1N5359BE3/TR12

Overview

The Microchip Technology 1N5359BE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 24 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 17.3 V and a dynamic impedance of 3.5 Ω at a test current of 50 mA. The component utilizes a T-18 axial lead package and is supplied in tape and reel format.

Feature Summary

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

Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• General-purpose voltage reference applications

Procurement Notes

Verify the specific suffix configuration to ensure compliance with RoHS requirements and tape-and-reel packaging standards. Confirm that the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity and traceability for this JEDEC registered series component.

Selection Notes

Select this component when a 5-watt power dissipation rating and a 24 V regulation point are required. Ensure adequate heat sinking is provided to maintain operation within the specified thermal resistance limits. Verify that the ±5% tolerance aligns with the circuit's precision requirements.

Part Context

This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes. Manufactured by Microsemi (now part of Microchip Technology), these components are designed for high reliability in demanding environments, offering a wide selection of voltages from 3.3 V to 200 V in a plastic encapsulated axial-lead package.

Replacement Considerations

Compatible substitutes include other 5 W Zener diodes with a 24 V nominal voltage and ±5% tolerance in a T-18 package. Verify equivalent thermal resistance and surge current ratings before substitution.
