1N5377AE3/TR13

Overview

The Microsemi Corporation 1N5377AE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial T-18 package with a TR suffix for tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 91V with a ±10% tolerance indicated by the A suffix. 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 stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for high-density applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring robust thermal performance
• High-density mounting environments utilizing axial lead components
• Applications demanding high specified maximum current with adequate heat sinking

Procurement Notes

Verify that the part number matches the specific electrical characteristics required, particularly the 91V Zener voltage and ±10% tolerance associated with the 'A' suffix. Confirm the presence of the 'e3' suffix for RoHS compliance and the 'TR' suffix for tape and reel packaging format. Ensure compatibility with the T-18 axial lead package dimensions for your printed circuit board layout.

Selection Notes

Select this component when a 5-watt power dissipation rating is necessary for voltage regulation tasks. The axial lead configuration offers mechanical stability compared to surface mount alternatives. Consider the wide operating temperature range and low thermal resistance design if the application involves high DC currents or requires operation under varying ambient conditions without excessive heat sinking.

Part Context

This component belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a voltage selection from 3.3 to 200 volts with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for applications requiring reliable voltage regulation and high surge current handling capabilities.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. For military screening requirements, prefixes such as MQ, MX, or MV can be added to access JAN, JANTX, or JANTXV versions respectively.
