1N5281BDO35TR

Single Zener Diodes Overview

The Microsemi Corporation 1N5281BDO35TR is a Zener diode with a nominal voltage of 200V and a tolerance of ±5%. It operates within a power dissipation range up to 0.5 watts at 25°C, utilizing a DO-35 glass axial-lead package. The device supports an operating temperature range from -65°C to +175°C and features hermetic sealing. The TR suffix indicates tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• Inherently radiation hard per MicroNote 050
• Flexible axial-lead mounting terminals
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Military screening applications requiring JAN, JANTX, JANTXV, or JANS levels
• High-reliability electronic circuits requiring radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against official Microsemi documentation to confirm exact electrical tolerances and screening levels. Ensure the TR suffix requirement matches automated assembly equipment specifications. Confirm RoHS compliance status if lead-free plating is required for the project.

Single Zener Diodes Selection Notes

Select this component when high-voltage regulation near 200V is required in a standard DO-35 package. Consider the ±5% tolerance for general regulation tasks. Evaluate thermal derating requirements based on the specified junction-to-lead thermal resistance values for the intended PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5-watt Zener Voltage Regulators manufactured by Microsemi's Scottsdale Division. The series provides a wide selection of voltages from 2.4 to 200 volts with various tolerance options identified by suffix letters.

Single Zener Diodes Replacement Considerations

Consult the manufacturer for surface mount equivalents in the MLL5221 to MLL5281B series packaged in DO-213AA MELF style. Verify compatibility with alternative manufacturers offering JEDEC registered 1N5281 types in DO-35 packages.
