1N5371CE3/TR8

Overview

The Microchip Technology 1N5371CE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at 60V with a tight ±2% tolerance, indicated by the C suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 40 Ohms and a maximum reverse current of 0.5 µA. It is RoHS compliant (e3 suffix) and available in tape and reel packaging (TR8 suffix).

Feature Summary

• Provides precise voltage regulation with ±2% tolerance for sensitive circuit applications.
• Capable of handling high surge stresses and operating at high DC currents with adequate heat sinking.
• Features flexible axial-lead mounting terminals suitable for through-hole assembly.
• Resistant to electrostatic discharge (ESD) per MIL-STD-750 Method 1020.

Applications

• Voltage regulation in power supply circuits requiring stable reference voltages.
• Protection against voltage spikes and transient overvoltage events.
• Clamping applications in electronic systems exposed to high surge stresses.

Procurement Notes

Verify the specific suffixes on the part number to confirm tolerance and packaging options. The 'C' suffix indicates a ±2% voltage tolerance, while 'e3' confirms RoHS compliance. The 'TR8' suffix denotes tape and reel packaging. Ensure that the procurement documentation matches these identifiers to avoid receiving variants with different tolerances or packaging formats.

Selection Notes

Select this component when a 60V Zener diode with tight ±2% tolerance is required for precision regulation. Consider the 5W power dissipation rating and thermal resistance of 25°C/W junction-to-lead when designing heat sinking solutions. Verify that the operating environment stays within the specified -65°C to +150°C temperature range for reliable performance.

Part Context

This component belongs to the Microsemi (now Microchip Technology) Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options. These devices are designed for robust operation in demanding environments, featuring void-free transfer molded epoxy bodies meeting UL94V-0 standards.

Replacement Considerations

Compatible substitutes within the same series include other 1N53xxB/C parts with matching voltage ratings. For equivalent specifications, verify that replacement parts maintain the 5W power dissipation, T-18 package, and ±2% tolerance requirements. Cross-reference datasheets to ensure thermal and electrical characteristics align with the original design constraints.
