakdown characteristics, and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable voltage across its terminals under controlled current (IZT = 50 µA). Its sharp knee and low dynamic impedance support accurate regulation in low-current analog circuits.
Designed for thermal equilibrium at 30°C ±1°C during VZ measurement, it exhibits a positive temperature coefficient (~0.08 %/°C at 39 V) per Fig. 19, enabling predictable drift behavior in ambient temperature ranges from –65°C to +150°C.

Applications
| Portable Power Management | Sensor Signal Conditioning |
|---|---|
Use Scenario: Regulating bias voltage for low-power ADC reference buffers in wearables and IoT nodes. IC Role / Device Role / Timing Role: Zener diode providing stable 39 V reference for precision analog front-ends. Use Value: Low 0.05 µA leakage preserves battery life; ±5% VZ tolerance ensures consistent reference accuracy across production units. | Use Scenario: Clamping transient overvoltage on 3.3 V or 5 V sensor supply rails exposed to ESD or inductive coupling. IC Role / Device Role / Timing Role: Two-terminal overvoltage protector shunting excess energy to ground before IC damage occurs. Use Value: Sharp breakdown at 39 V allows safe margin above normal rail voltage while limiting peak clamped voltage. |

Use Scenario: Generating stable bias for 4–20 mA transmitter output stages operating from 24 V DC supplies. IC Role / Device Role / Timing Role: Zener-based shunt regulator establishing fixed headroom voltage for loop driver transistors. Use Value: 150 mW rating supports continuous operation at 24 V input with appropriate series resistor; 833 °C/W RθJA enables thermal stability on standard PCB copper. | Use Scenario: Providing isolated bias for LED side of high-speed optocouplers in PLC I/O modules. IC Role / Device Role / Timing Role: Precision voltage clamp ensuring consistent LED forward current despite supply ripple. Use Value: Tight 37.05–40.95 V range maintains constant optical output; low leakage avoids unintended turn-on during signal transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C39 | Same 39 V nominal, ±5% tolerance, but SOD323 package (larger footprint, 200 mW rating) | Higher power handling suits higher-current regulation; less space-efficient than SOD523 | Select when >150 mW dissipation or legacy SOD323 layout compatibility is required |
| MMSZ4702T1G | 39 V nominal, ±5%, SOD123 package (3.7 × 1.6 mm), 500 mW rating, 1 µA leakage @ 31.2 V | Higher leakage and larger size; better for high-reliability industrial use with wider thermal margin | Choose where board space is not constrained and higher power margin or AEC-Q200 qualification is needed |
Compared with BZX584-C39 and MMSZ4702T1G, DDZ9716T-7 offers the smallest footprint (SOD523), lowest leakage (0.05 µA), and tightest thermal profile for ultra-compact, low-quiescent designs-making it optimal for space- and power-sensitive portable applications.

FAQ
What is the maximum reverse voltage (VR) at which DDZ9716T-7 guarantees ≤0.05 µA leakage?
Per the Electrical Characteristics table, DDZ9716T-7 specifies 0.05 µA maximum reverse leakage current at VR = 29.6 V - 76% of its nominal 39 V zener voltage. This value is measured under short-duration pulse conditions to minimize self-heating, ensuring reliable low-leakage performance in static bias applications.
Can DDZ9716T-7 be used in place of a 36 V or 43 V Zener diode?
No - DDZ9716T-7 is specifically rated for 39 V nominal zener voltage (37.05–40.95 V range). Substituting it for 36 V (DDZ9715T) or 43 V (DDZ9717T) devices would result in incorrect regulation or clamping levels. Each part in the DDZ9689T–DDZ9717T family has unique type code (MN for DDZ9716T) and tested VZ range; cross-voltage substitution is not supported.
Is the SOD523 package of DDZ9716T-7 compatible with standard 0402 reflow profiles?
Yes - the SOD523 package (1.2 × 0.8 mm) is dimensionally aligned with JEDEC-standard 0402 footprints and qualified for reflow soldering per J-STD-020D Level 1 moisture sensitivity. Its matte tin annealed terminals meet MIL-STD-202 Method 208 solderability requirements, supporting compatibility with common lead-free reflow profiles.
Does DDZ9716T-7 have AEC-Q200 qualification for automotive use?
No - DDZ9716T-7 is not AEC-Q200 qualified. While its operating temperature range (–65°C to +150°C) overlaps with automotive requirements, Diodes Incorporated does not list this part in its AEC-Q200-certified portfolio. For automotive applications, consult Diodes' AEC-Q200-qualified Zener families such as the BZT52 series.
