Product details
Overview
DDZ9692S-7 from Diodes Incorporated is a surface-mount precision Zener diode with nominal Zener voltage 6.8 V (min 6.46 V, max 7.14 V), 50 µA test current, 0.1 µA reverse leakage at 5.1 V, and 200 mW power dissipation in SOD-323 package. It delivers sharp breakdown characteristics and tight ±5% VZ tolerance for voltage reference and regulation in low-power analog circuits.
For engineers reviewing the DDZ9692S-7 datasheet, DDZ9692S-7 pinout, DDZ9692S-7 application, or DDZ9692S-7 equivalent, key selection criteria include Zener voltage accuracy, low leakage at sub-breakdown bias, thermal resistance (625 °C/W), RoHS-compliant "Green" construction, and suitability for automated SMT assembly on FR-4 PCBs.
Technical Context
This device operates as a two-terminal voltage reference, maintaining stable reverse-biased conduction above its specified Zener voltage threshold. Its sharp breakdown and low dynamic impedance (typ. 15 Ω at IZ = 50 µA) enable high-accuracy regulation in feedback paths and sensing nodes.
The SOD-323 package supports high-density layout with cathode band polarity marking and matte tin terminals solderable per MIL-STD-202. Thermal performance is defined for JEDEC-standard pad layout, with derating to zero power at 150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.8 V nominal, 6.46–7.14 V range at IZT = 50 µA - ensures ±5% regulation accuracy under standard test conditions |
| Reverse Leakage (IR) | 0.1 µA max at VR = 5.1 V - enables ultra-low standby current in bias networks and precision dividers |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - defines maximum continuous DC power handling on standard FR-4 layout |
| Thermal Resistance (RθJA) | 625 °C/W - determines junction temperature rise per milliwatt; requires thermal-aware layout for >85 °C ambient |
| Operating Temperature | −65 to +150 °C - supports industrial and automotive under-hood applications with wide ambient variation |
| Capacitance (CT) | Typ. 25 pF at VR = 1 V - limits high-frequency noise coupling in RF-adjacent reference circuits |
Pinout & Package
Package: SOD-323 - surface-mount plastic case (UL 94V-0), 0.004 g weight, cathode band polarity marking, matte tin-plated Alloy 42 leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node | Connected to circuit common in shunt regulator configuration; establishes return path for Zener current |
| Cathode | Zener breakdown terminal / Regulated output node | Provides stable voltage relative to anode; used as reference point for error amplifiers or ADC references |
Key Features
| Feature | Design Value |
|---|---|
| Very sharp breakdown characteristics | Low dynamic impedance (15 Ω typ.) ensures minimal voltage shift across operating current range |
| Tight VZ tolerance (±5%) | Reduces need for post-assembly trimming in production calibration of analog sensor interfaces |
| Lead-free & RoHS-compliant | Meets global environmental compliance without requiring special Pb-free reflow profiles |
| Low leakage (0.1 µA) | Minimizes error in high-impedance voltage dividers and battery-powered reference circuits |
| Suitable for automated assembly | SOD-323 footprint and terminal finish support 0.3 mm pitch pick-and-place and standard reflow profiles |

FAQ
What is the maximum Zener test current for DDZ9692S-7?
The specified Zener test current (IZT) is 50 µA, per the Electrical Characteristics table. This current establishes the nominal 6.8 V Zener voltage and is used to define dynamic impedance and leakage parameters. Operation beyond this current is permissible up to the 200 mW power limit, but voltage regulation shifts due to self-heating and impedance nonlinearity.
Does DDZ9692S-7 have AEC-Q101 qualification?
No - DDZ9692S-7 is not AEC-Q101 qualified. Only DDZ9705S (marked with Note 5 in the datasheet) carries AEC-Q101 qualification for automotive-grade reliability. DDZ9692S-7 is rated for industrial temperature range (−65 to +150 °C) and RoHS compliance, but lacks stress-test validation for automotive use cases.
Can DDZ9692S-7 replace a 6.2 V Zener in an existing design?
No - DDZ9692S-7 has a nominal 6.8 V Zener voltage and is not a drop-in replacement for 6.2 V devices like DDZ9691S. Substituting it would raise regulated voltage by ~10%, potentially exceeding downstream IC absolute maximum ratings or altering feedback loop setpoints. Voltage-specific selection is mandatory.
What is the typical temperature coefficient of VZ for DDZ9692S-7?
Per Figure 17, the typical temperature coefficient for DDZ9692S-7 (6.8 V type) is −0.02 %/°C. This negative coefficient means VZ decreases slightly with rising temperature, enabling compensation when paired with positive-tempco components in precision references.
