DZ23C27-7

Overview

The DZ23C27-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 27 V with a tolerance range of 25.1 V to 28.9 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance (ZZT) is 80 Ω at 1 kHz. The typical temperature coefficient is +0.090 %/°C, and the minimum reverse voltage is 20.0 V. The device operates within a temperature range of -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common cathode configuration for space-efficient circuit design.
• High reliability qualification meeting JEDEC standards for robust performance in demanding environments.
• Environmentally compliant construction that is totally lead-free, fully RoHS compliant, and halogen and antimony free.

Applications

• Voltage reference circuits requiring stable dual voltage rails.
• Over-voltage protection stages in signal conditioning paths.
• Clamping applications for transient suppression in low-power electronics.

Procurement Notes

Verify the specific ordering suffix when sourcing components. The standard commercial version utilizes the -7-F suffix, while automotive-grade variants require the Q-7-F suffix. Confirm that the procurement channel provides original manufacturer documentation to ensure compliance with the specified electrical characteristics and environmental standards.

Selection Notes

Select this component based on the required nominal voltage of 27 V and the 300 mW power dissipation limit. Ensure the application environment stays within the -65 °C to +150 °C operating range. Consider the 80 Ω maximum impedance for dynamic regulation requirements and verify that the SOT-23 footprint matches the PCB layout constraints.

Part Context

This part belongs to the DZ23C series of dual surface mount Zener diodes from Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, all sharing the same compact SOT-23 package and 300 mW power rating. This family is designed for automated insertion and offers matched voltage tracking between the two internal diodes.

Replacement Considerations

Direct replacements within the same series include DZ23C24-7-F and DZ23C30-7-F if voltage adjustments are permissible. For automotive applications, the corresponding qualified parts are DZ23C24Q-7-F or DZ23C30Q-7-F. Verify pinout compatibility and thermal resistance specifications before substitution.
