1N5381CE3/TR12

Overview

The Microsemi Corporation 1N5381CE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in an axial-lead T-18 package with tape and reel packaging. It provides a nominal Zener voltage of 130 V with a tight tolerance of ±2%, as indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the 'e3' suffix. Electrical characteristics include a maximum reverse current of 0.5 µA at 93.6 V and a maximum dynamic impedance of 190 ohms.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring high power dissipation
• Protection against high surge stresses in electronic systems
• Applications necessitating precise voltage tolerances with tight regulation

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'C' indicates ±2% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' denotes tape and reel packaging. Confirm the manufacturer designation as Microsemi Corporation or its authorized successor entities. Ensure the component meets the specified JEDEC registration standards for the 1N5333B through 1N5388B series before procurement.

Selection Notes

Select this component when a 5-watt power rating and a 130 V Zener voltage are required. The ±2% tolerance makes it suitable for precision applications compared to standard B or A suffix variants. Consider the T-18 axial lead package for through-hole mounting and verify thermal management requirements given the 25°C/W junction-to-lead thermal resistance.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi Corporation. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by specific suffix letters. These plastic encapsulated devices are designed for high maximum DC currents with adequate heat sinking.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 through SMBJ5388B or SMBG5333B through SMBG5388B are available from the same manufacturer family.
