Overview
The DTA043XEBTL is a pre-biased PNP digital transistor manufactured by ROHM Semiconductor. It integrates a single bipolar junction transistor with two internal bias resistors (R1 and R2) in a compact surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage of 50 V, a maximum continuous collector current of 100 mA, and a power dissipation rating of 150 mW. The device features a typical base input resistance (R1) of 4.7 kOhms and an emitter-base resistance (R2) of 10 kOhms. It operates within a temperature range of -55 °C to +150 °C and offers a transition frequency of 250 MHz.
Feature Summary
- Integrates dual bias resistors to simplify circuit design by eliminating external components.
- Provides high-density packaging for space-constrained applications.
- Ensures consistent DC current gain characteristics across production batches.
Applications
- General-purpose logic level shifting and interface circuits.
- Driver stages for small-signal switching applications.
- Biasing networks in portable electronic devices.
Procurement Notes
Verify the specific suffix EBTL against the manufacturer's latest datasheet to confirm resistor values and pinout compatibility. Ensure that the ordering documentation explicitly references the EMT3F (SOT-416FL) package type. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement.
Selection Notes
Select this component when a PNP configuration with integrated biasing is required for low-power switching. Compare the 4.7 kOhm base resistance against alternative models if different drive currents are needed. Verify that the 150 mW power dissipation limit accommodates the thermal constraints of the target PCB layout.
Part Context
This part belongs to the DTA043 series of resistor-equipped bipolar transistors from ROHM. The series includes complementary NPN variants such as the DTC043EEBTL. These components are designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity in consumer electronics.
Replacement Considerations
Direct substitutes include the DTC043EEBTL for NPN applications with similar electrical ratings. Other compatible packages within the same family may offer identical functionality with different form factors. Verify pin compatibility before swapping between SOT-416FL and other small outline packages.
