Overview
DTA143TETL is a PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device features a typical input resistance (R1) of 10 kOhms and a maximum power dissipation (PD) of 150 mW. It operates within a temperature range of -55°C to +150°C and offers a transition frequency (fT) of up to 250 MHz.
Feature Summary
- Integrates built-in bias resistors to enable inverter circuit configuration without external input components.
- Utilizes thin-film resistors with complete isolation to minimize parasitic effects and allow positive input biasing.
- Simplifies design process by requiring only on/off condition settings for operation.
Applications
- Inverter circuits
- Interface logic
- Driver stages
Procurement Notes
Verify the specific suffix 'TL' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the component meets RoHS compliance requirements for the intended application environment. Cross-reference the ordering code with authorized distributors to confirm availability and lead times prior to procurement.
Selection Notes
Select this PNP variant when a negative supply rail or high-side switching configuration is required. The integrated 10 kOhm input resistor reduces board space and component count compared to discrete solutions. Verify that the -50 V breakdown voltage and -100 mA current rating exceed the maximum operational loads in the target circuit design.
Part Context
The DTA143TETL belongs to the DTA143 series of pre-biased transistors from ROHM Semiconductor. This series is designed for general-purpose switching applications where space efficiency and simplified biasing are priorities. The EMT3 package provides a compact footprint suitable for dense surface-mount assemblies.
Replacement Considerations
Compatible substitutes include DTA143TE and DTA143TM, which share similar electrical characteristics and pinouts. Verify pin compatibility and thermal performance before substituting. Ensure the alternative part number meets the same voltage and current ratings as specified in the original design requirements.
