1N5260BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5260BUR-1/TR is a surface mount Zener diode in the 1N5221BUR-1 to 1N5281BUR-1 series. It provides a 43 V nominal Zener voltage with a ±5% tolerance at a test current of 3.0 mA. The device dissipates up to 0.5 W and operates within a junction temperature range of -65°C to +175°C. It features a hermetically sealed DO-213AA (MELF) package with an internal metallurgical bond, offering low capacitance and radiation hardness.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bond
• Inherently radiation hard per Microsemi specifications
• Non-sensitive to electrostatic discharge
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic circuits requiring radiation hardness
• Surface mount equivalents for JEDEC registered axial-leaded series

Single Zener Diodes Procurement Notes

Verify that the TR suffix indicates tape and reel packaging per EIA-481-B standards. Confirm RoHS compliance status as it applies only to commercial grade versions. Ensure the specific part number matches the required 43 V Zener voltage and ±5% tolerance parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent to the 1N5260B axial series is required. The DO-213AA package supports automated assembly processes. Consider the maximum power dissipation limits and thermal resistance values when designing heat management strategies for the application environment.

Single Zener Diodes Part Context

This component belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of 0.5 watt Zener voltage regulators. These devices provide surface mount options for voltages ranging from 2.4 to 200 volts. The series maintains compatibility with traditional JEDEC registered part numbers while utilizing a metallurgically bonded glass configuration.

Single Zener Diodes Replacement Considerations

The 1N5260B is the axial-leaded equivalent. For parameter-matched replacements, verify the 43 V Zener voltage, 500 mW power rating, and DO-213AA package dimensions.
