1N5334CE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5334CE3/TR8 is a JEDEC registered silicon 5.0-watt Zener diode in the 1N5333-5388B series, housed in an axial-leaded T-18 plastic package with a TR suffix for tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 3.6 V with a tight ±2% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 2.5 ohms at a test current of 350 mA. It includes RoHS compliance indicated by the e3 suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify that the component matches the specific C suffix for ±2% tolerance and the e3 suffix for lead-free RoHS compliance. Confirm the TR suffix indicates tape and reel packaging rather than bulk or cut tape. Ensure the manufacturer designation aligns with Microsemi specifications for this JEDEC registered series.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference with tight ±2% accuracy is required. Consider the 5 W power dissipation capability and thermal resistance characteristics for heat sinking requirements. Verify compatibility with the T-18 axial lead form factor and ensure the operating environment falls within the specified -65°C to +150°C range.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments with low thermal resistance.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5 W Zener diodes with 3.6 V nominal voltage and ±2% tolerance in a T-18 package. Verify electrical parameters such as dynamic impedance and test current match the original design requirements before substitution.
