1N5371/TR12

Overview

The Microchip Technology 1N5371/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B-5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 60 V with a ±5% tolerance. The device operates in a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a test current of 20 mA, a maximum dynamic impedance of 40 Ohms, and a maximum reverse leakage current of 0.5 µA. The component is available in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits
• Surge protection systems
• Reference voltage generation

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and compliance status. Confirm availability as this part number may be subject to discontinuation or manufacturing changes. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the component.

Selection Notes

Select this component for applications requiring a 60 V reference with moderate precision. Consider the thermal resistance and power derating requirements when designing heat sinking solutions. Verify that the required surge current handling and dynamic impedance specifications align with the circuit design constraints.

Part Context

This component belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes originally produced by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. The product line includes RoHS-compliant variants and surface mount equivalents.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Surface mount equivalents such as SMBJ5371B are available within the same family.
