DTA144VKA / DTA144VSA Transistors Digital transistor (built-in resistors) DTA144VKA / DTA144VSA zExternal dimensions (Unit : mm) (2) (3) 0.4 (1) DTA144VKA 0.95 0.95 1.9 2.9 zFeatures 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 device design easy. 4) Higher mounting densities can be achieved. 1.6 0~0.1 ROHM : SMT3 EIAJ : SC-59 0.3Min.
