1N5371AE3/TR8

Overview

The Microchip Technology 1N5371AE3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 60V and ±10% tolerance. It operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 40 ohms at a test current of 20mA. The device includes RoHS-compliant tin plating (e3 suffix) and is supplied in tape and reel packaging (TR8 suffix).

Feature Summary

• Provides voltage regulation across a broad operating current and temperature range.
• Withstands high surge stresses and offers minimal voltage change versus current.
• Features flexible axial-lead mounting terminals for standard PCB integration.

Applications

• Voltage regulation circuits requiring 5W power dissipation.
• Protection against overvoltage conditions in electronic systems.
• Reference voltage sources in power supply designs.

Procurement Notes

Verify the specific suffixes match requirements: 'A' indicates ±10% tolerance, 'e3' confirms RoHS compliance, and 'TR8' denotes tape and reel packaging. Confirm the manufacturer source is Microsemi/Microchip Scottsdale Division. Ensure the component meets JEDEC registration standards for the 1N53xx series before procurement.

Selection Notes

Select this component when a 60V Zener voltage with ±10% tolerance is required. Consider the 5W power rating and thermal resistance characteristics for heat sinking needs. Verify that the axial lead package fits the mechanical constraints and that the tape and reel format aligns with automated assembly processes.

Part Context

This part belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers voltages from 3.3V to 200V with various tolerance options. The 1N5371 variant specifically targets the 60V application segment within this high-power axial-leaded family.

Replacement Considerations

Direct substitutes include other 1N5371 variants with different tolerances (e.g., 1N5371B for ±5%) or packaging. Surface mount equivalents such as SMBJ5371 are available for space-constrained designs. Verify thermal and electrical parameters match when cross-referencing with generic 5W Zener diodes.

FAQ
