Overview
The Microsemi Corporation 1N5387E3/TR13 is a silicon Zener diode with a nominal voltage of 190V and a tolerance of ±20%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes a T-18 axial leaded plastic package and includes an e3 suffix indicating RoHS compliance. Packaged in tape and reel format per EIA-296 standards, it provides stable voltage regulation across broad current ranges.
Feature Summary
- Provides stable voltage regulation over a wide operating current and temperature range
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Features flexible axial-lead mounting terminals for secure installation
- Moisture classification Level 1 requiring no dry pack storage
Applications
- Voltage regulation circuits
- Surge protection applications
- General purpose electronic equipment
Procurement Notes
Verify the specific part number against official Microsemi documentation to confirm RoHS compliance status and JEDEC registration details. Ensure the ordering suffix matches the required packaging configuration and screening level. Cross-reference datasheet electrical characteristics to validate suitability for the intended thermal and voltage conditions.
Selection Notes
Select this component based on its 5-watt power rating and 190V breakdown voltage requirements. Consider the T-18 axial package for through-hole mounting needs. Evaluate thermal resistance specifications to ensure adequate heat sinking for steady-state operation. Confirm that the ±20% tolerance aligns with circuit precision requirements.
Part Context
This component belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a broad selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments.
Replacement Considerations
Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the base part numbers.
