BZB84-C43,215

Overview

The BZB84-C43,215 is a dual common anode Zener diode manufactured by Nexperia. It features a nominal Zener voltage of 43 V with a tolerance of 5%. The device operates within a temperature range of -55 °C to +150 °C and has a maximum power dissipation of 300 mW. Key electrical parameters include a maximum reverse leakage current of 50 nA, a Zener impedance of 255 Ohms, and a test current of 2 mA. The component is housed in a TO-236AB (SOT23) surface-mount package with dimensions of 2.9 mm length, 1.3 mm width, and 1 mm height.

Feature Summary

• Dual common anode configuration for efficient space utilization
• High thermal stability supporting extended operating temperatures
• Low leakage current characteristics for precision applications

Applications

• Voltage reference circuits requiring stable dual references
• Overvoltage protection in low-power electronic systems
• Signal clamping in communication interfaces

Procurement Notes

Verify the manufacturer designation as Nexperia when sourcing this part, as NXP USA Inc. may list it under its subsidiary brand. Confirm the specific suffix ,215 corresponds to the required tape and reel packaging format. Ensure compatibility with the TO-236AB footprint during procurement planning.

Selection Notes

Select this component when a dual Zener solution is required in a compact SOT23 package. The 43 V rating suits applications needing moderate voltage regulation. Consider the 300 mW power limit and thermal constraints for PCB layout. Verify that the 5% tolerance meets the circuit's precision requirements.

Part Context

This component belongs to the BZB84 series of dual Zener diodes from Nexperia. It shares the same physical package and general specifications as other variants in the series, differing primarily in the specific Zener voltage ratings. The series is designed for general-purpose voltage regulation and protection tasks.

Replacement Considerations

Compatible substitutes include other BZB84 series parts with similar voltage ratings or alternative dual Zener diodes in SOT23 packages. Verify pinout compatibility and ensure equivalent electrical parameters such as power dissipation and leakage current before substitution.
