In this pair the current amplified by the first transistor is further amplified by the next transistor providing high current to the output terminal.


A Darlignton pair is two transistors that act as a single transistor providing high current gain.

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.

Designed for extrusion and injection molding applications. Thic IC consists of a eight NPN Darlington connected transistors with common Clamp diodes for switching the loads connected to the output.
