1N5335C/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5335C/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 3.9 V and a tight tolerance of ±2%. It features an axial-lead T-18 plastic package and operates within a temperature range of -65°C to +150°C. The device exhibits a maximum dynamic impedance of 2.0 ohms at a test current of 320 mA, with a maximum reverse leakage current of 50 µA tested at 1.0 V. It includes a tape and reel packaging option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with ±2% tolerance for high-accuracy applications
• Capable of handling high surge stresses and steady-state power dissipation up to 5 watts
• Features flexible axial-lead mounting terminals suitable for through-hole integration
• Moisture classification Level 1 eliminates the requirement for dry pack storage

Single Zener Diodes Applications

• Precision voltage reference circuits requiring stable low-voltage regulation
• Power supply output regulation and overvoltage protection stages
• High-reliability electronic systems utilizing military equivalent screening levels

Single Zener Diodes Procurement Notes

Verify that the component matches the specific C suffix designation for ±2% tolerance rather than standard B or A variants. Confirm the presence of the TR suffix indicates tape and reel packaging. Ensure the part number corresponds to the JEDEC registered series documentation provided by Microsemi for accurate electrical parameter validation.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required alongside robust thermal performance. The 5-watt power rating allows operation at high DC currents with adequate heat sinking. Consider the T-18 axial lead form factor for mechanical stability in environments subject to vibration or high surge currents.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zener diodes. The series provides a wide selection of voltages from 3.3 to 200 volts. The C suffix specifically identifies the tighter ±2% tolerance variant within this family of plastic encapsulated components.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 3.9 V 5 W Zener diodes with ±2% tolerance in T-18 packages. Verify compatibility regarding thermal resistance characteristics and maximum surge current ratings before substitution.
