Overview
The DTA043TEBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors within an EMT3F (SOT-416FL) surface-mount package. It operates with a collector-emitter voltage of -50 V and a maximum collector current of -100 mA. The device incorporates a base resistor (R1) of 4.7 kΩ and an emitter-base resistor (R2) of 10 kΩ. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at 5 mA and 10 V, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. The component supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Integrates dual thin-film bias resistors to simplify circuit design by eliminating external input components.
- Provides complete isolation between resistors and the transistor to minimize parasitic effects.
- Enables straightforward on/off switching operations for interface and driver applications.
Applications
- Inverter circuits
- Interface logic
- Driver stages
Procurement Notes
Verify the specific suffix against official Rohm documentation to confirm exact resistance values and packaging configuration. Ensure compliance with RoHS standards and check for automotive qualification restrictions if applicable. Confirm lead times and availability through authorized distributors as standard products may have varying supply statuses.
Selection Notes
Select this component for designs requiring compact PNP switching with integrated biasing. Verify that the 4.7 kΩ base resistor and 10 kΩ emitter-base resistor align with the target logic levels. Ensure the SOT-416FL footprint matches the PCB layout constraints and thermal requirements are met within the 150 mW dissipation limit.
Part Context
This part belongs to Rohm's standard digital transistor series, designed for general-purpose switching. It is distinct from other variants in the DTA043 family which may feature different resistor ratios or NPN polarity. The EMT3F package offers a small form factor suitable for high-density surface mount assemblies.
Replacement Considerations
Check for direct substitutes such as DTA043ZEBTL for PNP variants with similar specifications. Verify pinout compatibility and electrical parameters before substitution. Consult official cross-reference lists for confirmed equivalents.
