Product details
Overview
AZ23C2V7-7-F from Diodes Incorporated is a dual common-anode 300 mW surface-mount Zener diode with nominal zener voltage 2.7 V (2.5–2.9 V range), ±5% matching between diodes, and 83 Ω dynamic impedance at 5 mA test current - used for precision voltage reference and overvoltage clamping in low-power analog sensor interfaces.
For engineers reviewing the AZ23C2V7-7-F datasheet, AZ23C2V7-7-F pinout, AZ23C2V7-7-F application, or AZ23C2V7-7-F equivalent, key selection criteria include matched dual-zener tolerance, SOT23 thermal resistance (417 °C/W), JEDEC-qualified reliability, AEC-Q101 ESD rating (HBM 8 kV), and automotive-grade availability via Q-suffix variants.
Technical Context
This dual Zener operates in reverse breakdown with two anodes tied internally and separate cathodes, enabling bidirectional clamping or dual-reference generation from a single package. Its temperature coefficient of –0.065 %/°C ensures stable regulation near room temperature.
The device is rated for continuous operation from –65 °C to +150 °C, with power derating beginning above 25 °C ambient per the defined curve. Thermal resistance (RθJA = 417 °C/W) assumes FR-4 PCB mounting with Diodes' recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.5–2.9 V at IZT = 5 mA - defines clamping threshold for low-voltage rail protection |
| Power Dissipation (PD) | 300 mW - sets maximum continuous DC or pulse energy handling on standard FR-4 board |
| Zener Impedance (ZZT) | 83 Ω at 5 mA - determines regulation stiffness and output ripple under load variation |
| Temperature Coefficient | –0.065 %/°C - indicates slight negative drift; enables predictable biasing in temp-stable references |
| ESD Rating (HBM) | 8 kV - qualifies for handling in non-ESD-controlled assembly environments without extra safeguards |
| Package | SOT23 - enables high-density placement and compatibility with automated pick-and-place systems |
Pinout & Package
Package: SOT23 - molded green plastic, UL 94V-0 rated, matte tin-plated alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Common anode connection for first Zener element; tied internally to Pin 3 |
| Pin 2 | Cathode 1 | Independent cathode for first Zener; used for unidirectional clamping or reference |
| Pin 3 | Anode 2 / Common Anode | Shared anode node for both Zeners; electrically identical to Pin 1 |
| Pin 4 | Cathode 2 | Independent cathode for second Zener; enables dual-rail referencing or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener, common anode | Enables compact dual-reference generation or symmetrical clamping without discrete pairing |
| ≤5% VZ matching | Ensures consistent voltage thresholds across both elements for balanced signal conditioning |

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 |
|---|---|---|---|
| BZX84C2V7LT1G | Single Zener, same VZ and SOT23 package; no dual-element or matching spec | Requires two devices for dual-rail use; lacks common-anode topology | Select when only one reference/clamp is needed and board space allows duplication |
| DZ23C2V7-7-F | Common-cathode dual Zener variant; identical VZ, matching, and power rating | Better suited for ground-referenced clamping where cathodes tie to common return | Choose for designs requiring cathode-common architecture instead of anode-common |
Compared with BZX84C2V7LT1G and DZ23C2V7-7-F, AZ23C2V7-7-F uniquely supports anode-common bidirectional clamping in a single footprint, reducing component count and improving matching-critical reference stability without altering PCB layout.

FAQ
What is the maximum reverse current (IR) specification for AZ23C2V7-7-F?
The datasheet specifies a maximum reverse current of 0.1 µA at VR = 1.0 V, measured at 25 °C. This low leakage supports accurate voltage monitoring in battery-powered systems where standby current must remain below 1 µA. No higher IR values are guaranteed across temperature or voltage ranges.
Can AZ23C2V7-7-F be used in place of a single Zener diode?
Yes - either cathode (Pin 2 or Pin 4) can be used independently with the common anode (Pins 1 & 3) to function as a standard 2.7 V Zener. The unused cathode remains electrically isolated and does not affect performance, making it backward-compatible in legacy single-Zener layouts.
Is there a qualified automotive version of AZ23C2V7-7-F?
Yes - the automotive-grade variant is AZ23C2V7Q-7-F, qualified to AEC-Q101, manufactured in IATF 16949-certified facilities, and PPAP-capable. It shares identical electrical specs and SOT23 packaging but adds change control documentation and extended reliability testing for automotive applications.
How does the –0.065 %/°C temperature coefficient impact circuit design?
This negative coefficient means VZ decreases by ~1.75 mV/°C near 25 °C. In precision references, it requires compensation in wide-temperature-range designs - e.g., pairing with a positive-TC component or using trimming resistors. For clamping, it results in tighter voltage margins at elevated temperatures, improving surge margin in hot environments.
