1N5293 TR PBFREE

Overview

The 1N5293 TR PBFREE is a single Zener diode manufactured by Central Semiconductor Corp, designed for surface-mount applications in the SMA-2 package. It features a nominal Zener voltage of 68 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device exhibits a maximum reverse leakage current of 5 µA at 50 V and a Zener impedance of 40 Ohms at a test current of 3.7 mA. It operates within a junction temperature range of -65°C to +150°C and complies with RoHS standards.

Feature Summary

• Provides stable voltage regulation through precise Zener breakdown characteristics in a compact surface-mount form factor.
• Engineered for low leakage current operation to minimize standby power consumption in sensitive circuits.
• Capable of reliable performance across extended industrial temperature ranges suitable for harsh environments.

Applications

• Voltage reference sources in precision measurement instrumentation
• Overvoltage protection stages in signal conditioning circuits
• Biasing networks for transistor amplifiers

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Central Semiconductor documentation. Confirm that the ordering suffix corresponds to the specified tape and reel packaging format. Ensure compliance with relevant environmental directives before integration into final assemblies.

Selection Notes

Select this component when a 68 V reference is required in a surface-mount design. Evaluate the 500 mW power rating against expected thermal conditions. Compare the 40 Ohm impedance specification with circuit sensitivity requirements to ensure adequate regulation stability under varying load currents.

Part Context

This part belongs to the standard 1N52xx series of Zener diodes produced by Central Semiconductor. The series offers various voltage options in both through-hole and surface-mount packages. The TR suffix indicates tape and reel packaging for automated assembly processes.

Replacement Considerations

Consult manufacturer substitution guides for parameter-equivalent alternatives. Verify pin compatibility and thermal characteristics when considering cross-brand replacements.
