Overview
The DTC143XEBTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a typical base resistor (R1) of 1 kOhm and an emitter-base resistor (R2) of 47 kOhm. Key electrical parameters include a minimum DC current gain (hFE) of 68 at 10 mA and 5 V, a maximum transition frequency of 250 MHz, and a power dissipation rating of 150 mW. It is housed in the EMT3F (SOT-416FL) surface-mount package.
Feature Summary
- Integrates bias resistors to eliminate external input components for inverter circuits
- Provides simplified on/off control logic through pre-biased internal structure
- Supports high-speed switching applications with a 250 MHz transition frequency
Applications
- Inverter circuits requiring minimal external component count
- General-purpose switching applications in consumer electronics
- Interface circuits between microcontrollers and load devices
Procurement Notes
Verify the specific suffix EBTL against official ROHM documentation to confirm the EMT3F package type and resistor values. Ensure compliance with RoHS directives as indicated in manufacturer specifications. Confirm that the application does not involve automotive equipment, as standard-grade products may lack required reliability certifications for such environments.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for low-power switching. The 1 kOhm base resistor suits applications needing moderate drive currents. Compare against complementary PNP types like the DTA124X series if push-pull configurations are necessary. Verify thermal management requirements given the 150 mW power dissipation limit in the small SOT-416FL package.
Part Context
This part belongs to the ROHM DTC143 series of digital transistors, which are designed to replace discrete resistor-transistor combinations. The series offers various resistor ratios and packages to accommodate different circuit impedance and space constraints. The DTC143XEBTL specifically utilizes the EMT3F package, providing a balance between thermal performance and footprint size for surface-mount assembly processes.
