Overview
The DTA144TMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SMD/SMT VMT3 (SOT-723) package. It operates with a maximum collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes a typical input resistance of 47 kOhms and maintains a minimum DC current gain of 68 at specified test conditions. Power dissipation is rated at 150mW, with a maximum operating temperature of +150°C and a transition frequency of 250MHz.
Feature Summary
- Integrates pre-biased resistors to simplify circuit design and reduce component count
- Optimized for high-speed switching applications with a 250MHz transition frequency
- Designed for surface-mount assembly in compact electronic systems
Applications
- Interface circuits for logic level translation
- Driver stages for small-signal loads
- Switching elements in portable battery-powered devices
Procurement Notes
Verify the specific suffix TMT2L against official ROHM documentation to confirm tape-and-reel packaging and exact resistor values. Ensure compatibility with standard SMT reflow profiles and check for automotive qualification status if required for the target application environment.
Selection Notes
Select this component when a compact PNP solution with integrated biasing is needed. Compare the 47kOhm input resistance and 150mW power rating against circuit requirements. Consider the SOT-723 footprint constraints and thermal management capabilities during layout planning.
Part Context
This part belongs to the ROHM DTx series of digital transistors, which combine bipolar junction transistors with internal resistors. The DTA144 variant specifically denotes a PNP configuration with defined resistor ratios, widely used in consumer electronics and industrial control modules requiring space-efficient switching components.
Replacement Considerations
Check for direct substitutes such as DTA144EMT2L or DTA144TU3T106 based on package compatibility and electrical parameter alignment. Verify that alternative parts match the -50V voltage rating and 100mA current capacity before implementation.
