Product details
Overview
AZ23C6V8W-7-F from Diodes Incorporated is a dual anode-cathode common-cathode 6.8V Zener diode in SOT-323 package, rated for 200mW power dissipation, 15Ω zener impedance at 5mA, and ±4.0mV/°C temperature coefficient - used for precision voltage reference and transient suppression in low-power sensor interfaces.
For engineers reviewing the AZ23C6V8W-7-F datasheet, AZ23C6V8W-7-F pinout, AZ23C6V8W-7-F application, or AZ23C6V8W-7-F equivalent, key selection criteria include nominal Zener voltage (6.8V), max reverse current (2.0μA @ 5.5V), thermal resistance (625°C/W), ESD robustness (IEC 61000-4-2 air >25kV), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-Zener device integrates two independent 6.8V Zener junctions sharing a common cathode terminal, enabling bidirectional clamping or dual-rail reference generation. Its SOT-323 package supports high-density PCB layouts while maintaining thermal performance up to 150°C junction temperature.
The device operates with tight voltage tolerance (6.47–7.14V at 5mA), low dynamic impedance (15Ω), and stable temperature coefficient (+1.2 to +4.5mV/°C), making it suitable for voltage regulation in battery-powered instrumentation where supply headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage @ 5mA | 6.8V (nominal); min 6.47V / max 7.14V - defines regulated output range under standard test conditions |
| Max Zener Impedance | 15Ω at 5mA - ensures minimal voltage deviation during load transients |
| Power Dissipation | 200mW - limits continuous DC power handling on FR4 board with recommended pad layout |
| Thermal Resistance | 625°C/W - determines junction-to-ambient temperature rise per watt dissipated |
| Temp Coefficient | +1.2 to +4.5mV/°C - quantifies voltage drift over operating temperature range (-65°C to +150°C) |
| Reverse Current | 2.0μA @ 5.5V - specifies leakage level below breakdown, critical for low-power standby circuits |
| ESD Rating | HBM 8kV, IEC 61000-4-2 air >25kV - validates robustness against electrostatic discharge in assembly and field use |
Pinout & Package

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-C6V8LT1G | Single Zener (not dual), same 6.8V nominal, 15Ω Zzt, but no common-cathode dual configuration | Requires two devices for dual-rail clamping; lacks integrated dual-anode topology | Select when only single-rail reference needed and board space allows discrete placement |
| MMBZ5235BLT1G | Single Zener, 6.8V, 10Ω Zzt, higher 225mW rating, but not AEC-Q101 qualified | Higher power margin but unqualified for automotive; lower impedance improves regulation accuracy | Prefer for industrial non-automotive applications requiring tighter voltage stability |
Compared with BZX84-C6V8LT1G and MMBZ5235BLT1G, AZ23C6V8W-7-F uniquely delivers dual 6.8V Zeners in one SOT-323 package with AEC-Q101 and IEC 61000-4-2 certification - essential for space-constrained, safety-critical automotive and industrial designs requiring bidirectional clamping.

FAQ
What is the maximum reverse voltage before breakdown for AZ23C6V8W-7-F?
The nominal Zener voltage is 6.8V at 5mA test current, with guaranteed range of 6.47V to 7.14V. Breakdown occurs within this band; operation below 5.5V yields ≤2.0μA reverse leakage, confirming sub-threshold blocking behavior.
Can AZ23C6V8W-7-F be used for bidirectional ESD protection?
Yes - its dual-anode/common-cathode structure allows connection as a back-to-back Zener pair across signal lines, providing ±6.8V clamping with matched voltage thresholds and certified IEC 61000-4-2 air discharge >25kV performance.
Is thermal derating required above 25°C ambient?
Yes - power dissipation must be linearly derated above 25°C using RθJA = 625°C/W. At 85°C ambient, maximum allowable power drops to 100mW, calculated as PD = 200mW × (1 − (85−25)/625).
Does AZ23C6V8W-7-F meet automotive qualification standards?
Yes - it is fully qualified to AEC-Q101 (HBM 8kV, MM 400V) and manufactured with green, halogen-free molding compound compliant with automotive environmental requirements and UL 94V-0 flammability rating.
