AZ23C6V2-7-F

Overview

The AZ23C6V2-7-F 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 silicon junctions within a single case. The nominal Zener voltage is 6.2 V, operating within a range of 5.8 V to 6.6 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, supported by a typical thermal resistance of 417 °C/W from junction to ambient air. The device exhibits a maximum Zener impedance of 10 Ω at the test current and 200 Ω at a low current of 1.0 mA. It maintains a tight voltage matching between the two diodes (ΔVz ≤ 5%) and operates across a temperature range of -65°C to +150°C.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
• High reliability qualification compliant with JEDEC standards and AEC-Q101 ESD ratings.
• Environmentally friendly construction featuring lead-free, halogen-free, and antimony-free materials.

Applications

• Voltage reference circuits requiring matched dual references.
• Over-voltage protection stages in signal conditioning paths.
• Clamping applications in high-reliability electronic assemblies.

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to commercial grade qualification and tape & reel packaging containing 3,000 units per carrier. Confirm that the component meets RoHS 3 directives and is free from intentionally added lead. Ensure procurement channels are authorized to guarantee compliance with standard terms and conditions.

Selection Notes

Select this component when a matched pair of Zener diodes is required in a minimal footprint. The common anode topology simplifies biasing compared to separate discrete components. Consider the 300 mW power rating and thermal resistance for heat dissipation requirements in dense PCB layouts.

Part Context

This part belongs to the AZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all sharing the same SOT-23 mechanical outline and electrical testing parameters. The 'AZ23C' prefix identifies the specific product family within the manufacturer's portfolio.

Replacement Considerations

For automotive applications requiring specific change control and IATF 16949 manufacturing, consider the Q-suffix variant (e.g., AZ23C6V2Q-7-F). For common cathode configurations, review the DZ23 series. Direct pin-compatible replacements must match the 6.2 V nominal voltage and 300 mW power dissipation limits.

FAQ
