1N485BUR

Overview

The Microchip Technology 1N485BUR is a surface-mount switching diode housed in the DO-213AA (SMB) package. It features a maximum DC reverse voltage of 180 V and an average rectified forward current of 100 mA. The device exhibits a maximum forward voltage of 1 V at 100 mA and a reverse leakage current of 25 nA at 180 V. Operating junction temperature ranges from -65°C to 175°C.

Feature Summary

Hermetically sealed metallurgically bonded construction
Double plug design for reliability
Surface mount axial leadless configuration

Applications

High-reliability computer circuits
Signal switching applications
General purpose rectification in harsh environments

Procurement Notes

Verify the specific suffix BUR against official Microchip documentation to confirm surface mount packaging and hermetic sealing specifications. Ensure compatibility with DO-213AA footprints. Confirm RoHS status requirements as legacy variants may differ. Validate that the selected component meets the required thermal and electrical ratings for the target application environment before procurement.

Selection Notes

Select this component when hermetic sealing and high-temperature operation up to 175°C are required in a surface mount form factor. Compare against through-hole equivalents like the 1N485 if PCB layout constraints allow. Verify that the 100 mA current rating and 180 V blocking voltage align with circuit demands. Consider the LL485B or CDLL485B alternatives if different package styles are preferred.

Part Context

This part belongs to the 1N485 family of general-purpose silicon planar switching diodes manufactured by Microchip Technology. The series is characterized by high reliability and stability, often utilized in military and aerospace contexts due to its hermetic construction. The BUR suffix specifically denotes the surface mount variant within this established product line.
