Diodes Incorporated AZ23C6V2-7

Overview

AZ23C6V2-7 from Diodes Incorporated is a dual common-anode surface-mount Zener diode with nominal 6.2 V zener voltage (5.8–6.6 V range), 300 mW power dissipation, and ±5% matching between the two zeners in one SOT23 package. It delivers precise voltage reference and overvoltage protection in space-constrained DC biasing, power supply feedback, and analog signal conditioning circuits.

For engineers reviewing the AZ23C6V2-7 datasheet, AZ23C6V2-7 pinout, AZ23C6V2-7 application, or AZ23C6V2-7 equivalent, key selection criteria include matched zener voltage tolerance, low dynamic impedance (10 Ω @ 5 mA), positive temperature coefficient (+0.030 %/°C), and JEDEC-qualified reliability for industrial and automotive-derivative designs.

Technical Context

This dual Zener operates in reverse breakdown mode with both anodes internally tied, enabling symmetrical clamping or bidirectional reference generation from a single node. Its 10 Ω zener impedance at 5 mA ensures stable regulation under moderate load transients.

The device exhibits a +0.030 %/°C temperature coefficient and maintains ≤5% inter-diode V_Z mismatch-critical for differential sensing, rail-splitting, and precision comparator threshold setting where tracking between dual elements is required.

FAQ

What is the maximum continuous reverse current the AZ23C6V2-7 can handle at 25°C?

The AZ23C6V2-7 is rated for 300 mW total power dissipation. At its nominal 6.2 V zener voltage, this corresponds to a maximum continuous reverse current of approximately 48 mA (300 mW ÷ 6.2 V). Derating applies above 25°C per the published power derating curve, reaching zero dissipation at ~150°C junction temperature.

Can AZ23C6V2-7 be used as a single Zener by leaving one cathode unconnected?

No - the device is internally configured as a common-anode dual Zener (Pins 1 and 3 tied). Leaving Pin 2 or Pin 3 floating violates recommended biasing and may cause unpredictable leakage or thermal instability. Both cathodes must be actively biased in reverse to operate correctly; unused elements should be terminated per design requirements.

Is the 5% V_Z matching guaranteed over temperature or only at 25°C?

The ≤5% ΔV_Z specification is measured at T_A = 25°C under standard test conditions. While the matched tempco (+0.030 %/°C) ensures correlated drift, the datasheet does not guarantee the 5% matching holds across the full –65°C to +150°C operating range. System-level validation is required for wide-temperature applications demanding tight tracking.

Does AZ23C6V2-7 meet automotive qualification standards out of the box?

The commercial-grade AZ23C6V2-7 is AEC-Q101 qualified for ESD (HBM 8 kV, MM 400 V) and JEDEC reliability, but it is not automotive-qualified by default. For automotive applications, the Q-suffix variant (e.g., AZ23C6V2Q-7-F) must be selected - it undergoes full AEC-Q101 stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities.
