1N5363E3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5363E3/TR12 is a silicon Zener diode with a nominal voltage of 30V and a power dissipation rating of 5.0 watts at 25°C. It features a ±5% tolerance indicated by the B suffix, housed in an axial-lead T-18 package. The device operates within a temperature range of -65°C to +150°C and includes RoHS compliance via the e3 suffix. Tape and reel packaging is provided through the TR12 suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• General-purpose voltage reference designs

Single Zener Diodes Procurement Notes

Verify that the part number matches the specific JEDEC registered series requirements. Confirm the presence of the e3 suffix for RoHS compliance and the TR12 suffix for tape and reel packaging. Ensure the B suffix corresponds to the required ±5% voltage tolerance before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial-leaded Zener diode is required. The 30V nominal voltage and ±5% tolerance suit standard regulation needs. Consider thermal derating curves if ambient temperatures exceed 25°C or if mounted on FR4 PCBs without adequate heat sinking.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different tolerances are identified by specific suffix letters on the part number, allowing for precise selection based on circuit requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N5363 variants with different suffixes for tolerance or packaging. Surface mount equivalents such as SMBJ5363B or SMBG5363B are available for space-constrained designs.
