1N5342CE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5342CE3/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 6.2 volts and a ±2% tolerance, indicated by the 'C' suffix. It operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 package. The device has a maximum dynamic impedance of 1.0 ohm at a test current of 200 mA, with a maximum reverse leakage current of 10 µA tested at 3.0 volts. It is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight ±2% tolerance for sensitive circuit applications
• Capable of handling high surge stresses and steady-state power dissipation up to 5 watts
• Features low thermal resistance design allowing operation at high DC currents with adequate heat sinking

Single Zener Diodes Applications

• Voltage reference circuits requiring stable regulation over broad operating ranges
• Power supply protection against transient voltage spikes
• Overvoltage clamping in industrial electronic systems

Single Zener Diodes Procurement Notes

Verify the specific C suffix indicates the required ±2% tolerance level for your application. Confirm that the TR8 tape and reel packaging format matches your automated assembly equipment specifications. Ensure the component meets RoHS compliance requirements if mandated by your manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a 6.2-volt regulation point with high precision is necessary. The 5-watt power rating supports high-current applications provided sufficient thermal management is implemented. Consider the T-18 through-hole package constraints regarding board space and lead length requirements during layout.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide voltage selection from 3.3V to 200V with various tolerance options identified by suffix letters such as B, C, or D.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5342B for standard 5% tolerance or the 1N5342D for 1% tolerance. Surface mount alternatives are available in the SMBJ5342 or SMBG5342 families.
