1N5226BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5226BUR-1/TR is a surface mount Zener diode with a nominal voltage of 3.3 V and a power dissipation rating of 0.5 W. It features a 5% voltage tolerance, a maximum reverse leakage current of 25 µA, and a dynamic impedance of 28 Ohms at a test current of 20 mA. The device operates within a temperature range of -65°C to +175°C and utilizes a DO-213AA (MELF) package.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass surface mount package
• Surface mount equivalent to JEDEC registered axial-leaded series
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• ESD protection in sensitive circuits
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status and screening level. Confirm that the TR suffix indicates tape and reel packaging per EIA-481-B standards. Ensure the component matches the required voltage tolerance and thermal characteristics for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required as a direct replacement for traditional axial leads. Consider the low capacitance and radiation hardness for specialized environments. Verify that the 0.5 W power dissipation and 28 Ohm impedance meet the circuit requirements.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of 0.5 watt Zener voltage regulators. These devices provide surface mount equivalents to popular JEDEC registered axial-leaded parts, offering a wide selection of voltages from 2.4 to 200 volts in a compact MELF-style package.

Single Zener Diodes Replacement Considerations

Direct surface mount replacements include other parts within the 1N5221BUR-1 to 1N5281BUR-1 series. For axial lead equivalents, refer to the standard 1N5221 to 1N5281B series.
