Overview
The DTA144EETL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -0.1A. The device includes an input resistance (R1) of 47kΩ and an emitter-base resistance (R2) of 47kΩ, providing a resistor ratio of 1. Key electrical parameters include a power dissipation of 0.15W, a DC current gain (hFE) ranging from 68 to 600, and a transition frequency of 250MHz. It is housed in the EMT3 (SOT-416) surface-mount package.
Feature Summary
- Integrates built-in biasing resistors to eliminate external components and reduce board space.
- Offers high-speed switching capabilities suitable for logic interface applications.
- Provides a compact surface-mount footprint for dense PCB layouts.
Applications
- Logic level shifting between different voltage domains.
- Inverter circuits in digital control systems.
- Driver stages for small-signal loads in consumer electronics.
Procurement Notes
Verify the specific suffix 'TL' against the manufacturer's latest datasheet to confirm tape-and-reel packaging details and quantity per reel. Ensure compliance with RoHS directives and check for any end-of-life notices or recommended new design alternatives prior to final procurement authorization.
Selection Notes
Select this component when a PNP configuration with a 47kΩ/47kΩ resistor ratio is required. Consider the -50V voltage rating and 100mA current limit for load compatibility. Evaluate the EMT3 package size constraints against available board real estate and thermal dissipation requirements for the target application environment.
Part Context
This part belongs to ROHM's standard digital transistor series, which combines transistors and resistors into single packages. It serves as a complementary counterpart to NPN types like the DTC144EE. The series is designed to replace discrete resistor-transistor combinations in general-purpose switching applications.
Replacement Considerations
DTA144EE is the base model variant. For automotive-grade requirements, consider the DTA144EUBHZG, which supports AEC-Q101 standards but uses a UMT3F package. Verify pinout and parameter equivalence before substitution.
