DTB122JK Transistors Digital transistor (built-in resistors) DTB122JK z Circuit schematic z Features 1) Built-in bias resistors enable the configuration of an R1 OUT IN inverter circuit without connecting external input R2 resistors. GND (+) 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input, IN OUT GND (+) 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. z Absolute maximum ratings (Ta=25C) Parameter Symbol Limits Unit Supply voltage VCC 50 V Input voltage VI 5 to +5 V Output current IO 500 mA Power dissipation Pd 200 mW Junction temperature Tj 150 C Storage temperature C Tstg 55 to +150 z Package, marking, and packaging specifications Part No. DTB122JK Package SMT3 Marking G3C Packaging code T146 Basic ordering unit (pieces) 3000 z External characteristics (Ta=25C) Parameter Symbol Min.
