1N5371/TR8

Overview

The Microchip Technology 1N5371/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 60V. It features a ±5% tolerance and operates within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes a TR suffix for tape and reel packaging. Electrical characteristics include a maximum dynamic impedance of 40 ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 45.5 mA.

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

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific manufacturer origin as datasheet references may indicate Microsemi Scottsdale Division. Confirm RoHS compliance status by checking for the e3 suffix, as standard versions may not meet current environmental standards. Ensure the TR suffix matches required automated assembly equipment specifications before finalizing procurement orders.

Selection Notes

Select this component when a 60V regulation point is required at up to 5 watts of power dissipation. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify that the 40-ohm dynamic impedance meets circuit sensitivity needs compared to lower-voltage alternatives which typically offer tighter impedance values.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. The 1N5371 variant specifically addresses the 60V segment of this high-power regulatory lineup.

Replacement Considerations

Equivalent parts within the same series include 1N5370B (56V) and 1N5372B (62V). Cross-manufacturer equivalents should be verified against the 5W power rating and T-18 package dimensions.
