WebThe ratio of collector current to emitter current, α=I C /I E. α may be derived from β, being α=β/(β+1). Bipolar transistors come in a wide variety of physical packages. Package type is primarily dependent upon the … Web5 de mar. de 2024 · I would place these transistors in the medium-to-high-power category. They tolerate collector-emitter voltages ranging from 25 V to 100 V, and they have a continuous-collector-current rating of either 2 A or 3 A. Keep in mind, though, that many switching applications involve pulsed load current instead of continuous load current.

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.
