Overview
The Microsemi Corporation 1N5377AE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial T-18 package with tape and reel packaging. It provides a nominal Zener voltage of 91 V with a ±10% 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. Reverse leakage current is limited to 500 µA at 65.5 V.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for through-hole integration
- Withstands high surge stresses and exhibits minimal voltage change versus current
- RoHS compliant construction with void-free transfer molded epoxy body
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement instrumentation
Procurement Notes
Verify the specific suffix configuration against the official datasheet to confirm tolerance and packaging requirements. Confirm that the TR8 designation aligns with the required tape and reel specifications for automated assembly processes. Ensure compatibility with existing thermal management designs given the 5-watt power dissipation rating.
Selection Notes
Select this component when a 91 V regulation point with ±10% tolerance is required in an axial leaded format. Consider the 5-watt power handling capability and the specified thermal resistance characteristics for heat sinking applications. Verify that the 75 Ohm dynamic impedance meets the circuit's noise and stability requirements.
Part Context
This part belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. The e3 suffix indicates RoHS compliance, while the TR suffix denotes tape and reel packaging availability.
Replacement Considerations
Surface mount equivalents are available as SMBJ5333 through SMBJ5388B or SMBG5333B through SMBG5388B. These surface mount devices offer identical electrical characteristics and testing to the axial-leaded JEDEC registered series.
