1N483BUR

Overview

The Microchip Technology 1N483BUR is a surface-mount general-purpose switching diode housed in the DO-213AA (SMB) package. It features a maximum repetitive peak reverse voltage of 225 V and a continuous forward current rating of 50 mA. The device dissipates up to 500 mW of power and exhibits a maximum forward voltage drop of 1 V at rated current. It supports a surge current of 2 A and operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

• Surface-mount construction in a compact DO-213AA package for automated assembly
• High thermal stability with an extended operating temperature range up to 175 °C
• General-purpose rectification capability with standard recovery characteristics

Applications

• Signal processing circuits requiring fast switching
• Computer logic interface protection
• General-purpose rectification in low-power electronics

Procurement Notes

Verify the specific suffix BUR against the manufacturer's official documentation to confirm the surface-mount DO-213AA configuration, as generic 1N483 designations often refer to through-hole variants. Ensure the procurement source provides valid traceability data for this Microchip component. Confirm RoHS compliance status directly from the datasheet, as historical production runs may vary in environmental certification.

Selection Notes

Select the 1N483BUR when a surface-mount solution is required for applications needing 225 V reverse blocking capability. This part serves as the SMB-packaged equivalent to the axial 1N483 series. Designers must account for the 50 mA current limit and ensure adequate thermal management for the 500 mW dissipation rating in enclosed environments.

Part Context

This component belongs to the Microchip 1N483 family of silicon planar switching diodes. While the standard 1N483 typically utilizes a DO-35 or DO-7 through-hole package, the BUR suffix denotes the surface-mount variant. These devices are engineered for high reliability in demanding electronic environments, maintaining performance across wide temperature fluctuations.
