DTA144WE / DTA144WUA / DTA144WKA / DTA144WSA Transistors Digital transistors (built-in resistor) DTA144WE / DTA144WUA / DTA144WKA / DTA144WSA 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. zCircuit schematic R1 IN OUT R2 GND(+) IN OUT GND(+) zAbsolute maximum ratings (Ta=25°C) Symbol Limits Unit Supply voltage Input voltage Parameter VCC VI −50 −40 to +10 V V Output current IO IC(Max.) −30 mA DTA144WE Power dissipation DTA144WUA / DTA144WKA DTA144WSA Junction temperature Storage temperature −100 150 Pd 200 300 mW Tj Tstg 150 −55 to +150 C C zPackage, marking, and packaging specifications Part No. DTA144WE DTA144WUA DTA144WKA DTA144WSA Package Marking EMT3 76 UMT3 76 SMT3 76 SPT − Packaging code Basic ordering unit (pieces) TL 3000 T106 3000 T146 3000 TP 5000 Rev.A 1/2 DTA144WE / DTA144WUA / DTA144WKA / DTA144WSA Transistors zElectrical characteristics (Ta=25°C) Parameter Symbol Min.
