-100mA / -50V Digital transistors
(with built-in resistors)
DTA144WE / DTA144WUA / DTA144WKA
Applications
Inverter, Interface, Driver
Dimensions (Unit : mm)
EMT3
(SC-75A)
Features
1)Built-in bias resistors enable the configuration of an inverter
circuit without connecting external input resistors.
2)The bias resistors consist of thin-film resistors with complete
isolation to allow positive biasing of the input, and parasitic
effects are almost completely eliminated.
3)Only the on / off conditions need to be set for operation,
making the device design easy.
4)Higher mounting densities can be achieved.
