Description: Vintage Monsanto MV1 First Commercially available LED Historic and Collectible In Original Operating Condition ~ Lot of 1 Piece ~ Description:The Monsanto MV1, released in 1968, is considered by most LED collectors to be the world's first commercially produced visible light emitting diode. As can be expected, the MV1 bears only a loose resemblance to a modern epoxy-packaged LED. The semiconductor material is packaged in a gold plated metal can, similar to the TO-18 can packages used for many transistors. There is no reflector as seen in later LEDs. The diode die is mounted directly to a characteristic 'anvil head' contact surface in the bottom of the package, a technique that can be seen in many first generation LEDs. Under magnification, the GaAsP emitting sector can be seen as a circular void surrounded by an upper contact that covers all of the unused space on the top of the die. As expected, the MV1 is a very dim light source, and is barely visible under normal indoor lighting.Own a bit of semiconductor history! ~ US Stock…Fast USA Shipping ~
