ON Semiconductor – datasheet pdf

In this pair the current amplified by the first 2803s is further amplified by the next transistor providing high current to the output terminal. We also ask that you refer to MatWeb’s terms of use regarding this information.

Thic IC consists of a eight NPN Darlington connected transistors with common Clamp diodes for switching the loads connected to the output. Thus when an input is applied corresponding output pin drops down to zero there by enabling the load connected to complete its path.

Designed for extrusion and injection molding applications. We appreciate your input. This IC is widely used to drive high loads such Lamps, relays, motors etc. The contents, results, and technical data from this site may not be reproduced either electronically, photographically or substantively without permission from MatWeb, LLC.

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 catasheet. Data sheets from materials that are no longer available remain in MatWeb to assist users in finding replacement materials.

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