1N5377CE3/TR8

Overview

The Microsemi Corporation 1N5377CE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333 to 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 91 V with a tight tolerance of ±2%. The device operates within an ambient temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 75 Ohms, a test current of 15 mA, and a maximum reverse current of 0.5 µA.

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 changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required

Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply reference designs
• Protection against overvoltage conditions in electronic systems

Procurement Notes

Verify that the component matches the specific part number 1N5377CE3/TR8 to ensure correct voltage rating and tolerance. Confirm RoHS compliance status via the e3 suffix and check for any military screening prefixes if applicable. Ensure the supplier documentation references the official Microsemi datasheet for accurate electrical parameters and mechanical dimensions before finalizing procurement.

Selection Notes

Select this component when a 91 V Zener voltage with ±2% tolerance is required for high-power applications up to 5 watts. Consider the T-18 axial package for through-hole mounting and verify thermal management requirements based on the specified junction-to-lead thermal resistance. Ensure the operating environment falls within the -65°C to +150°C temperature range.
