DZ23C3V0-7

Overview

The DZ23C3V0-7-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 is 3.0 V, operating within a range of 2.8 V to 3.2 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the device supports an operating temperature range from -65°C to +150°C. Key electrical parameters include a maximum Zener impedance (ZZT) of 95 Ω at 1 kHz and a typical temperature coefficient of -0.060 %/°C.

Feature Summary

• Dual Zener diodes integrated in a common cathode configuration for space-efficient circuit design.
• Ultra-small SOT-23 surface mount package suitable for automated insertion processes.
• Guaranteed voltage matching between both diodes within the same case, maintaining a delta VZ of less than or equal to 5%.

Applications

• Voltage reference circuits requiring precise low-voltage regulation.
• Clamping applications for protecting sensitive input lines.
• General-purpose voltage regulation in compact electronic devices.

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard commercial grade utilizes the -7-F suffix, while automotive-grade components qualified to AEC-Q101 standards require the Q-7-F suffix. Confirm that the required qualification level matches the intended application environment before placing orders.

Selection Notes

Select this component for designs requiring matched dual Zener voltages in a minimal footprint. Ensure the total power dissipation does not exceed 300 mW under worst-case thermal conditions. Verify that the negative temperature coefficient aligns with the thermal stability requirements of the target circuit.

Part Context

This part belongs to the DZ23C series, which covers Zener voltages ranging from 2.7 V to 51 V. All variants share identical mechanical dimensions and packaging specifications, differing only in their electrical characteristics such as breakdown voltage and impedance. The series provides a standardized solution for dual Zener needs across various voltage levels.

Replacement Considerations

Direct replacements must match the SOT-23-3 package and common cathode configuration. Check for equivalent Zener voltage ranges and power dissipation ratings. Automotive applications may require switching to the Q-suffix variant if AEC-Q101 qualification is mandatory.
