Product details

Overview

AZ23C7V5-7 from Diodes Incorporated is a dual common-anode 7.5V Zener diode pair in SOT23 package, rated for 300mW total power dissipation, with ±5% matching between zener voltages and 7.0Ω typical zener impedance at 5mA. It delivers precision voltage reference and overvoltage clamping in space-constrained DC bias and protection circuits.

For engineers reviewing the AZ23C7V5-7 datasheet, AZ23C7V5-7 pinout, AZ23C7V5-7 application, or AZ23C7V5-7 equivalent, key selection criteria include matched dual-zener tolerance, low thermal resistance (417°C/W), JEDEC-qualified reliability, automotive-grade availability (Q-suffix), and SOT23-compatible automated assembly compatibility.

Technical Context

This dual Zener operates in common-anode configuration, enabling independent cathode referencing for bidirectional voltage regulation or differential clamping. Each diode exhibits a nominal 7.5V breakdown (7.0–7.9V range) with +0.050%/°C temperature coefficient and 50Ω maximum zener impedance at IZK = 1.0mA.

Thermal performance is defined for FR-4 PCB mounting per recommended pad layout, supporting continuous operation from –65°C to +150°C. The device meets AEC-Q101 (HBM 8kV, MM 400V) and IEC 61000-4-2 (air 15kV, contact 8kV) ESD requirements, and is fully RoHS-compliant, halogen-free, and lead-free.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage	7.0–7.9 V at I_ZT = 5 mA - defines tight regulation window for reference or clamp applications
Power Dissipation	300 mW total - supports dual-diode operation without derating on standard FR-4 layouts
Zener Impedance	7.0 Ω typical at 5 mA - ensures stable output under dynamic load transients
Temperature Coefficient	+0.050 %/°C - enables predictable drift compensation in temperature-varying environments
Reverse Leakage	<0.1 µA at 5.0 V - guarantees minimal standby current in high-impedance bias networks
Thermal Resistance	417 °C/W junction-to-ambient - informs PCB thermal design for sustained 300mW operation
ESD Rating	HBM 8 kV, IEC 61000-4-2 contact 8 kV - qualifies for robust handling in industrial and automotive assembly lines

Pinout & Package

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

Applications

Industrial Sensor Biasing

USB Port Overvoltage Protection

Use Scenario: Providing stable 7.5V reference for analog front-end amplifiers in temperature/pressure transducers.

IC Role / Device Role / Timing Role: Dual-Zener voltage reference and noise-filtering shunt element.

Use Value: Matched V_Z ensures consistent offset calibration across dual-channel sensors; low Z_Z maintains accuracy under varying load currents.

Use Scenario: Clamping D+ and D− data lines against ESD and surge events in USB 2.0 host ports.

IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor with common-ground return.

Use Value: Common-anode architecture allows single-device dual-line protection without cross-coupling; 8kV HBM rating exceeds IEC 61000-4-2 Level 4.

Automotive CAN Transceiver Bias

Programmable Logic Supply Clamp

Use Scenario: Generating regulated 7.5V bias for isolated CAN FD transceiver VIO rails in body control modules.

IC Role / Device Role / Timing Role: Precision voltage clamp and local reference generator.

Use Value: AEC-Q101 qualification and –65°C to +150°C operation ensure reliability in under-hood environments; matched diodes simplify dual-supply monitoring.

Use Scenario: Limiting FPGA I/O bank voltage during hot-swap or brown-out conditions in telecom baseband cards.

IC Role / Device Role / Timing Role: Fail-safe rail clamp preventing logic-level corruption during supply instability.

Use Value: 300mW rating sustains short-duration surges; low leakage (<0.1 µA) avoids loading during normal operation.

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-C7V5	Single 7.5V Zener in SOT23; no dual-element or matching spec	Requires two devices and external matching verification for dual-rail use	Choose when only one reference is needed or board area permits discrete duplication
DZ23C7V5	Same dual-Zener specs but common-cathode configuration (Pin 1 = cathode, Pins 2/3 = anodes)	Inverts circuit topology-requires redesign of ground/reference node connections	Prefer when existing schematics use common-cathode layout or require anode-switched clamping

Compared with BZX84-C7V5 and DZ23C7V5, AZ23C7V5-7 uniquely provides factory-matched dual 7.5V Zeners in common-anode topology-reducing component count, eliminating manual matching, and simplifying PCB routing for symmetric voltage referencing.

FAQ

What is the maximum continuous power dissipation for AZ23C7V5-7?

AZ23C7V5-7 has a maximum power dissipation of 300 mW at TA = 25°C on a standard FR-4 PCB with Diodes' recommended pad layout. Derating begins linearly above 25°C at 0.72 mW/°C, reaching zero at 150°C ambient per the published derating curve.

How is the "DC" marking interpreted on the SOT23 package?

The "DC" top-side marking identifies the AZ23C7V5 variant per Diodes' standardized coding scheme (see DS18003 Rev. 18–2, page 3). It is not a date code-"DC" corresponds exclusively to the 7.0–7.9V Zener voltage range and confirms compliance with the AZ23C7V5 electrical specification.

Can AZ23C7V5-7 be used in place of a single Zener diode?

Yes-only Cathode A (Pin 2) and the common Anode (Pin 1) need connection; Cathode B (Pin 3) remains unconnected. However, doing so forfeits the matched-pair benefit and uses the same footprint as a single-Zener SOT23, making it viable only where future dual-use or stock rationalization is planned.

Does AZ23C7V5-7 meet automotive qualification standards?

The commercial-grade AZ23C7V5-7 is AEC-Q101 qualified per Diodes' internal stress testing and JEDEC standards. For full automotive PPAP support and IATF 16949-manufactured lots, specify the Q-suffix version (e.g., AZ23C7V5Q-7-F), listed in Diodes' Automotive Products portal.
