1N5377CE3/TR13

Overview

The Microsemi Corporation 1N5377CE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333B-1N5388B series, housed in an axial T-18 package with a TR suffix for tape and reel packaging. It provides a nominal Zener voltage of 91 V with a tight ±2% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 75 Ohms at a test current of 15 mA. It includes RoHS compliance via the e3 suffix.

Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance using the C suffix designation.
• Engineered for high surge stress withstand capabilities and minimal voltage change versus current.
• Features flexible axial-lead mounting terminals suitable for through-hole applications.
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density circuit protection requiring robust thermal performance
• Power supply reference circuits utilizing axial lead mounting

Procurement Notes

Verify that the specific part number matches the required electrical characteristics, particularly the 91 V nominal voltage and ±2% tolerance indicated by the 'C' suffix. Confirm the 'TR' suffix aligns with the necessary tape and reel packaging format for automated assembly processes. Ensure the 'e3' suffix confirms RoHS compliance if environmental regulations apply to the manufacturing environment.

Selection Notes

Select this component when a 5-watt power dissipation rating is required alongside a 91 V regulation point. The T-18 axial package offers lower thermal resistance compared to glass-body options, supporting higher DC currents with adequate heat sinking. Consider the ±2% tolerance for applications demanding tighter voltage accuracy than standard B or A suffix devices provide.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 to 200 volts. The 1N5377 variant specifically targets the 91-volt regulation segment within this extensive lineup of plastic encapsulated, moisture classification Level 1 devices.

Replacement Considerations

Surface mount equivalents are available as SMBJ5377 or SMBG5377A. These variants offer identical electrical characteristics and testing while providing gull-wing designs for low-profile mounting on FR4 PC boards.
