DTC144EEB Transistors 100mA / 50V Digital transistors (with built-in resistors) DTC144EEB zApplications Inverter, Interface, Driver zDimensions (Unit : mm) EMT3F 1.6 zFeatures 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) 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. 3) Only the on/off conditions need to be set for operation, making the device design easy. 0.7 0.45 1.6 0.86 0.37 0.26 (1) 0.5 0.5 1.0 0.45 0.37 (3) (2) 0.13 Each lead has same dimensions (1) IN (2) GND (3) OUT zStructure NPN silicon epitaxial planar transistor type (Resistor built-in) Abbreviated symbol : 26 zEquivalent circuit OUT R1 IN R2 zPackaging specifications Package EMT3F Packaging type Taping Basic ordering unit (pieces) OUT IN TL Code Part No. GND 3000 GND DTC144EEB R1=R2=47kΩ zAbsolute maximum ratings (Ta=25°C) Parameter Symbol Limits Unit V Supply voltage VCC 50 Input voltage VIN −10 to +40 V ∗1 100 mA 30 mA ∗2 150 mW Collector current Ic(max) Output current Io Power dissipation PD Junction temperature Tj 150 °C Storage temperature Tstg −55 to +150 °C ∗1 Characteristics of built-in transistor ∗2 Each terminal mounted on a recommended land 1/2 DTC144EEB Transistors zElectrical characteristics (Ta=25°C) Parameter Input voltage Output voltage Input current Symbol Min.
