1N5381AE3/TR12

Overview

The Microsemi Corporation 1N5381AE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 130 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 190 Ohms and a maximum reverse current of 0.5 µA. RoHS compliance is confirmed by the 'e3' suffix.

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 changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring 130 V reference
• Power supply protection against high surge stresses
• Electronic systems operating in wide temperature environments

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'A' indicates ±10% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' specifies tape and reel packaging. Confirm the manufacturer designation as Microsemi Corporation or its 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 130 V Zener voltage with ±10% tolerance is required for through-hole assembly. The 5.0-watt power dissipation rating necessitates adequate heat sinking for operation at maximum DC currents. Consider the T-18 package dimensions and thermal resistance characteristics for PCB layout. Verify compatibility with the specific moisture classification and soldering temperature limits defined in the datasheet.

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 suffix letters. These plastic encapsulated devices are designed for applications requiring robust performance under high surge stresses and wide temperature variations.

Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series. Other manufacturers may offer compatible 5-watt Zener diodes with similar electrical characteristics, but mechanical dimensions and thermal properties must be verified for direct substitution.
