1N5362A/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5362A/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation applications. It features a T-18 axial-lead package with a plastic encapsulated body and operates within a temperature range of -65°C to +150°C. The device provides a nominal Zener voltage of 28V with a standard tolerance of ±10%, as indicated by the 'A' suffix. Electrical characteristics include a maximum dynamic impedance of 6.0 ohms at a test current of 50mA and a maximum reverse leakage current of 0.5µA. The component supports high surge currents and offers flexible mounting terminals.

Single Zener Diodes 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 versatile integration
• Operates reliably without sensitivity to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation in electronic instrumentation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as this part number originates from the Microsemi Scottsdale Division which has undergone corporate restructuring. Confirm that the TR8 suffix correctly denotes tape and reel packaging per EIA-296 standards. Ensure compatibility with RoHS compliance requirements if applicable to your assembly process. Validate that the ±10% tolerance aligns with your circuit design specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 28V regulation point is required with moderate precision. The 5-watt power dissipation rating allows operation at high DC currents provided adequate heat sinking is implemented. Consider the T-18 through-hole package for mechanical robustness. Evaluate thermal resistance parameters against your PCB layout constraints to ensure steady-state power limits are not exceeded during continuous operation.

Single Zener Diodes Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. Different suffix letters identify specific voltage tolerances, with 'A' denoting ±10%. The series is JEDEC registered and utilizes void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 flammability ratings.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5362B (±5% tolerance) or 1N5362C (±2% tolerance) from the same series. Surface mount equivalents such as SMBJ5362B or SMBG5362B are available for space-constrained designs. Verify that substitute components match the 5-watt power rating and T-18 package dimensions for direct interchangeability.
