DZ23C12-7-F

Overview

The DZ23C12-7-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 junctions within a single case. The nominal Zener voltage is 12V, operating within a range of 11.4V to 12.7V at a test current (IZT) of 5.0mA. Maximum Zener impedance is specified as 20 Ohms at IZT and 90 Ohms at IZK of 1.0mA. The device supports a maximum power dissipation of 300mW and operates across 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 suitable for demanding applications.
• Environmentally compliant construction that is fully lead-free, halogen-free, and antimony-free.

Applications

• Voltage reference circuits requiring stable dual voltage rails.
• Clamping and protection stages in signal processing paths.
• Automotive electronics systems utilizing commercial grade components.

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging and qualification status. The standard commercial variant utilizes tape and reel packaging with a shipping quantity of 3000 units per reel. Confirm compliance requirements such as RoHS and REACH directives match project specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact dual Zener solution is required in an SOT-23 footprint. Ensure the application current does not exceed the 5.0mA test current threshold to maintain accurate voltage regulation. Consider the thermal resistance of 417 °C/W and apply appropriate derating curves if ambient temperatures approach the upper operational limit of 150°C.

Part Context

This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7V to 51V, all sharing identical mechanical dimensions and electrical characteristics profiles. The product line is designed for automated insertion processes and offers consistent performance across the entire voltage range.

Replacement Considerations

Direct substitutes include other DZ23C series variants with matching voltage ratings or the AZ23 series for common anode configurations. Cross-manufacturer equivalents must be verified against the SOT-23 pinout and maximum power dissipation limits to ensure functional compatibility without redesigning the host circuit board.
