Overview
The DTC043TEBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring a built-in base resistor (R1) of 4.7 kOhms. It operates with a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device has a maximum power dissipation of 150 mW and a transition frequency of 250 MHz. It is housed in an EMT3F (SOT-416FL) surface-mount package. The DC current gain (hFE) is specified as a minimum of 100 at 5 mA and 10 V. The component supports a maximum operating temperature of +150 °C and complies with RoHS standards.
Feature Summary
- Integrates a single bias resistor to simplify circuit design
- Provides high-speed switching capability up to 250 MHz
- Offers compact surface-mount packaging for space-constrained applications
Applications
- General-purpose digital switching circuits
- Interface circuits between logic gates and loads
- Driver stages for small-signal relay or LED control
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure that the procurement documentation explicitly references the DTC043TEBTL part number to avoid confusion with similar series members like DTC043TE or DTC043ZEBTL. Confirm RoHS compliance status through official certification documents provided by ROHM Semiconductor prior to finalizing orders.
Selection Notes
Select this component when a single-resistor NPN digital transistor is required for low-power switching applications. The 4.7 kOhm internal resistor value suits standard logic interface voltages. Consider the 150 mW power dissipation limit and SOT-416FL thermal characteristics during PCB layout. Verify that the 50 V collector-emitter rating meets the circuit's voltage requirements and that the 100 mA current capacity is sufficient for the intended load.
Part Context
This component belongs to the DTC043 series of digital transistors from ROHM Semiconductor. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. The DTC043TEBTL specifically denotes the single-resistor configuration within the broader family of bias resistor transistors offered by the manufacturer.
Replacement Considerations
Publicly confirmed substitute part numbers include DTC043TE and DTC043TEB. Verify pinout compatibility and electrical parameter equivalence before substitution.
