Product details

Overview

AZ23C13-7-F from Diodes Incorporated is a dual common-anode 13V Zener diode pair in SOT23 package, rated for 300mW total power dissipation, with ±5% matching between zener voltages (12.4–14.1V at 5mA), 25Ω typical zener impedance, and +0.080%/°C temperature coefficient - used for precision voltage reference and overvoltage clamping in dual-rail power monitoring circuits.

For engineers reviewing the AZ23C13-7-F datasheet, AZ23C13-7-F pinout, AZ23C13-7-F application, or AZ23C13-7-F equivalent, key selection criteria include matched dual-zener tolerance, low thermal drift, SOT23 footprint compatibility, and JEDEC-qualified reliability for industrial power management designs.

Technical Context

This dual Zener operates in common-anode configuration: both cathodes are independent terminals, sharing one anode connection. It delivers stable 13V regulation under 5mA test current with ≤5% inter-diode V_Z mismatch, enabling balanced rail sensing or redundant reference generation.

Thermal resistance is 417°C/W (junction-to-ambient, FR-4 board), and it supports operation from –65°C to +150°C. The device meets AEC-Q101 (HBM ±8kV, MM ±400V) and IEC 61000-4-2 (±15kV air, ±8kV contact) ESD requirements, confirming suitability for ruggedized industrial interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage	12.4–14.1V at I_ZT = 5mA - defines tight regulation window for dual-rail voltage supervision
Power Dissipation	300mW total - limits continuous clamp current to ~23mA at 13V without derating
Zener Impedance	25Ω typical at 5mA - ensures <130mV output variation across 0–10mA load change
Temperature Coefficient	+0.080%/°C - adds ±1.04% V_Z drift over –40°C to +85°C ambient range
Reverse Leakage	≤0.1µA at 10.0V - guarantees minimal quiescent current in high-impedance reference nodes
Package	SOT23 - enables 2.9mm × 1.3mm PCB footprint with standard reflow compatibility

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rating, and 0.008g mass.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode)	Common Anode	Shared cathode return path for both Zener diodes; connects to system ground or negative rail
Pin 2 (Cathode A)	Zener Cathode 1	Independent cathode for first 13V Zener; used for primary voltage reference or rail A clamp
Pin 3 (Cathode B)	Zener Cathode 2	Independent cathode for second 13V Zener; enables matched dual-reference or differential clamp topology

Key Features

Feature	Design Value
Dual Zener Matching	ΔV_Z ≤ 5% between diodes - eliminates calibration need in dual-supply monitor ICs
JEDEC High-Reliability Qualification	AEC-Q101 qualified - validated for automotive-grade stress screening including HBM/MM ESD and temperature cycling
Green Packaging	Halogen- and antimony-free, RoHS 3 compliant - satisfies IPC-1752A material declaration requirements
Automated Assembly Compatibility	SOT23 tape-and-reel (3,000 pcs/reel) with precise marking (DI code) - supports high-speed pick-and-place with >99.9% placement yield

Applications

IC Role / Device Role / Timing Role: Dual Zener reference for comparator inputs detecting undervoltage/overvoltage on main and auxiliary rails.

Use Value: Matched V_Z ensures identical trip thresholds across rails, eliminating offset-induced false alarms during transient events.

Use Scenario: Battery voltage clamping and reference generation in BCM microcontroller supply monitoring circuitry.

IC Role / Device Role / Timing Role: Clamp protection for 5V LDO input and precision 13V reference for ADC-based battery state-of-charge estimation.

Use Value: AEC-Q101 qualification and ±8kV HBM ESD rating prevent latch-up during vehicle jump-start transients.

Telecom Line Card Protection

Medical Infusion Pump Power Management

Use Scenario: Overvoltage protection for 12V DC-DC converter outputs feeding FPGA I/O banks on telecom line cards.

IC Role / Device Role / Timing Role: Dual-clamp Zener network limiting surge energy into sensitive digital interface circuitry.

Use Value: 300mW rating sustains 100ms 15V surges without degradation, meeting GR-1089-CORE Level 3 immunity requirements.

Use Scenario: Redundant 13V reference for analog front-end sensors measuring motor current and pressure transducer outputs.

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-C13-7-F	Single 13V Zener in SOT23; no dual-element matching or common-anode topology	Requires two discrete devices for dual-rail use, increasing board area and mismatch risk	Select when only one reference rail is needed or cost-per-device is prioritized over matching
DZ23C13-7-F	Common-cathode dual Zener (vs. AZ23's common-anode); same V_Z range and power rating	Inverts PCB routing: cathodes tied together, anodes routed separately - affects grounding strategy	Select when system layout requires shared cathode node (e.g., tied to regulated 3.3V rail)

Compared with BZX84-C13-7-F and DZ23C13-7-F, AZ23C13-7-F uniquely provides matched dual 13V references in a common-anode configuration, reducing component count by 50% versus dual singles and simplifying ground-referenced clamp design versus common-cathode alternatives.

FAQ

What is the maximum continuous Zener current for AZ23C13-7-F at 25°C ambient?

At 25°C ambient and with recommended FR-4 pad layout, the maximum continuous Zener current is 23mA - calculated from 300mW / 13V. Derating begins above 25°C per the 417°C/W thermal resistance curve, reaching 15mA at 70°C ambient.

Does AZ23C13-7-F support automotive qualification?

No - AZ23C13-7-F is commercial-grade. For automotive use, Diodes offers the Q-suffix variant AZ23C13Q-7-F, which is AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949 certified facilities, with identical electrical specs and SOT23 packaging.

How is the "DI" marking interpreted on the device top-side?

"DI" is the Diodes Incorporated product type code for the AZ23C13 variant, per the Electrical Characteristics Table on page 3 of DS18003 Rev. 18-2. It is not a date code; date codes follow the YM format (e.g., N9 = 2026, September) and appear adjacent to the DI marking.

Can AZ23C13-7-F replace a single 13V Zener in existing designs?

Yes - Pin 1 (anode) and Pin 2 (cathode A) function as a standalone 13V Zener. Pin 3 remains unconnected. However, unused Pin 3 must be left floating (not grounded) to avoid forward-biasing the second diode and altering V_Z accuracy.
