DZ23C11-7

Overview

The DZ23C11-7-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 two independent Zener elements within a single case. The nominal Zener voltage ranges from 10.4 V to 11.6 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 20 Ω at IZT = 5.0 mA and 70 Ω at IZK = 1.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual Zener diodes integrated in a common cathode configuration for space-efficient circuit design.
• High reliability qualification meeting 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 when sourcing components. The standard commercial version utilizes the -7-F suffix, while automotive-grade variants require the Q-7-F designation. Confirm compliance with RoHS directives and ensure the selected part matches the required packaging format before finalizing procurement orders.

Selection Notes

Select this component based on the required Zener voltage tolerance and thermal management capabilities. Ensure the application circuit limits total power dissipation to 300 mW and accounts for the thermal resistance of 417 °C/W. Verify that the operating environment remains within the specified -65°C to +150°C junction temperature range for reliable performance.

Part Context

This component belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series provides various voltage options ranging from 2.7 V to 51 V, all sharing the same compact SOT-23 footprint and common cathode architecture to facilitate automated insertion and standardized PCB layouts.

Replacement Considerations

Direct replacements include other DZ23C series parts with matching voltage ratings or the AZ23 series for common anode configurations. Cross-manufacturer equivalents must be verified against the SOT-23 pinout and electrical characteristics to ensure functional compatibility without redesigning the host circuit.
