AZ23C22-7-G

Overview

The AZ23C22-7-G is a dual common anode Zener diode array manufactured by Diodes Incorporated. It features a nominal Zener voltage of 22 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and a maximum reverse leakage current of 100 nA at 17 V. The Zener impedance is specified at 55 Ohms. It operates within a temperature range of -65°C to +150°C and is housed in an SOT-23-3 surface-mount package.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Automotive-grade reliability certified under AEC-Q101 standards
• Low leakage current characteristics for precision applications

Applications

• Voltage reference circuits requiring stable dual references
• ESD protection in automotive electronic modules
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix '-G' against the manufacturer's latest documentation to confirm RoHS compliance status and exact pinout compatibility. Ensure the ordering code matches the required packaging format, such as tape and reel or cut tape, as availability varies by distributor. Cross-reference the part number with official distributors to confirm current production status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener array with a 22 V breakdown voltage is required in a compact SOT-23-3 footprint. The AEC-Q101 qualification makes it suitable for automotive environments where high thermal stability and low leakage are critical. Compare the 300 mW power rating against the expected dissipation in the target application to ensure safe operating limits are not exceeded during peak conditions.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from Diodes Incorporated. The series offers various voltage options in standardized packages to simplify BOM management. The AZ23C22 variant specifically targets applications needing two independent Zener references sharing a common anode terminal within a minimal surface-mount form factor.

Replacement Considerations

Equivalent parts include Vishay's AZ23C22-E3-18 and AZ23C22-G3-18, which share identical electrical specifications and pin configurations. Verify mechanical dimensions and thermal characteristics when substituting to ensure board compatibility.
