AZ23C6V8-7

Overview

The AZ23C6V8-7 is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common anode configuration with two independent Zener elements sharing a single anode terminal. The nominal Zener voltage is 6.8 V, with a specified range of 6.4 V to 7.2 V at a test current of 5.0 mA. Maximum Zener impedance is 8.0 Ω at the test current and 150 Ω at a low current of 1.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Common anode configuration allows efficient biasing and circuit integration.
• High reliability qualification compliant with JEDEC standards and AEC-Q101 ESD ratings.

Applications

• Voltage reference circuits requiring matched dual references.
• Transient voltage suppression in signal lines.
• Clamping applications for protecting sensitive input stages.

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard commercial version uses the -7-F suffix and comes in tape and reel packaging with a quantity of 3,000 units. Automotive-grade variants are available with a Q-suffix for applications requiring strict change control and IATF 16949 manufacturing certification. Confirm the exact part number matches the required voltage tolerance and package type before finalizing orders.

Selection Notes

Select this component when a dual Zener solution with a common anode topology is required. The 6.8 V nominal voltage fits within the mid-range of the series, offering a typical temperature coefficient of +0.045 %/°C. Ensure the application can accommodate the 300 mW power dissipation limit and that the SOT-23 footprint aligns with the PCB layout guidelines provided in the datasheet.

Part Context

This part belongs to the AZ23C series of 300 mW dual surface mount Zener diodes from Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, all utilizing the same SOT-23 mechanical outline. The AZ23C6V8-7 specifically addresses needs for 6.8 V regulation or protection in a minimal footprint form factor.

Replacement Considerations

The DZ23C6V8-7 serves as a functional substitute but utilizes a common cathode configuration instead of common anode. Direct pin-to-pin replacement requires verifying circuit polarity compatibility. Other voltages in the AZ23C series share the same package but differ electrically.
