Soviet 2L101B  
Written by Accutron on 2017-03-24  

Possibly the most primitive production semiconductor ever manufactured, the 2L101B is a rare Soviet military silicon carbide LED. The 2L101B consists of a silicon carbide die, sandwiched between two leads and packed in a minuscule droplet of glass. This device has a slightly greenish yellow glow compared to conventional GaAsP yellow LEDs, and is incredibly dim.
