DZ23C2V7-7

Overview

The DZ23C2V7-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It integrates two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 2.7 V, with an operating range of 2.5 V to 2.9 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 83 Ω at 1 kHz and 500 Ω at low current. The device supports a maximum power dissipation of 300 mW and operates across 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 compliant with JEDEC standards for demanding applications.
• Environmentally compliant construction featuring lead-free, halogen-free, and antimony-free materials.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Clamping and protection stages in signal processing paths.
• Automotive electronics utilizing automotive-grade component alternatives.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the commercial grade variant matches the intended application requirements. Ensure compatibility with automated insertion processes by validating the tape and reel packaging specifications. Cross-reference the date code marking to confirm manufacturing origin and assembly site details.

Selection Notes

Select this component when a compact dual Zener solution is required in an SOT-23 footprint. Evaluate the thermal resistance of 417 °C/W to ensure adequate heat dissipation on the FR4 PCB layout. Consider the negative temperature coefficient for low-voltage stability requirements. Verify that the reverse leakage current characteristics meet the specific circuit isolation needs.

Part Context

This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes. The series covers a wide voltage range from 2.7 V to 51 V. Variants are available in both common cathode (DZ23C) and common anode (AZ23C) configurations. Automotive qualified versions utilize a Q-suffix designation for IATF 16949 certified manufacturing.

Replacement Considerations

The AZ23C2V7-7-F serves as a functional replacement offering a common anode configuration instead of common cathode. For automotive applications, verify availability of the corresponding Q-suffix part number. Direct pin-compatible substitutes must maintain identical SOT-23 mechanical dimensions and electrical thresholds.
