AZ23C39-7-G

Overview

The AZ23C39-7-G is a dual common anode Zener diode array manufactured by Diodes Incorporated. It features a nominal Zener voltage of 39 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 32 V. The Zener impedance is specified at 90 Ohms, tested at 5 mA. 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 with AEC-Q100 qualification
• Lead-free construction with matte tin finish

Applications

• Voltage reference circuits requiring dual polarity or split supplies
• Transient voltage suppression in automotive electronics
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the suffix 'G' indicates lead-free compliance and halogen-free status as per manufacturer mechanical data. Confirm the specific revision level against the latest datasheet to ensure compatibility with RoHS directives. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a dual Zener array with a 39 V breakdown is required in a compact SOT-23-3 footprint. Ensure the 300 mW power rating suffices for the expected thermal environment. Verify that the ±5% voltage tolerance meets the precision requirements of the target application compared to tighter tolerance alternatives.

Part Context

This part belongs to the AZ23C series of dual Zener diode arrays from Diodes Incorporated. The series offers various voltage options in a standardized small outline package. The '7-F' suffix typically denotes standard reel packaging, while 'G' specifies environmental compliance attributes such as lead-free terminals.

Replacement Considerations

The AZ23C39-7-F is a functionally equivalent alternative within the same series, differing primarily in packaging specifications rather than electrical performance. Other manufacturers offer similar SOT-23-3 dual Zener arrays, but direct pin-compatible substitutes require verification of voltage tolerance and impedance parameters.
