What is a Darlington Transistor?
A Darlington transistor, also known as a Darlington pair, consists of a pair of bipolar transistors that are connected in order to provide a very high-current gain from a low-base current. In a Darlington transistor, the input transistor’s emitter is wired to the output transistor’s base and their collectors are tied together. Therefore, the current that is amplified by the input transistor is amplified even further by the output transistor.
Types of Darlington Transistors
There are many different kinds of Darlington transistors. At Future Electronics we stock many of the most common types categorized by Polarity, Power Dissipation, Collector Current @ 100C, Maximum CE Voltage, Packaging Type and Minimum DC Current Gain. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common values for Maximum CE Voltage are 30 V, 60 V, 80 V and 100 V. We also carry Darlington transistors with Maximum CE Voltage as high as 450 V. Power Dissipation can be between 200 mW and 250 W, with 2 W being the most common value.
