1N5371A/TR12

Overview

The Microchip Technology 1N5371A/TR12 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, featuring a maximum reverse current of 0.5µA at 43V and a dynamic impedance of 40Ω. The device utilizes an axial-lead T-18-2 package and is supplied in tape-and-reel format.

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 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 suffix 'TR12' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component for applications requiring robust 5-watt power dissipation and high thermal stability. Consider the ±10% voltage tolerance and 40Ω dynamic impedance when designing precision regulation circuits. Evaluate the T-18-2 package dimensions for adequate heat sinking and PCB layout constraints.

Part Context

This component belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip). The series offers a wide selection of voltages from 3.3V to 200V in a standard axial-lead package designed for high-power regulation applications.

Replacement Considerations

Equivalent parts include the 1N5371B (±5% tolerance) or 1N5371C (±2% tolerance). Verify that substitute components match the 5W power rating and T-18 package footprint.
