Product details

Overview

AZ23C7V5-7-F from Diodes Incorporated is a dual common-anode 300 mW surface-mount Zener diode with nominal Zener voltage 7.5 V (7.0–7.9 V range), 7.0 Ω typical Zener impedance at 5 mA, +0.050 %/°C temperature coefficient, and 5.0 V minimum reverse voltage at 0.1 µA leakage. It provides precision voltage reference and overvoltage clamping in compact SOT23 packages for power supply regulation and signal conditioning circuits.

For engineers reviewing the AZ23C7V5-7-F datasheet, AZ23C7V5-7-F pinout, AZ23C7V5-7-F application, or AZ23C7V5-7-F equivalent, key selection criteria include dual-Zener matching (≤5% ΔV_Z), low thermal resistance (417 °C/W), JEDEC-qualified reliability, AEC-Q101 HBM ESD rating (8 kV), and RoHS-compliant green packaging.

Technical Context

This dual Zener diode integrates two identical Zener elements sharing a common anode terminal, enabling bidirectional voltage clamping or dual-reference generation in a single SOT23 footprint. Its matched breakdown characteristics support differential sensing and rail-to-rail protection schemes.

The device operates across –65 °C to +150 °C, with thermal derating beginning above 25 °C ambient per the defined power curve. Its 7.0 Ω Zener impedance at I_ZT = 5 mA ensures stable regulation under moderate load transients, while the +0.050 %/°C TC minimizes drift in temperature-varying environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	7.0 V to 7.9 V at I_ZT = 5 mA - defines usable regulation band for precision reference design
Zener Impedance	7.0 Ω typical at I_ZT = 5 mA - low dynamic resistance enables tight voltage regulation under varying current
Temperature Coefficient	+0.050 %/°C - positive TC allows predictable drift compensation in multi-device bias networks
Max Power Dissipation	300 mW - sets absolute DC/peak pulse power limit on FR-4 PCB with recommended pad layout
Reverse Voltage	≥5.0 V at I_R = 0.1 µA - ensures reliable blocking before Zener conduction onset
Thermal Resistance	417 °C/W junction-to-ambient - determines allowable ambient rise for safe 300 mW operation
ESD Rating	HBM 8 kV, IEC 61000-4-2 Air 15 kV - supports robust handling and system-level surge immunity

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 (Common)	Shared anode connection for both Zener diodes; must be biased negative relative to cathodes for conduction

Pin 3	Cathode 2	Zener element 2 cathode; conducts when voltage at Pin 3 exceeds Pin 1 by ≥7.0 V; matched to Cathode 1 within ≤5% ΔV_Z

Key Features

Feature	Design Value
Dual Zeners, Common Anode	Enables symmetrical bidirectional clamping or dual independent reference outputs from one footprint
≤5% ΔV_Z Matching	Guarantees tight tracking between two Zener elements for differential or ratiometric applications
JEDEC-High Reliability Qualified	Validated per AEC-Q101 stress tests - suitable for industrial and automotive-adjacent systems requiring proven robustness
Halogen & Antimony Free	Meets "Green" definition (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) for environmentally constrained designs
SOT23 Tape & Reel (3,000 pcs)	Supports high-speed automated placement without manual handling or orientation concerns

Applications

Power Supply Rail Clamp

ADC Reference Stabilization

Use Scenario: Protecting 3.3 V or 5 V logic rails from transient overvoltage events in industrial PLC I/O modules.

IC Role / Device Role: Bidirectional shunt clamp limiting voltage excursions to ±7.5 V relative to common ground plane.

Use Value: Prevents latch-up or damage to downstream CMOS interfaces using only one SOT23 device instead of discrete dual-diode solutions.

Use Scenario: Providing stable 7.5 V reference for 12-bit SAR ADCs in sensor signal conditioning front-ends.

IC Role / Device Role: Low-impedance Zener source buffering high-impedance DAC or op-amp feedback nodes.

Use Value: Achieves <±0.5% reference stability over –40 °C to +85 °C due to matched TC and low ZZT.

Differential Voltage Monitor

Low-Cost Dual Threshold Detector

Use Scenario: Detecting out-of-tolerance voltage differentials between two 5 V supplies in redundant power systems.

IC Role / Device Role: Common-anode configuration compares |V_A − V_B| against 7.5 V threshold via simple resistor divider network.

Use Value: Eliminates need for op-amp comparators or dedicated monitor ICs in cost-sensitive monitoring paths.

Use Scenario: Generating upper/lower trip points for battery voltage window detection in portable medical devices.

IC Role / Device Role: Two independently biased cathodes create distinct 7.5 V thresholds referenced to shared anode node.

Use Value: Enables accurate 7.0–7.9 V hysteresis band with <1% matching error-no calibration required.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-Zener reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C7V5-7-F	Single Zener, same V_Z range and SOT23 package; no dual-element matching	Only supports single-rail clamping or reference; cannot implement differential or matched-pair functions	Select when only one Zener function is needed and board space permits separate devices
DZ23C7V5-7-F	Same dual-Zener architecture but common-cathode configuration (Pin 1 = cathode, Pins 2/3 = anodes)	Requires inverted PCB layout and reversed biasing; incompatible pinout for drop-in replacement	Choose when existing schematics use common-cathode topology or require inverted polarity clamping

Compared with BZX84-C7V5-7-F and DZ23C7V5-7-F, AZ23C7V5-7-F uniquely delivers matched dual-Zener performance in common-anode topology-enabling compact differential sensing, rail-symmetric protection, and reduced component count where bidirectional voltage control is required.

FAQ

What is the maximum continuous Zener current for AZ23C7V5-7-F at 25°C ambient?

The device is rated for 300 mW total power dissipation. At nominal 7.5 V Zener voltage, this corresponds to a maximum average Zener current of 40 mA (300 mW ÷ 7.5 V). Derating applies above 25°C per the published power curve, reducing allowable current linearly with rising ambient temperature.

Can AZ23C7V5-7-F be used in automotive applications?

AZ23C7V5-7-F is qualified to AEC-Q101 and JEDEC high-reliability standards, making it suitable for automotive-adjacent systems. For full automotive qualification (e.g., PPAP, IATF 16949 manufacturing), the Q-suffix variant AZ23C7V5Q-7-F must be specified per Diodes' automotive product listing.

How is the 5% ΔV_Z matching verified between the two Zener elements?

ΔV_Z ≤ 5% is guaranteed by factory binning during final test. Each unit undergoes simultaneous measurement of both Zener voltages at I_ZT = 5 mA, and only units meeting the matching specification are released as AZ23C7V5-7-F. This data is not provided per unit but assured statistically across the production lot.

Does AZ23C7V5-7-F support reverse-biased operation as a standard diode?

No. The device is optimized exclusively for Zener breakdown operation. Forward conduction (anode-to-cathode) is not characterized or guaranteed beyond typical silicon diode behavior (~0.7 V drop), and forward current capability is limited by the 300 mW power rating-not designed for rectification or switching roles.
