DZ23C13-7-F

Overview

The DZ23C13-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage ranges from 12.4 V to 14.1 V at a test current of 5.0 mA. Maximum Zener impedance is 25 Ω at IZT = 5.0 mA and 110 Ω at IZK = 1.0 mA. The device has a power dissipation rating of 300 mW, a thermal resistance (junction to ambient) of 417 °C/W, and 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 designs.
• Low profile SOT-23 package suitable for automated insertion and high-density PCB layouts.
• Voltage matching between the two diodes in one case is maintained within a 5% tolerance.
• Fully RoHS compliant and halogen-free construction.

Applications

• Voltage reference circuits requiring dual stable voltage rails.
• Clamping and protection stages in signal processing paths.
• Biasing networks in transistor amplifier stages.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm commercial qualification and tape-and-reel packaging quantities. Ensure that the selected component meets the required environmental standards and lead-free specifications for the intended assembly process.

Selection Notes

Select this component when a dual Zener solution with matched voltage characteristics is required in a compact footprint. Consider the maximum Zener impedance and reverse leakage current limits relative to the circuit's sensitivity. Verify that the 300 mW power dissipation rating accommodates the expected operating conditions without exceeding thermal limits.

Part Context

This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same SOT-23 mechanical outline and common cathode topology. The '-7-F' suffix indicates commercial grade qualification and standard reel packaging.

Replacement Considerations

Direct replacements include other DZ23C13 variants such as DZ23C13-7 or DZ23C13Q-7-F for automotive applications. Cross-brand equivalents must match the SOT-23 package, 12.4-14.1 V Zener range, and 300 mW power rating.
