We also ask that you refer to MatWeb’s terms of use regarding datasheeet information. When no base voltage is applied that when is no signal is given to the input pins of the ICthere will be no base current and transistor remains in off state. A Darlignton pair is two transistors that act as a single transistor providing high current gain. Property Data This page displays only the text of a material data sheet.

In this pair the current amplified by the first transistor is further amplified by the next transistor providing high datssheet to the output terminal. Data sheets for overmetals, plastics, ceramics, and composites. We appreciate your input.
