Product details
Overview
AZ23C5V6W from Diodes Incorporated is a dual anode-cathode common-cathode Zener diode in SOT-323 package, rated for 5.6 V nominal Zener voltage at 5 mA test current, 200 mW power dissipation, and ±2.5 mV/°C temperature coefficient - used for precision voltage reference and transient suppression in low-power sensor signal conditioning circuits.
For engineers reviewing the AZ23C5V6W datasheet, AZ23C5V6W pinout, AZ23C5V6W application, or AZ23C5V6W equivalent, key selection criteria include Zener voltage tolerance (±5%), dynamic impedance (40 Ω at 5 mA), reverse leakage (1.0 μA at 4.2 V), ESD robustness (8 kV HBM), and AEC-Q101 qualification for automotive subsystems.
Technical Context
This dual-Zener device integrates two identical 5.6 V Zener elements sharing a common cathode terminal, enabling bidirectional clamping or dual-rail reference generation in compact space-constrained layouts. Its SOT-323 package supports high-density routing while maintaining thermal resistance of 625 °C/W on FR4 PCBs with recommended pad layout.
The device operates across –65 °C to +150 °C and exhibits stable breakdown behavior under pulsed conditions per JEDEC JESD22-A114, with specified Zener impedance measured at 1 kHz and derated power above 25 °C per Fig. 1's linear derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal at IZT = 5 mA; ±5% tolerance (5.32–5.88 V) ensures stable reference in 3.3 V/5 V rail monitoring |
| Power Dissipation | 200 mW at TA = 25 °C; derates linearly to zero at 150 °C - limits continuous clamp energy in ESD protection paths |
| Zener Impedance | 40 Ω at IZT = 5 mA and f = 1 kHz - defines voltage regulation stiffness under dynamic load transients |
| Reverse Leakage | 1.0 μA max at VR = 4.2 V - enables low-quiescent-current biasing in battery-powered sensor interfaces |
| Temp. Coefficient | –2.0 to +2.5 mV/°C - supports <±10 mV drift over –40 to +125 °C automotive ambient range |
| ESD Rating | HBM 8 kV, MM 400 V per AEC-Q101 - qualifies for direct placement on CAN/LIN bus nodes without external TVS |
| Package | SOT-323 (2.2 × 1.35 × 0.9 mm); moisture sensitivity level 1 - compatible with standard reflow profiles and automated assembly |
Pinout & Package
SOT-323 three-terminal surface-mount package with dual anode configuration: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). Molded plastic case meets UL 94V-0 flammability rating and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | First Zener junction anode; connects to protected node requiring negative-going transient clamping |
| Pin 2 | Cathode (common) | Shared cathode for both Zener junctions; ties to reference rail (e.g., 3.3 V or ground) |
| Pin 3 | Anode 2 | Second Zener junction anode; enables bidirectional clamping or dual-rail voltage reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener topology | Enables symmetrical ±5.6 V clamping or independent 5.6 V references from single footprint |
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements |
| Low leakage (1.0 μA) | Minimizes standby current draw in always-on sensor nodes and wake-up circuits |
| Green molding compound | Halogen-free, antimony-free construction compliant with Diodes Inc.'s environmental policy |
| Ultra-small SOT-323 | 0.006 g weight and 2.2 × 1.35 mm footprint reduce PCB area by >40% vs. SOT-23 equivalents |
Applications
| Automotive LIN Bus Transceiver Protection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protects LIN physical layer transceivers against ESD events and load dump-induced voltage spikes on 12 V supply lines. IC Role / Device Role / Timing Role: Bidirectional Zener clamp placed between LIN bus line and ground, leveraging dual-anode symmetry for ±5.6 V rail-to-rail clamping.

IC Role / Device Role / Timing Role: Precision 5.6 V reference source for ADC biasing and ratiometric measurement calibration. Use Value: Delivers <±10 mV total drift over –40 to +125 °C, enabling <0.1% full-scale error in 12-bit sensor readings. |
| USB-C Port ESD Clamp | Smart Meter Voltage Monitor |
Use Scenario: Suppresses contact ESD on USB-C CC and VCONN lines per IEC 61000-4-2 Level 4 (8 kV contact). IC Role / Device Role / Timing Role: Low-capacitance (<10 pF typical) Zener pair shunting transient energy to ground during plug insertion events. Use Value: Prevents latch-up in USB-C controller ICs without distorting high-speed signaling due to sub-10 pF junction capacitance. | Use Scenario: Monitors 230 V AC mains-derived DC rails in utility smart meters for brownout detection. IC Role / Device Role / Timing Role: Zener-based overvoltage/undervoltage comparator input stage with hysteresis set by resistor divider. Use Value: Achieves ±0.5% trip accuracy across 10-year field life using stable 5.6 V reference and <1 μA leakage to minimize divider power loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage reference and transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V6,115 | Single Zener, SOD-323, 5.6 V ±5%, 200 mW, 40 Ω ZZT, no AEC-Q101 | Lacks dual-anode topology; requires two devices for bidirectional clamping | Select when only unidirectional clamping is needed and automotive qualification is not required |
| MMBZ5226BS-7-F | Dual Zener, SOT-363, 5.6 V ±5%, 200 mW, 60 Ω ZZT, AEC-Q101 qualified | Larger 2.2 × 2.2 mm footprint; higher ZZT reduces regulation precision | Select when board space allows larger package and higher dynamic impedance is acceptable |
Compared with BZX384-B5V6 and MMBZ5226BS, AZ23C5V6W uniquely combines dual-anode functionality, AEC-Q101 qualification, and minimal 2.2 × 1.35 mm footprint - making it optimal for space-constrained automotive and industrial clamping where bidirectional symmetry and reliability are critical.

FAQ
What is the maximum peak pulse power this device can handle in ESD protection?
AZ23C5V6W is rated for 200 mW steady-state dissipation, but its short-duration pulse capability is defined by AEC-Q101 HBM testing at 8 kV - corresponding to ~0.2 J energy per event. It is not rated for IEC 61000-4-5 surge events; use dedicated TVS diodes for >1 A surge currents.
Can this dual-Zener be used as a 5.6 V voltage reference for ADCs?
Yes - its 5.6 V nominal Zener voltage, ±5% tolerance, and low 40 Ω dynamic impedance enable stable reference generation. For best accuracy, operate at IZ = 5 mA with thermal management, and account for –2.0 to +2.5 mV/°C temperature coefficient in system calibration.
Is the SOT-323 package compatible with standard reflow soldering profiles?
Yes - the SOT-323 package has moisture sensitivity level 1 per J-STD-020D and is qualified for lead-free reflow. Use Diodes Inc.'s recommended pad layout (AP02001.pdf) and follow peak temperatures ≤260 °C for ≤10 seconds to ensure solder joint integrity and avoid delamination.
Does the "W" suffix indicate automotive qualification?
Yes - the "W" in AZ23C5V6W denotes AEC-Q101 qualification per the Diodes Incorporated datasheet DS30257 Rev. 9. This includes stress testing for HBM ESD (8 kV), temperature cycling, and high-temperature operating life - confirming suitability for automotive powertrain and body electronics.
