DZ23B24-G3-08

Overview

The DZ23B24-G3-08 is a Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual-diode configuration with a common cathode arrangement housed in an SOT-23-3 surface-mount package. The nominal Zener voltage is specified at 24 V with a tolerance of ±5%. The device supports a maximum power dissipation of 300 mW and exhibits a maximum Zener impedance (Zzt) of 10 Ohms. Reverse leakage current is limited to 1 µA when tested at 18 V. The component operates within a junction temperature range of -55°C to +150°C and complies with RoHS directives.

Feature Summary

• Dual Zener diode structure integrated into a single compact surface-mount package
• Common cathode configuration simplifies circuit layout for voltage reference applications
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• Voltage regulation in portable electronic devices
• Clamping circuits for signal protection
• Reference voltage generation in measurement equipment

Procurement Notes

Verify the specific suffix G3 against manufacturer documentation to confirm lead-free compliance status, as suffixes define material composition. Confirm availability through authorized distributors, noting that standard packaging quantities may vary. Ensure the ordering part number matches the exact electrical specifications required for the design to avoid substitution errors during procurement.

Selection Notes

Select this component when a dual Zener solution with common cathode topology is required in a small footprint. The 300 mW power rating suits low-current regulation tasks. Verify that the 24 V nominal voltage aligns with system requirements and that the SOT-23-3 package fits the PCB layout constraints. Consider the 10 Ohm impedance for precision needs.

Part Context

This part belongs to the DZ23 series of Zener diode arrays from Vishay. The series offers various voltage options in the SOT-23-3 package, providing designers with flexible dual-diode solutions. The DZ23B24 variant specifically targets applications requiring a 24 V reference or clamping level in space-constrained designs.

Replacement Considerations

Check for direct equivalents from Vishay such as DZ23B24-E3-08. Other manufacturers offering SOT-23-3 dual Zener arrays with 24 V common cathode configurations may serve as functional substitutes if electrical parameters match.
