DZ23C9V1-7-F

Overview

The DZ23C9V1-7-F is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 9.1 V and a tolerance range of 8.5 V to 9.6 V at a test current of 5.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance (ZZT) of 10 Ω and a typical temperature coefficient of +0.065 %/°C.

Feature Summary

• Dual Zener diodes integrated into a single common cathode configuration for space-efficient circuit design.
• High reliability qualification compliant with JEDEC standards for demanding applications.
• Environmentally compliant construction that is fully lead-free, halogen-free, and antimony-free.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Over-voltage protection stages in signal conditioning paths.
• Clamping networks for transient suppression in sensitive electronics.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm commercial versus automotive grade status. Ensure the requested quantity aligns with standard shipping configurations such as tape and reel formats. Cross-reference the component marking codes to validate authenticity upon receipt.

Selection Notes

Select this component when a precise 9.1 V breakdown voltage is required in a compact footprint. Evaluate the thermal resistance and derating curves if operating near the maximum junction temperature limit. Confirm that the positive temperature coefficient aligns with the stability requirements of the target application environment.

Part Context

This part belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all sharing identical mechanical dimensions and packaging standards. The product line is designed to facilitate automated insertion processes while maintaining consistent electrical performance across the voltage spectrum.

Replacement Considerations

Direct substitutes within the same family include DZ23C8V2-7-F and DZ23C10-7-F. Verify pinout compatibility and ensure the alternative voltage rating meets the circuit's operational thresholds before implementation.

FAQ

What is the polarity configuration of the internal diodes?

The device utilizes a common cathode configuration where the cathodes of both Zener diodes are connected to a single terminal.

How does the Zener voltage change with temperature?

The component exhibits a positive temperature coefficient of approximately +0.065 %/°C, meaning the breakdown voltage increases slightly as temperature rises.

Is this component suitable for high-reliability environments?

Yes, the device is qualified to JEDEC standards for high reliability, though automotive-specific variants require the Q-suffix designation.
