DTC143TEB Transistors 100mA / 50V Digital transistors (with built-in resistors) DTC143TEB 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. zStructure NPN silicon epitaxial planar transistor type (Resistor built-in) 0.45 1.6 0.86 0.37 (1) 0.5 0.5 1.0 0.45 0.37 (3) (2) 0.13 (1) Base (2) Emitter (3) Collector Each lead has same dimensions Abbreviated symbol : 03 zEquivalent circuit C zPackaging specifications B Package EMT3F Packaging type Taping R1 E TL Code Part No. 0.7 0.26 B : Base C : Collector E : Emitter 3000 Basic ordering unit (pieces) DTC143TEB R1=4.7k zAbsolute maximum ratings (Ta=25C) Parameter Symbol Limits Unit Collector-Base voltage VCBO 50 V Collector-Emitter voltage VCEO 50 V Emitter-Base voltage VEBO 5 V 100 mA 150 mW Tj 150 C Tstg -55 to +150 C Collector current IC Power dissipation PD Junction temperature Range of Storage temperature 1 1 Each terminal mounted on a recommended land 1/2 DTC143TEB Transistors zElectrical characteristics (Ta=25C) Parameter Symbol Min.

Products listed in this document are no antiradiation design. The products listed in this document are designed to be used with ordinary electronic equipment or devices (such as audio visual equipment, office-automation equipment, communications devices, electrical appliances and electronic toys). Should you intend to use these products with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life (such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devices), please be sure to consult with our sales representative in advance. It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM cannot be held responsible for any damages arising from the use of the products under conditions out of the range of the specifications or due to non-compliance with the NOTES specified in this catalog.
