Product details

Overview

AZ23C3V6-7 from Diodes Incorporated is a dual common-anode 300 mW surface-mount Zener diode with nominal Zener voltage 3.6 V (3.4–3.8 V range), 95 Ω maximum Zener impedance at 5 mA, and −0.055 %/°C temperature coefficient - used for precision voltage reference and overvoltage clamping in low-power sensor signal conditioning circuits.

For engineers reviewing the AZ23C3V6-7 datasheet, AZ23C3V6-7 pinout, AZ23C3V6-7 application, or AZ23C3V6-7 equivalent, key selection criteria include dual-Zener matching (≤5% ΔV_Z), SOT23 package thermal resistance (417 °C/W), JEDEC-qualified reliability, and automotive-grade availability via Q-suffix variants.

Technical Context

This dual Zener operates in reverse breakdown mode with two independent anodes sharing a common cathode terminal, enabling bidirectional voltage regulation or symmetrical clamping in single-supply systems. Its matched pair ensures consistent reference tracking across temperature and bias conditions.

The device is rated for −65 °C to +150 °C operation, dissipates up to 300 mW on FR-4 PCB with recommended pad layout, and exhibits low capacitance (<100 pF) suitable for signal-line protection without bandwidth degradation.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage	3.4–3.8 V at I_ZT = 5 mA - defines stable regulation window for 3.3 V rail monitoring
Power Dissipation	300 mW - supports continuous clamping in low-duty-cycle transient suppression
Zener Impedance	95 Ω max at 5 mA - limits regulation error under load variation in reference circuits
Temperature Coefficient	−0.055 %/°C - enables predictable drift compensation in temperature-sensitive analog stages
Thermal Resistance	417 °C/W - requires minimal copper area for thermal management on standard PCBs
ESD Rating	HBM 8 kV / IEC 61000-4-2 Air 15 kV - qualifies for direct interface with exposed I/O lines

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin-plated alloy 42 leadframe, UL 94V-0 rated, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode of Zener 1	First regulated node; connects to protected signal line or reference input
Pin 2	Cathode (common)	Shared breakdown node; ties to system ground or bias rail for dual-clamp configuration
Pin 3	Anode of Zener 2	Second regulated node; enables symmetrical ±V_Z clamping or dual-reference generation

Key Features

Feature	Design Value
Dual Zeners, common cathode	Enables bidirectional clamping or matched reference pairs without external routing
ΔV_Z ≤ 5%	Ensures <±0.18 V tracking between diodes - critical for differential sensing and ratiometric designs
JEDEC-qualified reliability	Validated per AEC-Q101 for high-reliability industrial and automotive applications
Halogen- and antimony-free	Complies with RoHS 3 and "Green" definitions (<900 ppm Br/Cl, <1000 ppm Sb)

Applications

Industrial Sensor Signal Conditioning

USB-C Port Overvoltage Protection

Use Scenario: Protecting 3.3 V ADC inputs from ESD and supply rail transients in factory-floor pressure sensors.

IC Role / Device Role / Timing Role: Dual-Zener clamp limiting input swing to ±3.6 V relative to ground, preserving ADC full-scale range.

Use Value: Prevents latch-up and input-stage damage while maintaining <0.5% reference accuracy over −40 °C to +85 °C.

Use Scenario: Clamping CC1/CC2 configuration channel pins against hot-swap surges in USB-C receptacles.

IC Role / Device Role / Timing Role: Common-cathode dual Zener shunting both CC lines to GND during plug insertion events.

Use Value: Achieves <10 ns response with <100 pF capacitance - avoids signal integrity loss in 300 kHz BMC communication.

Automotive Cabin Controller Reference

IoT Node Battery Voltage Monitor

Use Scenario: Providing stable 3.6 V reference for microcontroller brown-out detection in HVAC control modules.

IC Role / Device Role / Timing Role: Zener 1 supplies regulated reference; Zener 2 monitors backup battery voltage threshold.

Use Value: Matches temperature drift across both diodes (−0.055 %/°C), eliminating calibration drift in wide-temp environments.

Use Scenario: Monitoring Li-ion cell voltage in BLE-enabled asset trackers using MCU ADC with internal reference.

IC Role / Device Role / Timing Role: Zener 1 regulates reference; Zener 2 clamps ADC input during charge termination spikes.

Use Value: Delivers <1.5% total error across 2.5–4.2 V battery range with no external op-amp buffering required.

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-C3V6-7-F	Single Zener, same V_Z and SOT23 package; lacks dual-element matching	Cannot support matched dual-clamp or differential reference topologies	Select when only one regulated node is needed and board space permits discrete placement
DZ23C3V6-7-F	Common-anode dual Zener, identical electrical specs but different marking and qualification path	Same circuit function; DZ23 series uses alternate date-code and traceability scheme	Preferred for legacy BOM continuity where DZ23 prefix is already qualified

Compared with BZX84-C3V6-7-F and DZ23C3V6-7-F, AZ23C3V6-7 uniquely delivers guaranteed ≤5% inter-diode V_Z matching in a JEDEC-qualified SOT23, making it essential for precision dual-reference or symmetrical clamping where tracking matters.

FAQ

What is the maximum reverse current before breakdown for AZ23C3V6-7?

The datasheet specifies a minimum reverse voltage (V_R) of - V (not applicable for this part number), indicating no guaranteed reverse blocking threshold below Zener onset. At I_ZK = 1.0 mA, the knee voltage is typically near 3.0 V, and stable regulation begins above 3.4 V. Designers should use the 5 mA test point for specification compliance.

Can AZ23C3V6-7 be used in place of a single Zener diode?

Yes - either anode (Pin 1 or Pin 3) can be used independently with the common cathode (Pin 2) as a standard Zener, delivering 3.4–3.8 V regulation at 5 mA. However, the second anode remains unconnected, forfeiting the matched-pair advantage and occupying extra PCB area versus a single-device solution.

Is thermal derating required for continuous operation at 85°C ambient?

Yes - at T_A = 85°C, power dissipation must be reduced to 210 mW per the derating curve (300 mW × [1 − (85 − 25)/417]). This ensures junction temperature stays within the −65 °C to +150 °C rating, assuming standard FR-4 mounting with recommended pad layout.

Does AZ23C3V6-7 meet AEC-Q200 requirements for passive components?

No - AZ23C3V6-7 is qualified to AEC-Q101 (for discrete semiconductors), not AEC-Q200 (for passive components). It meets automotive-grade reliability requirements including HBM ESD 8 kV, operating temperature −65 °C to +150 °C, and IATF 16949 manufacturing controls - but formal AEC-Q200 certification does not apply to Zener diodes.
