Overview
The DTC143TMFHAT2L is an NPN digital transistor from ROHM Semiconductor, featuring a built-in bias resistor configuration in the SOT-723 (VMT3) package. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a single input resistor (R1) of 4.7 kΩ. Key electrical parameters include a DC current gain (hFE) ranging from 100 to 600 at specified conditions, a power dissipation of 150 mW, and a maximum operating temperature of +150°C. The component is designed for surface mount applications.
Feature Summary
- Integrates a thin-film bias resistor directly with the NPN transistor to simplify circuit design by eliminating external input resistors.
- Provides high reliability suitable for automotive applications, qualified to AEC-Q101 standards.
- Features complete isolation between bias resistors to allow positive input biasing and minimize parasitic effects.
Applications
- Inverter circuits
- Interface drivers
- General-purpose driver applications
Procurement Notes
Verify the specific suffix 'FHAT2L' against official ROHM documentation to confirm exact packaging and tape specifications. Ensure compatibility with automated pick-and-place equipment regarding the VMT3 package dimensions. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement.
Selection Notes
Select this component when a compact NPN digital transistor with a 4.7 kΩ base resistor is required for space-constrained designs. Consider the 50 V rating and 100 mA current capacity for low-power switching tasks. Verify that the SOT-723 footprint aligns with the PCB layout constraints compared to larger packages like SOT-23.
Part Context
This part belongs to the DTC143 series of pre-biased transistors manufactured by ROHM Semiconductor. The series offers various configurations including R1 alone or R1/R2 combinations in different packages such as SOT-23 and SOT-723. The DTC143TMFHAT2L specifically utilizes the smaller VMT3 form factor for high-density mounting.
Replacement Considerations
Direct substitutes may include other NPN digital transistors with similar 50 V/100 mA ratings and 4.7 kΩ input resistance in SOT-723 packages, such as parts from ON Semiconductor or STMicroelectronics. Always verify pinout compatibility and thermal characteristics before substitution.
