Overview
The DTC143TE3TL is an NPN digital transistor from the ROHM DTC143T series, housed in a surface-mount SOT-416 (EMT3) package. It integrates a single bias resistor with a nominal value of 4.7 kΩ to simplify circuit design. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Electrical characteristics include a minimum DC current gain of 100 at 1 mA and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, with an operating junction temperature range up to 150°C.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input components
- Thin-film resistor construction provides complete isolation for positive input biasing
- Simplified operation requiring only on/off condition settings
Applications
- Inverter circuits
- Interface logic
- Driver stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the exact package variant and taping specifications. Confirm RoHS compliance status and long-term supply availability directly with authorized distributors or the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a compact NPN digital switch with a 4.7 kΩ base resistor is required. Ensure the application operates within the 50 V collector-emitter voltage limit and 100 mA current threshold. Verify that the SOT-416 footprint matches the PCB layout constraints and that the 150 mW power dissipation rating is sufficient for the thermal environment.
Part Context
This part belongs to the DTC143T series of Bias Resistor Built-in Transistors (BRBTs). The series includes complementary PNP types (DTA143T) and various package options such as SOT-723, SOT-323, and SOT-346. The TE3 designation specifically identifies the SOT-416 package variant within this standardized family.
Replacement Considerations
Complementary PNP equivalents are available in the DTA143T series. Other packages in the same electrical family include DTC143TM (SOT-723), DTC143TUB (SOT-323FL), and DTC143TKA (SOT-346). Verify pinout compatibility and thermal performance when substituting.
