Product details
Overview
AZ23C6V8-7-F 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 packages for power supply regulation and signal conditioning circuits.
For engineers reviewing the AZ23C6V8-7-F datasheet, AZ23C6V8-7-F pinout, AZ23C6V8-7-F application, or AZ23C6V8-7-F equivalent, key selection criteria include dual-Zener matching (≤5% ΔVZ), low thermal resistance (417 °C/W), JEDEC-qualified reliability, AEC-Q101 HBM ESD rating (8 kV), and RoHS-compliant green packaging.
Technical Context
This dual Zener operates in common-anode configuration, enabling bidirectional voltage clamping or dual-reference generation from a single package. Each Zener junction is individually characterized: VZ = 6.4–7.2 V at IZT = 5.0 mA, ZZT = 8.0 Ω, and TC = +0.045 %/°C - indicating stable regulation across temperature.
Thermal performance is defined for FR-4 PCB mounting per recommended pad layout (2.0 mm × 0.9 mm pads), with maximum power dissipation derated linearly above 25 °C ambient per Fig. 1. The device meets IEC 61000-4-2 ESD immunity (8 kV contact, 15 kV air) and is qualified to AEC-Q101 for automotive-grade reliability.

|---|---|---|---|
| BZX79-C6V8 (Nexperia) | Single Zener, DO-35 through-hole, 500 mW, VZ = 6.4–7.2 V, ZZT = 10 Ω | Lacks dual-junction capability and SMT compatibility - unsuitable for space-constrained or automated assembly | Select only if through-hole mounting and higher power margin are prioritized over footprint and matching. |
| DZ23C6V8-7-F (Diodes Inc.) | Common-cathode dual Zener, same VZ range and SOT23 package, but inverted polarity configuration | Requires circuit redesign to accommodate cathode-common topology - not drop-in compatible | Choose when common-cathode architecture aligns with existing board layout or bias network design. |
Compared with BZX79-C6V8 and DZ23C6V8-7-F, AZ23C6V8-7-F uniquely delivers matched dual Zeners in common-anode SOT23 form - enabling compact, symmetric clamping without layout revision or power derating.

FAQ
What is the maximum continuous Zener current for AZ23C6V8-7-F at 25°C ambient?
The maximum continuous Zener current is derived from PD = 300 mW and VZ ≈ 6.8 V, yielding IZ(max) ≈ 44 mA. However, the datasheet specifies test current IZT = 5.0 mA for parameter characterization, and operation above 20 mA requires thermal derating per Fig. 1 due to RθJA = 417 °C/W.
Is AZ23C6V8-7-F suitable for bidirectional ESD protection?
No - AZ23C6V8-7-F is a dual common-anode Zener, not a dedicated TVS diode. While it can clamp moderate transients, its 8.0 Ω ZZT and 300 mW rating limit peak pulse handling. For IEC 61000-4-2 ESD protection, use purpose-built TVS arrays like Diodes' D3V3Z1BQ-7.
How does the common-anode configuration affect circuit implementation?
In common-anode configuration, both Zener cathodes (Pins 2 and 3) are independently accessible while the shared anode (Pin 1) connects to ground or a negative rail. This allows either unidirectional clamping (one cathode to signal, anode to ground) or differential reference generation (cathodes to separate nodes, anode to common point).
Does AZ23C6V8-7-F require derating at elevated ambient temperatures?
Yes - per Fig. 1, power dissipation must be linearly derated above 25°C ambient at 0.72 mW/°C (300 mW ÷ 417 °C/W). At 85°C ambient, maximum allowable power drops to ~172 mW, limiting usable Zener current to ~25 mA for VZ = 6.8 V.
