Product details
Overview
DDZ9713T-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 30 V, tolerance ±5% (28.5–31.5 V), maximum power dissipation 150 mW, and ultra-low reverse leakage current of 50 nA at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning and power rail monitoring circuits.
For engineers reviewing the DDZ9713T-7 datasheet, DDZ9713T-7 pinout, DDZ9713T-7 application, or DDZ9713T-7 equivalent, key selection criteria include zener voltage accuracy, temperature coefficient (±0.04 %/°C typical at 30 V), SOD523 package footprint compatibility, and low leakage performance under standby bias conditions.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its sharp knee characteristics and low dynamic impedance (≈120 Ω at IZ = 5 mA) enable accurate regulation in space-constrained, low-current applications.
The SOD523 package supports high-density PCB layouts and automated placement, while its thermal resistance (RθJA = 833 °C/W on FR-4) requires derating above +25°C ambient-e.g., 100 mW max at +75°C per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V nominal, 28.5–31.5 V range at IZT = 5 mA - defines regulated output level with ±5% initial tolerance |
| Power Dissipation (PD) | 150 mW at TA = +25°C - limits continuous current to ~5 mA for stable regulation without thermal runaway |
| Reverse Leakage (IR) | 50 nA max at VR = 22.8 V - ensures minimal quiescent current draw in battery-powered sensing nodes |
| Zener Impedance (ZZT) | ≈120 Ω at IZ = 5 mA - determines output voltage deviation under small load transients |
| Temperature Coefficient | ±0.04 %/°C typical at 30 V - enables predictable drift compensation in industrial temperature ranges (−40°C to +85°C) |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - relevant for polarity verification and ESD protection path design |
Pinout & Package
Package: SOD523 - ultra-small plastic surface-mount case (0.80 mm × 1.20 mm × 0.60 mm), cathode marked by band on top surface, matte tin-plated alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential node in zener operation | Used for polarity identification during visual inspection and automated optical alignment |
| Cathode | Current exit terminal in forward bias; connected to higher-potential node in zener operation | Marked by visible band; must be tied to regulated voltage rail or reference point in clamp configuration |
Key Features
| Feature | Design Value |
|---|---|
| Sharp breakdown knee | Enables precise voltage clamping at 30 V with minimal overshoot during transient events |
| Low leakage current | 50 nA max at 76% of VZ preserves battery life in always-on sensor interfaces |

Applications
| Industrial Sensor Signal Conditioning | USB-C Power Delivery Monitoring |
|---|---|
Use Scenario: Stabilizing reference voltage for 16-bit ADCs measuring thermocouple or strain gauge outputs in factory automation modules. IC Role / Device Role / Timing Role: Precision shunt voltage reference providing 30 V bias to op-amp gain stages and ADC input dividers. Use Value: ±5% VZ tolerance and <±0.04 %/°C TC ensure <0.3% full-scale error over −25°C to +70°C operating range. | Use Scenario: Clamping auxiliary power rail (VCONN) in USB-C receptacles to prevent overvoltage damage during hot-plug events. IC Role / Device Role / Timing Role: Fast-response overvoltage protector placed between VCONN and ground, triggered at 30 V threshold. Use Value: 50 nA leakage avoids loading the 1–5 V VCONN line during idle states; sharp knee limits clamping overshoot to <32 V. |
| IoT Node Battery Voltage Supervision | Programmable Logic Controller (PLC) Input Protection |
Use Scenario: Monitoring Li-ion battery pack voltage (nominal 24 V) in edge AI gateways to trigger low-battery alerts before shutdown. IC Role / Device Role / Timing Role: Zener-based comparator reference feeding into a microcontroller's analog watchdog input. Use Value: 150 mW rating permits direct connection to battery via 100 kΩ resistor, eliminating need for active supervision circuitry. | Use Scenario: Protecting 24 V DC digital input channels in industrial PLCs against field-wiring surges and miswiring. IC Role / Device Role / Timing Role: Primary shunt clamp limiting input voltage to 30 V before downstream optocoupler or Schmitt trigger. Use Value: SOD523 size fits dense I/O module layouts; 833 °C/W RθJA allows safe energy absorption during 100 ns–1 µs transients per IEC 61000-4-4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C30LT1G | Same 30 V nominal, ±5% tolerance, but SOD-323 package (1.7 mm × 1.3 mm); ZZT ≈ 90 Ω | Larger footprint; higher thermal mass improves surge handling but reduces board density | Select when higher pulse power capability (>200 mW peak) is required and board space permits larger package |
| MMSZ5257ET1G | 30 V nominal, ±5%, SOD-123 package (3.7 mm × 1.6 mm); PD = 500 mW; IR = 100 nA at 24 V | Higher power rating suits higher-current regulation; less suitable for ultra-low-leakage designs | Choose for applications needing >10 mA regulation current or legacy SOD-123 footprint compatibility |
Compared with BZX584C30LT1G and MMSZ5257ET1G, DDZ9713T-7 offers the smallest footprint and lowest leakage among 30 V Zeners, making it optimal for miniaturized, battery-sensitive designs where regulation current stays below 5 mA.

FAQ
What is the maximum reverse voltage that can be continuously applied to DDZ9713T-7 without breakdown?
The maximum non-breakdown reverse voltage is 22.8 V, specified as VR in the Electrical Characteristics table. At this voltage, reverse leakage remains ≤50 nA. Exceeding 22.8 V risks entering the zener breakdown region, where controlled conduction begins at the rated 30 V nominal point.
Can DDZ9713T-7 be used in parallel for higher power dissipation?
No-parallel connection is not recommended due to mismatch in zener voltage tolerances (±5%) and temperature coefficients, which cause uneven current sharing and potential thermal runaway. For higher power, select a single higher-rated Zener (e.g., MMSZ5257ET1G) or use an active regulator.
Is the SOD523 package compatible with standard reflow soldering profiles?
Yes-the SOD523 package is rated for moisture sensitivity Level 1 per J-STD-020D and uses matte tin annealed terminations compliant with MIL-STD-202, Method 208. It supports standard lead-free reflow profiles (peak 260°C, 60–90 sec above 217°C) without popcorn or delamination.
How does the temperature coefficient affect regulation accuracy over −40°C to +125°C?
At 30 V, the typical TC is ±0.04 %/°C. Over a 165°C span, worst-case drift is ±6.6 V (0.04 × 165), but actual variation is nonlinear and bounded by Fig. 19: measured data shows <±2.5 V shift from −40°C to +125°C, confirmed by characterization across the DDZ9713T–DDZ9717T group.
