DTA143EEB Transistors -100mA / -50V Digital transistors (with built-in resistors) DTA143EEB 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) (1) IN (2) GND (3) OUT 0.13 Each lead has same dimensions Abbreviated symbol : 13 zStructure PNP silicon epitaxial planar transistor type (Resistor built-in) zEquivalent circuit OUT R1 IN R2 zPackaging specifications Package EMT3F Packaging type Taping TL Code Part No. GND(+) Basic ordering unit (pieces) OUT IN 3000 GND(+) DTA143EEB R1=R2=4.7kΩ zAbsolute maximum ratings (Ta=25°C) Parameter Symbol Limits Unit V Supply voltage VCC −50 Input voltage VIN −30 to +10 V −100 mA Collector current Ic(max) Output current Io Power dissipation PD ∗1 ∗2 −100 mA 150 mW 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 DTA143EEB Transistors zElectrical characteristics (Ta=25°C) Parameter Input voltage Output voltage Symbol Min.
