2BZX84C24

Overview

The Diotec Semiconductor 2BZX84C24 is a common anode SMD planar Zener diode housed in an SOT-23 package. It provides a nominal Zener voltage range of 22.8 V to 25.6 V at a test current (IZ) of 5 mA, with a dynamic resistance (rzj) of less than 80 ohms at 1 kHz. The device supports a total power dissipation of 300 mW and operates within a junction temperature range of -50°C to +150°C. Standard tolerance follows the E24 series (~±5%).

Feature Summary

• Common Anode configuration for dual-diode applications.
• Sharp Zener voltage breakdown characteristics.
• Low leakage current performance.
• RoHS compliant without exemptions.

Applications

• Voltage stabilization circuits.
• General-purpose voltage regulators.

Procurement Notes

Verify the specific suffix against official documentation to confirm grade. Absence of a suffix indicates industrial grade availability. Suffixes such as -Q or -AQ denote AEC-Q101 compliance or qualification respectively. Confirm that the commercial grade (-C) designation matches the intended application requirements before procurement.

Selection Notes

Select this component when a common anode topology is required for dual Zener regulation. Ensure the operating current remains below the maximum limit of 12 mA at 25°C ambient temperature. Verify thermal constraints on the PCB, as the 300 mW rating assumes mounting on pads with 3 mm² copper area per terminal.

Part Context

This part belongs to the BZX84Cxx and 2BZX84Cxx series from Diotec Semiconductor. It shares the SOT-23 footprint with single diode variants like the BZX84C24 but utilizes a common anode structure. The series covers Zener voltages from 2.4 V to 47 V with standard E24 tolerances.
