Product details
Overview
AZ23C5V1-7 from Diodes Incorporated is a dual common-anode Zener diode in SOT23 package, rated for 300 mW total power dissipation, with nominal Zener voltage 5.1 V (4.8–5.4 V range), ±5% matching between diodes, and +0.005 %/°C temperature coefficient. It serves as precision voltage reference and overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the AZ23C5V1-7 datasheet, AZ23C5V1-7 pinout, AZ23C5V1-7 application, or AZ23C5V1-7 equivalent, key selection criteria include matched dual-Zener tolerance, thermal stability in compact layouts, SOT23 reflow compatibility, and compliance with JEDEC high-reliability standards for industrial control and sensor interface designs.
Technical Context
This device integrates two Zener diodes sharing a single anode terminal, enabling bidirectional clamping or dual-reference generation from one footprint. Its 60 Ω typical Zener impedance at 5 mA and 480 Ω at 1 mA support stable regulation under varying load conditions.
The +0.005 %/°C temperature coefficient ensures minimal drift across –65 °C to +150 °C operating range, while the 0.8 V minimum reverse voltage rating confirms reliable turn-on behavior below Zener threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 4.8–5.4 V @ IZT = 5 mA - defines usable reference/clamp window with ±5% unit-to-unit matching |
| Power Dissipation | 300 mW - maximum total device power handling on FR-4 board with recommended pad layout |
| Zener Impedance | 60 Ω @ 5 mA / 480 Ω @ 1 mA - determines output impedance and regulation stiffness under light/heavy loads |
| Temperature Coefficient | +0.005 %/°C - enables <10 mV drift over 100 °C ambient swing for stable biasing |
| Reverse Voltage | 0.8 V @ IR = 0.1 µA - confirms low leakage and sharp knee onset before breakdown |
| Package | SOT23 - surface-mount, JEDEC-compliant footprint supporting automated placement and reflow |
Pinout & Package
Package: SOT23 - molded plastic, green compound (UL 94V-0), matte tin-plated alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (common) | Shared cathode connection point for both Zener diodes; must be tied to lowest potential node in clamp/reference configuration |
| Pin 2 | Cathode 1 | First Zener cathode; reverse-biased to generate 5.1 V reference relative to common anode |
| Pin 3 | Cathode 2 | Second Zener cathode; identical electrical characteristics to Pin 2, enabling matched dual-channel operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zeners, common anode | Enables symmetrical bidirectional clamping or independent dual-reference generation without discrete pairing |
| ≤5% ΔVZ matching | Guarantees ≤270 mV absolute voltage difference between diodes at 5 mA, critical for differential sensing |
| JEDEC-qualified reliability | Meets AEC-Q101 HBM ESD (8 kV), IEC 61000-4-2 (15 kV air/8 kV contact), and high-temp storage (150 °C) |
| Lead-free & green compliant | Fully RoHS 3 (2015/863/EU), halogen-free (<900 ppm Br/Cl, <1000 ppm Sb), UL 94V-0 flammability rating |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79-C5V1 (Nexperia) | Single Zener, DO-35 through-hole, 500 mW, ±5% tolerance, no inter-device matching | Lacks dual-element integration; requires two devices and larger board area for matched function | Select when through-hole assembly is required and dual matching is not critical |
| DZ23C5V1 (Diodes Inc.) | Common-cathode dual Zener, same SOT23 package, identical VZ range and power rating | Inverts polarity logic: cathodes shared instead of anodes; requires circuit topology adjustment | Choose when existing design uses common-cathode topology or needs inverted clamping configuration |
Compared with BZX79-C5V1 and DZ23C5V1, AZ23C5V1-7 uniquely delivers matched dual-Zener performance in a compact common-anode SOT23 package, enabling space-efficient bidirectional clamping and differential reference generation without external matching components or layout compromises.

FAQ
What is the maximum continuous power dissipation for AZ23C5V1-7?
The AZ23C5V1-7 has a maximum power dissipation of 300 mW when mounted on an FR-4 PCB with Diodes Incorporated's recommended pad layout. Derating begins above 25 °C ambient, reaching zero dissipation at approximately 150 °C per the published derating curve.
How is the common-anode configuration used in circuit design?
In common-anode configuration, Pin 1 (anode) connects to the lowest system potential (e.g., ground or negative rail), while Pins 2 and 3 (cathodes) serve as independent Zener outputs. This enables bidirectional clamping-e.g., clamping a signal between –5.1 V and +5.1 V relative to ground-or dual positive references.
Does AZ23C5V1-7 meet automotive qualification standards?
The commercial-grade AZ23C5V1-7 is qualified to JEDEC high-reliability standards and AEC-Q101 for ESD, but it is not automotive-qualified by default. For automotive use, the Q-suffix variant AZ23C5V1Q-7-F must be selected-it undergoes full AEC-Q200 stress testing and is manufactured in IATF 16949-certified facilities.
Can AZ23C5V1-7 replace single-Zener diodes in existing designs?
Yes, but only if the circuit topology accommodates common-anode operation and dual-element integration. Replacing two discrete Zeners requires verifying that shared anode connection does not conflict with biasing schemes, and that the 300 mW total power limit applies to combined dissipation-not per diode.
