Overview
The Microsemi Corporation 1N5377E3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 91 V and ±20% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 760 µA at 69.2 V and a dynamic impedance of 75 Ω. The device utilizes an axial-lead T-18 package and includes a TR suffix for tape and reel packaging options.
Feature Summary
- Provides voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and offers minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals suitable for various heat sinking configurations
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection systems
- Reference voltage generation in electronic instrumentation
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and compliance status. Confirm availability as this component may be subject to discontinuation or lifecycle changes. Ensure the selected variant matches the required tolerance and thermal characteristics for the intended application environment.
Selection Notes
Select this component based on its 5-watt power dissipation capability and 91 V Zener voltage rating. Consider the ±20% tolerance and 75 Ω dynamic impedance for circuit stability requirements. Evaluate thermal management needs given the junction-to-lead thermal resistance specifications for adequate heat sinking.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series provides voltage regulation from 3.3 to 200 volts with various tolerance options identified by suffix letters. The e3 suffix indicates RoHS compliance, while the TR suffix denotes tape and reel packaging per EIA-296 standards.
Replacement Considerations
Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Verify pinout compatibility and thermal performance when substituting axial leads with surface mount packages.
