1N5371C/TR12

Overview

The Microchip Technology 1N5371C/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 60 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse leakage current of 0.5 µA at 43 V and a dynamic impedance of 40 Ω at a test current of 20 mA. The component 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 circuits requiring high power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the specific suffix configuration to ensure compliance with required tolerance levels and packaging formats. Confirm RoHS status and lead material specifications against project requirements. Validate thermal management needs based on the junction-to-lead thermal resistance characteristics provided in the datasheet.

Selection Notes

Select this component for applications demanding precise voltage regulation with tight tolerances. Ensure adequate heat sinking is implemented to maintain operation within the specified power dissipation limits. Consider the axial lead form factor when designing PCB layouts for mechanical stability.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The C suffix specifically denotes a tighter ±2% voltage tolerance compared to standard B or A suffix variants.

Replacement Considerations

Equivalent parts include 1N5371B for standard tolerance or 1N5371D for tighter 1% tolerance. Surface mount alternatives are available as SMBJ5371 or SMBG5371.
