1N5359E3/TR13

Overview

The Microchip Technology 1N5359E3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 24 volts with a standard ±5% tolerance. The device operates within an ambient temperature range of -65°C to +150°C and features RoHS compliance indicated by the e3 suffix. Packaged in a T-18 axial lead case, it utilizes tape and reel packaging for automated assembly.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify that the component matches the specific 24V Zener voltage rating and 5W power dissipation requirements. Confirm the presence of the e3 suffix for RoHS compliance and TR suffix for tape and reel packaging. Ensure the manufacturer designation aligns with Microchip Technology or its acquired entities such as Microsemi. Check datasheet specifications for thermal resistance and maximum current limits relative to your heat sinking capabilities.

Selection Notes

Select this component when a robust 5-watt axial Zener diode is required for high-power regulation tasks. Consider the wide operating temperature range and low thermal resistance for environments requiring reliable performance under thermal stress. Evaluate the need for standard ±5% tolerance against tighter precision requirements available with other suffixes. Ensure the package dimensions fit the designated PCB layout constraints.

Part Context

This part belongs to the extensive 1N5333B through 1N5388B series of silicon Zener diodes originally developed by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3 to 200 volts, offering various tolerance options via specific suffix letters. The e3 designation indicates lead-free construction compliant with environmental standards, while the TR suffix specifies the reel packaging format for manufacturing efficiency.

Replacement Considerations

Direct substitutes include other 1N5359 variants with compatible tolerances (e.g., 1N5359A, 1N5359C) provided they meet the 24V and 5W specifications. Cross-manufacturer equivalents must be verified for identical pinout, power dissipation, and thermal characteristics.
