Product details
Overview
AZ23C36-7-F from Diodes Incorporated is a dual common-anode 36V Zener diode pair in SOT23 package, rated for 300mW total power dissipation, with ±5% matching between zener voltages (34–38V at 5mA), 90Ω typical zener impedance, and +0.09%/°C temperature coefficient - used for precision voltage reference and overvoltage clamping in DC power rail monitoring circuits.
For engineers reviewing the AZ23C36-7-F datasheet, AZ23C36-7-F pinout, AZ23C36-7-F application, or AZ23C36-7-F equivalent, key selection criteria include matched dual-zener tolerance, thermal resistance (417°C/W), JEDEC-qualified reliability, AEC-Q101 HBM ESD rating (8kV), and SOT23 footprint compatibility with automated assembly.
Technical Context
This dual Zener operates in common-anode configuration: both cathodes are independent terminals, sharing one anode connection. It delivers stable 34–38V regulation at IZT = 5mA with <5% inter-diode VZ mismatch under same thermal conditions.
Thermal derating begins above 25°C ambient, with full 300mW dissipation only at TA ≤ 25°C; junction-to-ambient thermal resistance is 417°C/W on FR-4 board with recommended pad layout. Operating temperature range spans –65°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage Range | 34–38 V at 5 mA - defines usable regulation band for overvoltage protection or reference generation |
| Power Dissipation | 300 mW - maximum total device power before thermal shutdown or degradation in standard SOT23 mounting |
| Zener Impedance | 90 Ω at 5 mA - indicates regulation stiffness; lower values improve load regulation performance |
| Temperature Coefficient | +0.09 %/°C - positive drift enables predictable compensation in temperature-sensitive references |
| Reverse Leakage | ≤0.1 µA at 27 V - ensures minimal quiescent current in high-impedance bias networks |
| ESD Rating | HBM 8 kV, IEC 61000-4-2 Contact 8 kV - supports robust handling in manufacturing and field environments |
Pinout & Package
Package: SOT23 - surface-mount plastic package with matte tin-plated alloy-42 leadframe, UL 94V-0 rated, moisture sensitivity level 1 per J-STD-020.

| Cathode A (Pin 2) | Zener A Cathode | First regulated output node; reverse-biased to generate 34–38 V reference |
| Cathode B (Pin 3) | Zener B Cathode | Second independent regulated output; enables dual-rail sensing or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener Matching | ΔVZ ≤ 5% between diodes - enables accurate differential or ratiometric voltage monitoring |

Applications
| Industrial Power Supply Monitoring | Automotive Body Control Module (BCM) Voltage Clamp |
|---|---|
Use Scenario: Real-time detection of 36V rail overvoltage in programmable logic controller (PLC) backplane supplies. IC Role / Device Role / Timing Role: Dual-Zener clamps protect downstream ADC inputs and microcontroller I/O pins from transient excursions beyond 38V. Use Value: Matched VZ ensures consistent trip threshold across dual-sensing paths, reducing false alarms in safety-critical monitoring. |
Use Scenario: Clamping battery-supplied 36V subsystems (e.g., HVAC actuators) during load-dump events in 24V commercial vehicles. IC Role / Device Role / Timing Role: Provides fast-response overvoltage suppression without external drivers or timing components. Use Value: AEC-Q101 qualification and 150°C max operating temperature ensure functional integrity under under-hood thermal stress. |
| Test Equipment Reference Calibration | Telecom Line Interface Protection |
Use Scenario: Stable dual-reference source for calibrating 36V-range bench multimeters and data acquisition modules. IC Role / Device Role / Timing Role: Supplies matched, temperature-compensated reference nodes for ratiometric DAC/ADC calibration routines. Use Value: +0.09%/°C TC allows predictable correction algorithms; low leakage (<0.1µA) preserves high-impedance reference integrity. |
Use Scenario: Overvoltage protection on 36V auxiliary power lines feeding remote radio units in 4G/5G base stations. IC Role / Device Role / Timing Role: Absorbs induced surges while maintaining low capacitance (<2 pF at 1V) to avoid signal distortion. Use Value: 90Ω zener impedance minimizes regulation error during surge conduction; SOT23 footprint saves PCB space in dense RF layouts. |
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 |
|---|---|---|---|
| BZX84-C36LT1G | Single 36V Zener in SOT23; no dual-element matching or common-anode topology | Lacks inter-diode VZ matching; suitable only for single-rail clamping | Select when dual-channel correlation is unnecessary and cost-per-channel is prioritized |
| DZ23C36-7-F | Same dual-common-cathode configuration; identical VZ range but inverted polarity architecture | Requires PCB layout revision to accommodate cathode-common vs. anode-common routing | Choose if existing design uses common-cathode topology or requires backward compatibility with DZ23 series footprints |
Compared with BZX84-C36LT1G and DZ23C36-7-F, AZ23C36-7-F uniquely provides matched dual-anode-referenced clamping in a single SOT23, enabling compact dual-rail supervision without external matching components or polarity inversion.

FAQ
What is the maximum continuous power dissipation for AZ23C36-7-F?
The AZ23C36-7-F has a maximum power dissipation of 300 mW at TA = 25°C on a standard FR-4 PCB with Diodes' recommended pad layout. Derating is linear above 25°C at 0.72 mW/°C, reaching zero dissipation at approximately 445°C ambient - though practical operation is limited to –65°C to +150°C junction temperature.
How is the "DS" marking code related to AZ23C36-7-F?
"DS" is the official Diodes Incorporated marking code printed on the top of the SOT23 package for AZ23C36-7-F devices. It uniquely identifies the 34–38V Zener voltage grade within the AZ23C2V7–AZ23C51 family and is used for traceability and visual verification during assembly and inspection.
Can AZ23C36-7-F be used in automotive applications?
Yes - AZ23C36-7-F is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. For PPAP-capable automotive programs, the automotive-grade variant AZ23C36Q-7-F (with Q-suffix) is available and fully compatible in form, fit, and function.
What is the typical zener impedance at low test current?
At IZK = 1.0 mA, the typical zener impedance (ZZK) is 250 Ω. This value reflects higher dynamic resistance near knee voltage and informs design margins when operating below nominal 5 mA test current - critical for low-power bias networks where regulation stability must be verified across the full operating current range.
