Overview
The DTA114YU3T106 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in a UMT3 (SOT-323) surface-mount package. It integrates bias resistors to simplify circuit design without external components. Key electrical parameters include a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features an input resistance (R1) of 10 kΩ and an emitter-base resistance (R2) of 47 kΩ. It operates with a power dissipation of 200 mW and supports a maximum operating temperature of +150°C.
Feature Summary
- Integrates built-in bias resistors to eliminate the need for external resistors in inverter circuits.
- Provides compact surface-mount packaging suitable for space-constrained applications.
- Supports high-temperature operation up to +150°C.
Applications
- Inverter circuits requiring simplified input stages.
- General-purpose switching applications in consumer electronics.
- Driver circuits for low-power loads.
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific tape-and-reel quantities prior to ordering. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain device integrity during assembly.
Selection Notes
Select this component for designs requiring a PNP digital transistor with a 10 kΩ input resistor and 47 kΩ emitter-base resistor. Verify that the -50 V collector-emitter voltage rating meets the circuit's supply requirements. Consider the UMT3 package dimensions for PCB layout constraints.
Part Context
This part belongs to the DTA114 series of PNP digital transistors from ROHM Semiconductor. The series offers various resistor configurations within the same SOT-323 footprint, allowing designers to choose specific R1/R2 ratios for different gain and drive requirements while maintaining consistent physical integration.
Replacement Considerations
DTA114EU3T106: PNP digital transistor with 10 kΩ R1 and 10 kΩ R2 in SOT-323. DTA114GU3T106: PNP digital transistor with 10 kΩ R1 only in SOT-323. DTC114YUAT106: NPN variant with similar voltage ratings but opposite polarity.
