1N5286 TR PBFREE

Overview

The Central Semiconductor Corp 1N5286 TR PBFREE is a silicon planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 75 V with a tolerance of ±5%. The device operates within a power dissipation rating of 500 mW and supports a maximum reverse leakage current of 5 µA at the rated voltage. Packaged in the DO-35 axial leaded format, it is supplied in tape and reel configurations to facilitate automated surface mounting processes.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation performance
• Provides precise voltage control with ±5% tolerance specification
• Engineered for low noise operation suitable for sensitive circuits

Applications

• Voltage reference sources in precision measurement equipment
• Overvoltage protection stages in signal conditioning paths
• Bias stabilization networks in analog amplifier circuits

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact electrical tolerances and testing criteria. Ensure that the procurement channel provides valid RoHS compliance certificates matching the PBFREE designation. Confirm that the delivered tape and reel packaging meets the required moisture sensitivity level standards for your assembly line.

Selection Notes

Select this component when a 75 V regulation point is required in an axial package environment. Evaluate the 500 mW thermal limit against the expected operating current to ensure adequate heat dissipation. Compare the 5 µA leakage specification against circuit requirements to determine if lower leakage alternatives are necessary for high-impedance nodes.

Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by Central Semiconductor. The series offers a wide range of voltage values from low voltages up to high voltage thresholds. The TR PBFREE suffix indicates a lead-free, tape-and-reel packaged version of the traditional through-hole component, bridging legacy form factors with modern automation needs.

Replacement Considerations

Cross-reference with other manufacturers offering 1N5286 equivalents in DO-35 packages. Verify that substitute parts maintain the same 75 V nominal voltage and 500 mW power rating. Check for any differences in dynamic impedance or temperature coefficients that might affect circuit stability.
