1N5362B/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5362B/TR8 is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 28 V. It operates within a temperature range of -65°C to +150°C and features a maximum power dissipation of 5.0 watts at 25°C ambient temperature. The device exhibits a maximum dynamic impedance of 6.0 ohms and a maximum reverse current of 0.5 µA. It utilizes the T-18 axial lead package and includes a TR suffix indicating tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and minimal changes in voltage versus current
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection applications
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as this part number appears in datasheets from both Microsemi and onsemi. Confirm RoHS compliance status, as some listings indicate non-compliance while others specify e3 suffixes. Ensure the TR suffix matches the required tape and reel specifications for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 28 V reference point is required with 5 W power handling capabilities. Consider the thermal resistance characteristics and derating curves for heat sinking requirements. Verify that the ±5% tolerance aligns with circuit precision needs compared to tighter tolerance variants.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333 to 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The B suffix indicates standard voltage tolerances of plus or minus 5%. These plastic encapsulated devices are designed for high maximum DC currents with adequate heat sinking.
