Diodes Incorporated AZ23C5V6Q-7-F

Overview

AZ23C5V6Q-7-F from Diodes Incorporated is a dual common-anode 300 mW surface-mount Zener diode with nominal zener voltage 5.6 V (±5%), 40 Ω zener impedance at 5 mA, +0.020 %/°C temperature coefficient, and reverse leakage <0.1 µA at 1.0 V - used for precision voltage reference and overvoltage clamping in low-power analog sensor signal conditioning circuits.

For engineers reviewing the AZ23C5V6Q-7-F datasheet, AZ23C5V6Q-7-F pinout, AZ23C5V6Q-7-F application, or AZ23C5V6Q-7-F equivalent, key selection criteria include dual-zener topology, SOT-23 package thermal resistance (417 °C/W), common-anode configuration, zener voltage tolerance, and RoHS-compliant matte tin plating.

Technical Context

This dual Zener diode integrates two identical 5.6 V zener elements sharing a single anode terminal, enabling symmetrical bidirectional clamping or dual-rail reference generation in compact space-constrained designs. Its common-anode architecture supports rail-to-rail voltage regulation without requiring separate cathode routing.

The device operates across –65 °C to +150 °C, with thermal resistance of 417 °C/W on FR4 PCBs using recommended pad layout, and maintains stable breakdown behavior under 5 mA test current with <40 Ω dynamic impedance - critical for low-noise feedback paths in LDOs and ADC reference buffers.

FAQ

What is the maximum continuous reverse current this device can handle without exceeding its 300 mW rating?

At nominal 5.6 V zener voltage, the absolute maximum continuous reverse current is 53.6 mA (300 mW ÷ 5.6 V). However, derating per the power derating curve is required above 25 °C ambient - e.g., only ~35 mA is permissible at 70 °C ambient due to thermal resistance of 417 °C/W on standard FR4.

Can AZ23C5V6Q-7-F be used as a replacement for a single 5.6 V Zener diode?

Yes - either cathode (Pin 2 or Pin 3) can be used independently with the common anode (Pin 1) grounded, delivering identical 5.6 V ±5% regulation as a standalone Zener. The unused cathode must be left floating or tied to the same potential as the active cathode to avoid leakage path interference.

Does the "Q" in AZ23C5V6Q-7-F indicate a specific packaging or testing variant?

Yes - the "Q" suffix denotes qualification to AEC-Q200 Grade 2 (–40 °C to +105 °C operating range) and enhanced reliability screening including HTOL and temperature cycling, making it suitable for automotive body electronics and industrial control applications beyond standard commercial-grade parts.

How does the +0.020 %/°C temperature coefficient affect performance in a 0–70 °C ambient range?

Over 0–70 °C, the zener voltage shifts by +14 mV (5.6 V × 0.0002 × 70), resulting in a total variation of ±5% tolerance plus ±0.14% TC drift - well within ±6% overall stability required for most non-precision reference and clamping functions.
