Product details
Overview
AZ23C6V8-7 from Diodes Incorporated is a dual common-anode 300 mW surface-mount Zener diode with nominal zener voltage 6.8 V (6.4–7.2 V range), 8.0 Ω typical zener impedance at 5 mA, +0.045 %/°C temperature coefficient, and 3.0 V minimum reverse voltage at 0.1 µA leakage. It provides precision voltage reference and overvoltage clamping in compact SOT23 packaging for space-constrained power management circuits.
For engineers reviewing the AZ23C6V8-7 datasheet, AZ23C6V8-7 pinout, AZ23C6V8-7 application, or AZ23C6V8-7 equivalent, this dual-Zener device supports tight-tolerance voltage regulation, low-drift biasing, and dual-rail protection in industrial sensor interfaces, automotive body control modules, and portable battery-powered systems where thermal stability and dual-channel symmetry are critical.
Technical Context
This dual Zener operates in common-anode configuration, enabling independent cathode connections for two matched breakdown paths sharing one anode terminal. Its ±5% matching between diodes ensures balanced clamping across split-rail supplies or differential reference generation.
The device meets AEC-Q101 qualification (HBM ESD 8 kV, MM 400 V) and JEDEC high-reliability standards, with thermal resistance RθJA = 417 °C/W on FR-4 board and operating temperature range of –65 °C to +150 °C - suitable for under-hood and industrial ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 6.4–7.2 V at IZT = 5 mA - defines stable regulation window for mid-range voltage references |
| Zener Impedance | 8.0 Ω typical at 5 mA - ensures minimal output voltage shift under load variation |
| Temperature Coefficient | +0.045 %/°C - enables predictable, low-drift behavior above 25 °C ambient |
| Power Dissipation | 300 mW - supports continuous operation up to ~44 mA at 6.8 V without derating below 70 °C |
| Reverse Leakage | ≤0.1 µA at 3.0 V - guarantees negligible standby current in high-impedance bias networks |
| Thermal Resistance | 417 °C/W - requires careful PCB copper area design to maintain junction temp <150 °C |
Pinout & Package
Package: SOT23 - surface-mount plastic package with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rating, and 0.008 g weight.

| Cathode 2 (Pin 3) | Zener 2 Cathode | Second independent regulated node; enables dual-voltage generation or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zeners, Common Anode | Enables compact dual-rail referencing or mirrored clamping without discrete pairing |

Applications
| Industrial Sensor Signal Conditioning | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Precision voltage reference for 12-bit ADC front-end in temperature/humidity transmitters. IC Role / Device Role: Dual-rail Zener reference source providing stable 6.8 V and grounded anode for ratiometric scaling. Use Value: Matches channel-to-channel gain error tolerance (≤0.5%) via ≤5% VZ matching and low TC drift. |
Use Scenario: Overvoltage clamp on LIN bus transceiver supply rail in door module ECUs. IC Role / Device Role: Dual Zener protects both VCC and ground-referenced signal lines from load-dump transients. Use Value: Withstands 8 kV HBM ESD and maintains clamping threshold within 6.4–7.2 V across –40 to +125 °C. |
| Portable Medical Pulse Oximeter | Smart Home Hub Power Sequencing |
Use Scenario: Bias voltage generator for red/IR LED drivers powered by single-cell Li-ion (3.0–4.2 V). IC Role / Device Role: Generates stable 6.8 V reference using charge-pump boost stage, regulated by common-anode dual Zener. Use Value: Low 8.0 Ω ZZT minimizes dropout under pulsed LED loads; 300 mW rating supports intermittent 50 mA peaks. |
Use Scenario: Independent enable thresholds for 3.3 V and 5.0 V LDOs during cold-start sequencing.

Use Value: Tight VZ matching ensures ≤100 mV timing skew between rail enables, meeting USB PD compliance margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8 | Single Zener, same 6.8 V rating and SOT23 package, but no dual-element topology or VZ matching spec | Requires two separate devices for dual-rail use, increasing board area and mismatch risk | Select when only one regulated node is needed or layout allows discrete duplication |
| DZ23C6V8 | Common-cathode dual Zener variant (vs. AZ23's common-anode); identical VZ, ZZT, and thermal specs | Suitable for applications requiring cathode-referenced clamping (e.g., positive rail monitoring) | Choose based on circuit topology: common-anode for ground-referenced dual outputs, common-cathode for VCC-referenced dual inputs |
Compared with BZX84-C6V8 and DZ23C6V8, AZ23C6V8-7 uniquely delivers matched dual Zeners in a common-anode configuration - reducing component count by 50% versus dual singles and enabling symmetric reference generation unattainable with common-cathode alternatives.

FAQ
What is the maximum continuous Zener current for AZ23C6V8-7 at 25°C?
The device supports up to 44 mA continuous Zener current at 25°C ambient, calculated from its 300 mW power rating and nominal 6.8 V breakdown voltage (PD/VZ = 300 mW / 6.8 V ≈ 44 mA). Derating begins above 70°C per the published power derating curve.
Can AZ23C6V8-7 be used in place of a single Zener diode?
Yes - either cathode (Pin 2 or Pin 3) can be used independently with the common anode (Pin 1) grounded, delivering full 6.8 V regulation capability. The unused cathode remains electrically isolated and does not affect performance of the active channel.
Is the 5% ΔVZ specification guaranteed per unit or lot-level?
The ≤5% voltage matching between the two Zener elements is tested and guaranteed per individual unit at 5 mA test current, as confirmed in Diodes' DS18003 Rev. 18 datasheet Section "Features" and validated through AEC-Q101 stress testing protocols.
Does AZ23C6V8-7 support reflow soldering per J-STD-020?
Yes - the SOT23 package is rated for moisture sensitivity level 1 and qualified for standard Pb-free reflow profiles per J-STD-020, with peak temperatures up to 260°C. Recommended pad layout and thermal relief patterns are provided in Diodes' package outline documentation.
