1N5377BE3/TR13

Overview

The Microsemi Corporation 1N5377BE3/TR13 is a silicon Zener diode with a nominal voltage of 91 V and a ±5% tolerance. It operates in the T-18 axial package, dissipating up to 5 W at 25 °C. Key electrical parameters include a test current of 15 mA, maximum dynamic impedance of 75 Ω, and reverse leakage current of 500 µA at 65.5 V. The device withstands a surge current of 760 A and functions within a temperature range of -65 °C to +150 °C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for versatile integration

Applications

• Voltage regulation circuits requiring robust thermal performance
• High-density electronic assemblies utilizing tape-and-reel packaging
• Power supply protection against transient overvoltage events

Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm the presence of the 'e3' designation indicates RoHS compliance and matte-tin plating. Ensure the 'TR' suffix corresponds to the tape-and-reel packaging format rather than bulk or other container types before finalizing procurement orders.

Selection Notes

Select this component when a 91 V Zener reference is needed with a ±5% tolerance. Consider the T-18 package dimensions and lead length requirements for adequate heat sinking. Evaluate the 75 Ω dynamic impedance against circuit sensitivity requirements to ensure proper noise and regulation performance.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The B suffix specifically denotes a standard ±5% voltage tolerance, distinguishing it from tighter tolerance variants like C or D suffixes.

Replacement Considerations

Surface mount equivalents are available as SMBG5377B or SMBJ5377B.
