Bipolar Junction Transistors, or BJTs, offer higher trans-conductance than MOSFETS and don't require separate gate drivers. A particular strength is that they are current amplifiers capable of very high current densities. They can be used as amplifiers, switches, and oscillators and are capable of very high frequency operation. They can also be used as temperature sensors and logarithmic converters. Microsemi offers BJTs in a discrete NPN or PNP configuration, and also assembled in several that can be used for Interface or Power Conversion Applications.
