1N5225BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5225BUR-1/TR is a surface-mount Zener voltage regulator with a nominal breakdown voltage of 3.0 V at a test current of 20 mA. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 0.5 W. The device features a hermetically sealed DO-213AA (MELF) package with internal metallurgical bonding. Electrical specifications include a maximum dynamic impedance of 1600 Ohms, a reverse leakage current of 50 µA at 3.0 V, and a temperature coefficient of -0.075 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bond
• Surface mount equivalent to JEDEC registered axial-leaded series
• Inherently radiation hard per Microsemi documentation
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage generation in precision circuits
• Overvoltage protection for sensitive electronic components

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer's nomenclature guide to ensure correct tolerance and compliance levels. Confirm that the TR suffix indicates tape and reel packaging as specified in the mechanical data. Cross-reference the part number with the latest datasheet revisions to validate RoHS status and assembly site information before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for low-voltage regulation applications. Ensure the design accommodates the high dynamic impedance characteristic typical of sub-5V Zener diodes. Verify that the thermal management strategy supports the specified power dissipation limits under worst-case ambient conditions.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which provides surface-mount equivalents to the widely used JEDEC registered 1N5221 to 1N5281 axial series. The series covers a voltage range from 2.4 V to 200 V in a compact metallurgically bonded glass package designed for automated surface-mount assembly processes.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent replacements include the non-suffix 1N5225BUR-1 variant. For axial-leaded requirements, the 1N5225B-1 serves as the corresponding through-hole alternative within the same product family.
