DTD114GK
Transistors
500mA / 50V Digital transistors
(with built-in resistors)
DTD114GK
Applications
Inverter, Interface, Driver
Feature
1) The built-in bias resistors consist of thin-film resistors
with complete isolation to allow negative biasing of
the input, and parasitic effects are almost completely
eliminated.
2) Only the on / off conditions need to be set for
operation, making the device design easy.
3) Higher mounting densities can be achieved.
