1N5359/TR8

Overview

The Microchip Technology 1N5359/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 24 volts with a standard ±5% tolerance. The device operates within a temperature range of -65°C to +150°C and features flexible axial-lead mounting terminals in a T-18 package. The TR8 suffix indicates tape and reel packaging compliant with EIA-296 standards.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
• Features flexible axial-lead mounting terminals for versatile installation

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High surge stress environments
• Applications necessitating ESD robustness

Procurement Notes

Verify the specific manufacturer origin, as the 1N5359 part number originates from the Microsemi Scottsdale Division acquisition by Microchip Technology. Confirm that the TR8 suffix correctly denotes the tape and reel packaging format. Ensure compliance requirements match the original datasheet specifications regarding moisture classification and lead plating options.

Selection Notes

Select this component when a 24-volt Zener reference with 5-watt capability is required. The ±5% tolerance suits general regulation needs. Consider the thermal resistance characteristics for heat sinking requirements. Verify that the axial-lead form factor fits the mechanical constraints of the target printed circuit board layout.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different suffix letters identify specific voltage tolerances, with the 'B' suffix designating the standard ±5% tolerance level found in this part.

Replacement Considerations

Compatible substitutes include other 5-watt Zener diodes with a 24V nominal voltage and ±5% tolerance. Verify equivalent power dissipation ratings and thermal resistance values. Ensure the replacement maintains the same axial-lead package dimensions and polarity markings.
