Overview
The Microsemi Corporation 1N5377E3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 91 V with a ±20% tolerance. The device features a T-18 axial lead package and supports a maximum power dissipation of 5 watts. Electrical characteristics include a maximum dynamic impedance of 75 Ohms, a reverse leakage current of 500 nA at 65.5 V, and a forward voltage of 1.2 V at 1 A. It operates 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 changes in voltage versus current
- Features flexible axial-lead mounting terminals for standard through-hole integration
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation in power supply circuits
- Protection against transient overvoltage events
- Reference voltage generation in electronic systems
Procurement Notes
Verify that the part number suffix 'e3' confirms RoHS compliance and 'TR13' indicates tape and reel packaging. Confirm the manufacturer is Microsemi Corporation or its successor entity. Ensure the component matches the T-18 axial lead physical dimensions and electrical specifications provided in the official datasheet before procurement.
Selection Notes
Select this component when a 91 V Zener voltage with ±20% tolerance is required. The 5-watt power rating necessitates adequate heat sinking or specific PCB copper pad layouts to maintain thermal limits. Verify that the T-18 axial package fits the design constraints compared to surface mount equivalents like SMBG5377A.
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 offers a wide selection of voltages from 3.3 V to 200 V. The 'e3' suffix denotes RoHS compliant matte-tin plating, while the 'TR' suffix indicates availability in tape and reel packaging for automated assembly.
Replacement Considerations
Surface mount equivalents such as SMBG5377A are available with identical electrical characteristics. Other voltage variants within the 1N5333B-1N5388B series may be considered if different regulation voltages are needed.
