1N5359A/TR8

Overview

The Microchip Technology 1N5359A/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 24V and ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5µA at 17.3V and a dynamic impedance of 3.5Ω at a test current of 50mA. The component utilizes an axial-lead T-18-2 package and is supplied in tape-and-reel format.

Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Withstands high surge stresses without damage
• Features flexible axial-lead mounting terminals for through-hole applications
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring 5W power dissipation
• High-voltage reference designs
• Surge protection applications

Procurement Notes

Verify the specific suffix 'TR8' indicates tape-and-reel packaging compatible with automated assembly equipment. Confirm that the 'A' designation strictly corresponds to the ±10% voltage tolerance specified in the datasheet. Ensure procurement channels source directly from authorized distributors to guarantee authenticity and traceability for this JEDEC registered series component.

Selection Notes

Select this component when a 24V regulation point is required with moderate precision. The 5W power rating allows operation at higher currents if adequate heat sinking is provided. Verify that the T-18-2 package dimensions fit the target PCB layout. Consider the thermal resistance characteristics for derating calculations based on the intended mounting method.

Part Context

This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3V to 200V. These plastic encapsulated components are designed for robust performance in demanding environments, offering moisture classification Level 1.

Replacement Considerations

Equivalent parts include other 5W Zener diodes with 24V nominal voltage and ±10% tolerance. Cross-reference must verify identical power dissipation, package type, and electrical characteristics such as dynamic impedance and leakage current.
