Product details
Overview
AZ23C10-7-F from Diodes Incorporated is a dual common-anode 300 mW surface-mount Zener diode with nominal Zener voltage 10 V (9.4–10.6 V range), ±5% matching between diodes, and 15 Ω typical Zener impedance at 5 mA. It operates from −65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the AZ23C10-7-F datasheet, AZ23C10-7-F pinout, AZ23C10-7-F application, or AZ23C10-7-F equivalent, this part supports dual-rail clamping, low-drift reference generation, and space-constrained dual-Zener designs requiring matched breakdown characteristics and JEDEC-qualified reliability.
Technical Context
This dual Zener integrates two identical Zener elements sharing a common anode terminal in a single SOT23 package, enabling compact dual-voltage regulation or bidirectional clamping without discrete pairing. Its thermal resistance (RθJA) is 417 °C/W on FR-4 PCB with recommended pad layout.
The device exhibits +0.065 %/°C temperature coefficient and maintains ≤5% ΔVZ between diodes under same test conditions. Reverse leakage remains ≤0.1 µA at 7.5 V, supporting low-power biasing and sensing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 9.4–10.6 V at IZT = 5 mA - defines stable regulation window for 10 V reference designs |
| Power Dissipation | 300 mW - limits continuous Zener current to ~30 mA at 10 V, constraining thermal design |
| Zener Impedance | 15 Ω typical at 5 mA - ensures <150 mV output variation for ±1 mA load changes |
| Temperature Coefficient | +0.065 %/°C - predicts +6.5 mV/°C drift, critical for temperature-stable references |
| Max ΔVZ | ≤5% between diodes - enables matched dual-rail clamping without calibration |
| Operating Temp | −65 °C to +150 °C - supports automotive under-hood and industrial control environments |
| ESD Rating | HBM 8 kV, IEC 61000-4-2 Air 15 kV - withstands handling and system-level ESD events |
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 |
|---|---|---|---|
| BZX79-C10 (Nexperia) | Single Zener, DO-35 through-hole, 10 V ±5%, 400 mW, no matching spec | Requires two devices and board space for dual function; lacks ΔVZ guarantee | Choose only if through-hole assembly is mandatory and dual-element matching is unnecessary |
| DZ23C10-7-F (Diodes Inc.) | Common-cathode dual Zener, same SOT23 package, identical VZ range but inverted polarity | Requires PCB layout revision to route cathodes together instead of anodes | Select when existing design uses common-cathode topology or needs complementary clamping direction |
Compared with BZX79-C10 and DZ23C10-7-F, AZ23C10-7-F uniquely delivers matched dual-Zener performance in a surface-mount common-anode configuration-reducing component count, improving thermal coupling, and simplifying layout for high-reliability 10 V reference and clamping functions.

FAQ
What is the maximum continuous Zener current for AZ23C10-7-F at 25°C ambient?
At 25°C ambient and with recommended FR-4 pad layout, the maximum continuous Zener current is approximately 30 mA, derived from PD = 300 mW and VZ ≈ 10 V. Derating is required above 25°C per the power derating curve (Fig. 1), reaching zero dissipation at ~120°C ambient.
Can AZ23C10-7-F be used for bidirectional TVS-like clamping?
No-it is not rated or characterized as a transient voltage suppressor. While its dual common-anode structure allows clamping in one direction (cathodes to signal, anode to ground), it lacks specified peak pulse power, clamping voltage at high current, or waveform response. Use dedicated TVS arrays like DZ23 series for surge protection.
Is the 5% ΔVZ specification guaranteed across temperature?
No-the ≤5% matching is specified at TA = +25°C and IZT = 5 mA per the datasheet. Temperature-induced drift may cause divergence; actual mismatch at extremes depends on individual unit TC tracking, which is not characterized or guaranteed.
Does AZ23C10-7-F support reflow soldering per J-STD-020?
Yes-its moisture sensitivity level is rated Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and requires no baking prior to standard Pb-free reflow (peak 260°C). The matte tin finish ensures compatibility with SAC305 and SnPb pastes.
