Product details
Overview
AZ23C5V6-7 from Diodes Incorporated is a dual common-anode 300mW surface-mount Zener diode with nominal zener voltage 5.6V (5.2–6.0V range), 40Ω max zener impedance at 5mA, +0.020%/°C temperature coefficient, and 1.0V min reverse voltage at 0.1µA leakage. It provides precision voltage reference and overvoltage clamping in space-constrained power management circuits.
For engineers reviewing the AZ23C5V6-7 datasheet, AZ23C5V6-7 pinout, AZ23C5V6-7 application, or AZ23C5V6-7 equivalent, key selection criteria include dual-zener matching tolerance (≤5% ΔVZ), SOT23 thermal resistance (417°C/W), JEDEC-qualified reliability, and automotive-grade availability via Q-suffix variants.
Technical Context
This dual Zener operates in common-anode configuration, enabling bidirectional voltage regulation or complementary reference generation from a single package. Each cathode terminal delivers independent breakdown behavior with matched VZ tracking within ±5% across the pair.
Designed for automated SMT assembly, it supports stable operation from –65°C to +150°C with 300mW total power dissipation and derating above 25°C per the published curve. Its low 40Ω dynamic impedance at 5mA ensures tight regulation under moderate load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage Range | 5.2–6.0 V at IZT = 5 mA - defines usable regulation window for precision biasing |
| Zener Impedance | 40 Ω max at IZT = 5 mA - ensures low output impedance for stable reference voltage |
| Temperature Coefficient | +0.020 %/°C - enables predictable VZ drift compensation in wide-temp environments |
| Max Power Dissipation | 300 mW - sets absolute thermal limit on PCB with standard FR-4 pad layout |
| Reverse Voltage | 1.0 V min at IR = 0.1 µA - guarantees high off-state blocking for low-leakage sensing |
| Thermal Resistance | 417 °C/W junction-to-ambient - determines required board copper area for safe continuous operation |
Pinout & Package
Package: SOT23 - molded green plastic, UL 94V-0 rated, 0.008 g weight, matte tin-plated alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Common anode node | Shared current return path for both Zeners; must be connected to lowest potential in circuit |
| Cathode A (Pin 2) | Zener A cathode | Provides first regulated breakdown voltage (5.2–6.0 V) when forward-biased relative to Pin 1 |
| Cathode B (Pin 3) | Zener B cathode | Provides second regulated breakdown voltage (identical spec) with ≤5% VZ mismatch vs. Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener Matching | ΔVZ ≤ 5% between cathodes - eliminates need for external trimming in differential reference designs |
| Automated Assembly Support | SOT23 footprint with JEDEC-compliant pad layout - ensures high-yield reflow and placement accuracy |
| High Reliability Qualification | AEC-Q101 qualified (HBM 8 kV, MM 400 V) - suitable for automotive and industrial control systems |
| Green Compliance | Halogen-free, antimony-free, RoHS 3 compliant - meets global environmental compliance mandates without performance trade-off |
Applications
| Power Supply Monitoring | Overvoltage Protection |
|---|---|
Use Scenario: Detecting undervoltage/overvoltage conditions in 5V rail monitoring circuits. IC Role / Device Role / Timing Role: Dual-Zener reference generating trip thresholds for comparator inputs. Use Value: Matched VZ enables symmetric hysteresis windows without external resistor networks. |
Use Scenario: Clamping transient spikes on microcontroller I/O lines exposed to ESD or inductive kickback. IC Role / Device Role / Timing Role: Bidirectional shunt clamp limiting voltage excursions to ±6V. Use Value: Common-anode topology allows single-device protection of push-pull signal paths. |
| Temperature-Compensated Reference | Low-Power Sensor Biasing |
Use Scenario: Providing stable bias to analog front-end amplifiers in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Precision voltage reference with +0.020%/°C TC minimizing drift over –40°C to +85°C. Use Value: Enables <±1% reference stability without external compensation components. |
Use Scenario: Supplying regulated bias to MEMS pressure sensor bridges operating from 3.3V supplies. IC Role / Device Role / Timing Role: Low-current Zener source delivering 5.6V at <100µA quiescent draw. Use Value: 0.1µA leakage threshold ensures minimal loading on ultra-low-power LDO outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79-C5V6 (Nexperia) | Single Zener, DO-35 through-hole, 500mW, ±5% VZ tolerance, no dual-element matching | Lacks common-anode dual configuration; requires two devices for matched reference | Select only if through-hole assembly is mandatory and dual-element matching is unnecessary |
| DZ23C5V6 (Diodes Inc.) | Common-cathode dual Zener, same SOT23 package, identical VZ range but inverted polarity | Requires reversed PCB layout; used where cathode-referenced clamping is preferred | Choose when system ground references demand cathode-common architecture instead of anode-common |
Compared with BZX79-C5V6 and DZ23C5V6, AZ23C5V6-7 uniquely delivers matched dual-anode Zeners in SMT format-enabling compact, thermally coupled reference generation unattainable with discrete or cathode-common alternatives.

FAQ
What is the maximum continuous power dissipation for AZ23C5V6-7 at 70°C ambient?
At 70°C ambient, the device's power derating curve reduces its maximum allowable dissipation to approximately 225 mW. This is calculated using the 417°C/W thermal resistance and the 150°C max junction temperature: (150 – 70) / 417 ≈ 0.192 W. Derating begins linearly at 25°C, reaching zero at 150°C.
Can AZ23C5V6-7 be used as a single Zener by leaving one cathode unconnected?
Yes - either cathode (Pin 2 or Pin 3) may be used independently while the other remains floating, provided the common anode (Pin 1) is properly biased. The unused cathode exhibits no significant leakage or parasitic conduction, maintaining full specification compliance for the active Zener element.
Is there a recommended PCB pad layout for optimal thermal performance?
Yes - Diodes specifies a minimum pad layout: 2.0 mm × 0.9 mm solder pad (C × Y), with 1.35 mm × 2.9 mm courtyard (X1 × Y1). Copper pour under the thermal pad is not supported; instead, use thermal relief traces to balance solderability and heat dissipation per the official SOT23 outline document.
Does AZ23C5V6-7 meet AEC-Q200 stress testing requirements?
No - AZ23C5V6-7 is qualified to AEC-Q101 (for discrete semiconductors), not AEC-Q200 (for passive components). For AEC-Q200 compliance, Diodes offers automotive-grade variants with Q-suffix (e.g., AZ23C5V6Q-7-F), which undergo additional temperature cycling, humidity, and mechanical shock tests per the passive component standard.
