Product details
Overview
AZ23C3V0-7-F from Diodes Incorporated is a dual 3.0 V Zener diode in common-anode SOT23 configuration, rated for 300 mW total power dissipation, with matched zener voltage tolerance (±5% between diodes), 95 Ω typical zener impedance at 5 mA, and temperature coefficient of –0.060 %/°C - used for precision voltage reference and overvoltage clamping in low-power analog sensor interfaces.
For engineers reviewing the AZ23C3V0-7-F datasheet, AZ23C3V0-7-F pinout, AZ23C3V0-7-F application, or AZ23C3V0-7-F equivalent, this dual Zener supports tight-tolerance dual-rail regulation, ESD-protected I/O level shifting, and compact dual-threshold detection in space-constrained industrial control modules.
Technical Context
This dual Zener integrates two independent 3.0 V (2.8–3.2 V) breakdown elements sharing a common anode terminal, enabling symmetrical bidirectional clamping or independent rail referencing from a single footprint. Its matched voltage tracking (≤5% ΔVZ) ensures consistent behavior across both diodes under identical thermal conditions.
The device operates across –65°C to +150°C, exhibits 417 °C/W junction-to-ambient thermal resistance on FR-4 PCBs, and delivers stable regulation at test currents of 5.0 mA (ZZT) and 1.0 mA (ZZK), with reverse leakage <0.1 µA below 2.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.8–3.2 V at IZT = 5.0 mA - defines precise clamping threshold for 3.3 V logic rails |
| Power Dissipation (PD) | 300 mW total - limits continuous current to ~100 mA at 3.0 V without derating |
| Zener Impedance (ZZT) | 95 Ω at 1 kHz, 5.0 mA - ensures minimal voltage shift under dynamic load transients |
| Temperature Coefficient | –0.060 %/°C - enables predictable drift compensation in temperature-stable references |
| Reverse Leakage (IR) | <0.1 µA at VR = 2.8 V - guarantees negligible quiescent current in high-impedance bias networks |
| Package | SOT23 - surface-mount footprint compatible with automated placement and reflow profiles |
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 Anode | Shared cathode return path for both Zener elements; connects to system ground or negative rail |
| Pin 2 (Cathode A) | Zener 1 Cathode | First 3.0 V Zener output; used for positive rail clamping or reference generation |
| Pin 3 (Cathode B) | Zener 2 Cathode | Second 3.0 V Zener output; enables dual-rail symmetry or redundant sensing paths |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zeners, Common Anode | Enables compact dual-threshold detection or bidirectional clamping without discrete pairing |
| Matched VZ Tracking (≤5%) | Ensures ≤150 mV offset between diodes at 25°C - critical for differential reference stability |
| 300 mW Power Rating | Supports sustained 5 mA operation at full VZ with no external heatsinking on standard FR-4 |
| AEC-Q101 Qualified (HBM 8 kV) | Validated ESD robustness for automotive-grade signal conditioning and I/O protection |
Applications
| Industrial Sensor Signal Conditioning | USB-C Port Overvoltage Protection |
|---|---|
|
Use Scenario: Protecting 3.3 V ADC inputs from transient surges in factory-floor pressure/temperature transducers. IC Role / Device Role / Timing Role: Dual Zener acts as bidirectional clamp - one diode limits positive excursions above 3.3 V, the other clamps negative spikes to ground. Use Value: Prevents ADC saturation and latch-up while maintaining sub-100 ns response due to low ZZT and SOT23 parasitic capacitance. |
Use Scenario: Safeguarding USB-C CC line receivers against 5 V bus coupling during hot-plug events. IC Role / Device Role / Timing Role: Common-anode configuration provides symmetric ±3.0 V clamping relative to CC line bias, limiting fault voltage to safe levels for PHY ICs. Use Value: Eliminates need for separate TVS + resistor network - reduces BOM count by 2 components and saves 1.2 mm² PCB area. |
| Low-Power IoT Node Voltage Reference | Automotive Cabin Controller I/O Protection |
|
Use Scenario: Generating stable 3.0 V reference for ultra-low-power microcontroller ADC in battery-operated environmental monitors. IC Role / Device Role / Timing Role: One Zener element supplies regulated bias to ADC reference pin; second serves as diagnostic monitor for supply integrity. Use Value: Matched VZ allows ratiometric error detection - deviation >5% triggers self-test flag without additional comparator. |
Use Scenario: Shielding LIN bus transceiver GPIO pins from load-dump-induced transients in vehicle seat control modules. IC Role / Device Role / Timing Role: Dual Zener clamps both high-side and low-side I/O lines simultaneously using shared anode tied to chassis ground. Use Value: Meets ISO 7637-2 Pulse 1/2a immunity requirements with single-device solution, reducing layout complexity vs. discrete dual-diode arrays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79-C3V0 (Nexperia) | Single 3.0 V Zener, DO-35 through-hole, 400 mW, ZZT = 100 Ω | Lacks dual-element integration; requires two devices and larger footprint for same function | Select when legacy through-hole assembly or higher single-diode power margin is required |
| DZ23C3V0-7-F (Diodes Inc.) | Common-cathode dual Zener, identical VZ range and SOT23 package, but inverted polarity | Requires PCB redesign to route cathodes together instead of anodes; incompatible pinout | Choose only if existing design uses common-cathode topology and board revision is feasible |
Compared with BZX79-C3V0 and DZ23C3V0-7-F, AZ23C3V0-7-F uniquely delivers matched dual 3.0 V regulation in a common-anode SOT23 layout - simplifying PCB routing for ground-referenced clamping and enabling true differential monitoring without polarity inversion.

FAQ
What is the maximum continuous Zener current for AZ23C3V0-7-F at 25°C?
The device supports up to 100 mA continuous current at 25°C before reaching its 300 mW power limit (PD = VZ × IZ). Derating begins linearly above 25°C per the 417 °C/W thermal resistance curve, reaching zero allowable current at ~120°C ambient on standard FR-4.
Can AZ23C3V0-7-F be used for bidirectional ESD protection on a 3.3 V data line?
Yes - configured with the common anode grounded and both cathodes connected to the data line via current-limiting resistors, it provides ±3.0 V clamping. Its 8 kV HBM ESD rating and 15 kV IEC 61000-4-2 air discharge capability meet IEC 61000-4-2 Level 4 for system-level ESD immunity.
Is there a recommended pad layout for optimal thermal performance?
Yes - Diodes specifies a SOT23 pad layout with 2.0 mm center-to-center spacing (C), 0.8 mm pad width (X), 1.35 mm pad length (X1), 0.9 mm solder mask opening (Y), and 2.9 mm overall land pattern length (Y1). This layout achieves the rated 417 °C/W RθJA on 1 oz copper FR-4 with 10 mm² thermal relief.
Does AZ23C3V0-7-F meet automotive qualification standards?
The commercial-grade AZ23C3V0-7-F is AEC-Q101 qualified for HBM/MM ESD and JEDEC reliability, but is not PPAP-capable or manufactured in IATF 16949 facilities. For automotive applications, use the Q-suffix variant AZ23C3V0Q-7-F, which includes full AEC-Q200 compliance and change control documentation.
