1N5362/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5362/TR12 is a silicon Zener diode with a nominal voltage of 28 V and a power dissipation rating of 5 W. It features a ±5% voltage tolerance, a maximum reverse leakage current of 0.5 µA at 20.1 V, and a dynamic impedance of 6.0 Ω. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 (DO-201AE) axial lead package.

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 exhibits minimal voltage change versus current

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the component origin as this part number originates from the Microsemi Scottsdale Division, which is now part of Microchip Technology. Confirm RoHS compliance status by checking for the e3 suffix, as standard versions may not meet current environmental standards. Ensure the TR12 tape and reel packaging matches your automated assembly requirements.

Single Zener Diodes Selection Notes

Select this component when a 28 V regulation point is required with a 5 W power handling capability. The B suffix indicates a standard ±5% tolerance suitable for general-purpose applications. Consider thermal derating curves if operating above 25°C ambient or without adequate heat sinking on FR4 PCBs.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5362 variant specifically targets the 28 V regulation segment within this high-power axial-leaded family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N5362 variants such as 1N5362B or 1N5362BE3. Surface mount equivalents like SMBJ5362B or SMBG5362B are available for different form factors.
