Diodes Incorporated AZ23C5V1Q-7-F

Overview

AZ23C5V1Q-7-F from Diodes Incorporated is a dual Zener diode in common-anode SOT23 package, rated for 300 mW total power dissipation, with nominal zener voltage 5.1 V (4.8–5.4 V range), ±0.005 %/°C temperature coefficient, and 60 Ω zener impedance at 5 mA test current. It serves precision voltage reference and overvoltage protection functions in low-power analog monitoring circuits.

For engineers reviewing the AZ23C5V1Q-7-F datasheet, AZ23C5V1Q-7-F pinout, AZ23C5V1Q-7-F application, or AZ23C5V1Q-7-F equivalent, key selection criteria include dual-zener matching tolerance (≤5% ΔV_Z), automotive-grade AEC-Q101 qualification (Q-suffix), JEDEC high-reliability compliance, and SOT23 thermal resistance of 417 °C/W on FR-4 board.

Technical Context

This device integrates two matched Zener diodes sharing a common anode terminal, enabling bidirectional clamping or dual-reference generation from a single footprint. Its design supports stable regulation under low-current conditions (I_ZT = 5 mA, I_ZK = 1 mA) and exhibits minimal voltage drift across –65 °C to +150 °C operating range.

The common-anode configuration allows independent cathode access for asymmetric voltage referencing-e.g., generating +5.1 V and –5.1 V rails from a split supply-or differential clamping in signal conditioning paths where matched breakdown characteristics are critical.

FAQ

What does the 'Q' suffix in AZ23C5V1Q-7-F signify?

The 'Q' suffix denotes AEC-Q101 qualification, confirming that this part has undergone stress testing per the Automotive Electronics Council standard for discrete semiconductors-including HBM ESD (8 kV), temperature cycling, and high-temperature reverse bias. It is manufactured in IATF 16949-certified facilities and supports PPAP documentation for automotive OEMs.

Can AZ23C5V1Q-7-F replace a single Zener diode in a circuit?

Yes, but only one of its two Zener elements should be used-connect the common anode to circuit ground or reference potential and use either cathode as the active Zener terminal. The unused cathode must remain unconnected or tied to the same potential as the anode to avoid leakage path interference.

How is the 5% ΔV_Z matching verified between the two Zeners?

Diodes Incorporated measures both Zener voltages at I_ZT = 5 mA on the same die during final test. The absolute difference divided by the average V_Z is guaranteed ≤5% for every unit shipped. This matching is process-controlled and documented in DS18003 Rev. 18–2, page 1.

Does the SOT23 package support reflow soldering per JEDEC J-STD-020?

Yes-the SOT23 package is rated for moisture sensitivity level 1 and qualified for standard Pb-free reflow profiles (peak 260 °C, 20–40 sec). The matte tin finish ensures reliable wetting, and the 0.008 g mass minimizes thermal gradient risks during profile ramp-up.
