1N5312 TR PBFREE

Overview

The 1N5312 TR PBFREE is a silicon planar Zener diode manufactured by Central Semiconductor Corp. It provides a nominal Zener voltage of 47 V with a power dissipation rating of 5 W. The device utilizes a DO-201AE axial leaded package and is supplied in tape and reel format. Key electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a test current of 21 mA. The component supports an operating junction temperature range from -65°C to +175°C, ensuring reliability across wide thermal conditions.

Feature Summary

• High power dissipation capability for robust voltage regulation
• Wide operating junction temperature range for extreme environments
• Low noise performance suitable for sensitive circuits
• Axial leaded construction for through-hole mounting

Applications

• High-power voltage reference sources
• Overvoltage protection circuits
• Power supply regulation stages

Procurement Notes

Verify the specific manufacturer datasheet for the 1N5312 TR PBFREE to confirm exact tolerance grades and testing conditions. Ensure the procurement channel provides authentic Central Semiconductor products with appropriate RoHS compliance documentation. Confirm that the tape and reel packaging matches the required quantity increments for automated assembly processes.

Selection Notes

Select this component when a 47 V Zener voltage with 5 W power handling is required in an axial package. Consider the 5 µA leakage current specification for applications demanding minimal standby drain. Verify that the circuit design accommodates the thermal requirements associated with 5 W dissipation in the DO-201AE housing.

Part Context

This part belongs to the standard 1N53xx series of high-power Zener diodes produced by Central Semiconductor. The 'TR' suffix indicates tape and reel packaging, while 'PBFREE' denotes lead-free composition. This series is designed for general-purpose voltage regulation tasks requiring higher power handling than standard small-signal diodes.

Replacement Considerations

Cross-reference with other manufacturers offering 47 V, 5 W Zener diodes in the DO-201AE package. Verify pinout compatibility and thermal resistance values before substitution. Ensure alternative parts meet the same -65°C to +175°C operating temperature range.
