Single Zener Diodes Overview

The Central Semiconductor Corp 1N5343B BK is a high-power Zener diode designed for surface-mount applications. It utilizes the SMC package and offers a nominal Zener voltage of 7.5 V with a 5% tolerance. The device supports a maximum power dissipation of 10 W at specified conditions, operating reliably within a temperature range from -65°C to +175°C. Key electrical characteristics include a test current of 175 mA, a maximum reverse leakage current of 100 µA, and a Zener impedance of 1.5 Ohms.

Single Zener Diodes Feature Summary

High power handling capability suitable for demanding circuit protection tasks
Surface-mount construction for automated assembly integration
Wide thermal operating range ensuring stability in extreme environments

Single Zener Diodes Applications

Voltage regulation in high-power industrial equipment
Over-voltage protection circuits
Reference voltage sources in precision instrumentation

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements when ordering, as plating options such as Tin/Lead or Lead-Free must be explicitly requested by adding the corresponding suffix to the part number. Confirm that the SMC package dimensions align with your PCB footprint design. Ensure that the 10 W power rating is supported by adequate thermal management on the target board layout.

Single Zener Diodes Selection Notes

Select this component when a robust surface-mount solution is required for 7.5 V regulation. Compare the 10 W dissipation against available board space and cooling methods. Verify that the 1.5 Ohm impedance meets the noise sensitivity requirements of the application. Consider the wide temperature range if the environment exceeds standard commercial limits.

Single Zener Diodes Part Context

This device belongs to the high-power Zener diode family from Central Semiconductor. It serves as a surface-mount alternative to traditional axial-lead packages like DO-201AA. The SMC form factor allows for higher density mounting compared to through-hole equivalents while maintaining significant power handling capabilities for critical voltage reference applications.
