1N5342/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5342/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 6.8 V with a ±5% tolerance. The device operates in a T-18 axial lead package and supports a maximum reverse current test voltage of 3.0 V. Electrical characteristics include a test current of 175 mA, a maximum dynamic impedance of 1.0 ohm, and a maximum reverse leakage current of 10 µA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for standard through-hole integration

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High current applications with adequate heat sinking
• General purpose electronic equipment protection

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required tolerance levels and RoHS compliance standards. Confirm that the TR8 tape and reel packaging aligns with automated assembly requirements. Cross-reference the manufacturer's datasheet for derating curves and thermal resistance specifications to validate suitability for the intended operating environment.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V reference point is required within a 5-watt power envelope. Ensure the application design accounts for the specified thermal resistance of 25 °C/W junction-to-lead. Verify that the circuit can handle the maximum regulator current of 700 mA under appropriate heat sinking conditions to maintain reliable operation.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage range from 3.3 V to 200 V. The 'TR' suffix indicates the device is supplied in tape and reel packaging, while the 'e3' designation typically denotes lead finish compliance, though specific suffix definitions should be verified against the official documentation.
