1N5387E3/TR12

Overview

The Microsemi Corporation 1N5387E3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 190 V and ±5% tolerance. It features an axial-lead T-18 plastic package, operates from -65°C to +150°C, and has a maximum dynamic impedance of 450 ohms at 5.0 mA test current. The device includes RoHS compliance (e3 suffix) and tape-and-reel packaging (TR suffix).

Feature Summary

Provides stable voltage regulation across broad operating currents and temperature ranges.
Withstands high surge stresses and offers flexible axial-lead mounting terminals.
Features low thermal resistance design for operation at high maximum DC currents.
Moisture classification Level 1 requires no dry pack handling.

Applications

Voltage regulation in power supply circuits.
Overvoltage protection for sensitive electronic components.
Reference voltage generation in measurement equipment.

Procurement Notes

Verify the specific ordering suffixes against official datasheets to confirm RoHS compliance and tape-and-reel packaging requirements. Confirm that the component meets all JEDEC registration standards and environmental classifications before finalizing procurement specifications.

Selection Notes

Select this component when a 190 V Zener voltage with tight ±5% tolerance is required. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits during continuous operation.

Part Context

This part belongs to the 1N5333B through 1N5388B series of JEDEC registered axial-leaded 5.0 watt Zener diodes. The series provides a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters on the part number.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Cross-reference electrical characteristics and mechanical dimensions to ensure compatibility with existing circuit designs.
