DZ23C6V8-7

Overview

The DZ23C6V8-7 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 diodes within a single case. The nominal Zener voltage is 6.8 V with a tolerance of ±5%, ranging from 6.4 V to 7.2 V. Maximum power dissipation is 300 mW at 25°C ambient temperature, supported by a thermal resistance (junction to ambient) of 417 °C/W. The maximum Zener impedance (ZZT) at a test current of 5.0 mA is 8.0 Ω, while the impedance at low current (ZZK, 1.0 mA) is 150 Ω. The device 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.

• Biasing networks in analog electronic systems.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging and qualification status. The standard commercial variant utilizes a tape and reel shipping format. Confirm compliance requirements such as RoHS and halogen-free status align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution in a common cathode topology is required within a compact SOT-23 footprint. Ensure the 6.8 V nominal voltage and 300 mW power dissipation limits suit the target application's electrical constraints. Consider the thermal resistance characteristics if operating near the upper temperature limits.
