NPN Digital Transistors (Built-in Resistors) DTD143EN3 Features • Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). • The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. • Only the on/off conditions need to be set for operation, making device design easy. • Complements the DTB143EN3 Equivalent Circuit Outline SOT-23 DTD143EN3 R1=4.7kΩ , R2=4.7 kΩ IN(B) : Base OUT(C) : Collector GND(E) : Emitter Absolute Maximum Ratings (Ta=25℃) Parameter Supply Voltage Input Voltage Output Current Power Dissipation Junction Temperature Storage Temperature DTD143EN3 Symbol Limits Unit VCC VIN IO Pd Tj Tstg 50 -10~+30 500 200 150 -55~+150 V V mA mW °C °C CYStek Product Specification CYStech Electronics Corp.
