Overview
The DTC144EET1H is an NPN Bipolar Digital Transistor (BRT) manufactured by onsemi. It integrates a single NPN transistor with a monolithic bias network consisting of two resistors: a series base resistor and a base-emitter resistor. This integration eliminates the need for discrete components, simplifying circuit design and reducing board space. The device features a collector-emitter voltage (Vceo) of 50 V, a continuous collector current of 100 mA, and input resistance values (R1 and R2) of 47 kΩ each. It is housed in a SC-75 (SOT-416) surface-mount package with three leads. The component is AEC-Q101 qualified and supports PPAP capabilities.
Feature Summary
- Integrates NPN transistor with dual bias resistors to replace discrete components
- AEC-Q101 qualified for automotive reliability standards
- Supports PPAP capability for automotive supply chain requirements
- Halide-free material composition
Applications
- Industrial control systems
- Power management circuits
- Automotive electronic modules
Procurement Notes
Verify the specific suffix 'H' against the official onsemi datasheet to confirm pinout, marking, or electrical parameter variations compared to standard variants like 'T1G'. Ensure the source document explicitly lists DTC144EET1H as a distinct part number rather than a generic family designation. Confirm RoHS and halide-free status through the manufacturer's compliance documentation before procurement.
Selection Notes
Select this component when a compact NPN switching solution with integrated biasing is required for 50 V applications. The 47 kΩ internal resistor ratio suits direct logic interface scenarios without external pull-down networks. Verify that the SC-75 package dimensions fit the target PCB layout constraints. Ensure the 100 mA collector current rating exceeds the maximum load current in the intended switching application.
Part Context
This part belongs to the DTC144E series of digital transistors from onsemi. The series typically includes complementary PNP types such as the DTA144E. These devices are designed to simplify biasing networks in switching applications. The SC-75 package offers a small footprint suitable for high-density surface mount assemblies. The product line emphasizes automotive qualification and reliability for industrial use cases.
Replacement Considerations
Publicly confirmed substitute part numbers for DTC144EET1H were not found in the provided reference data. Cross-referencing with other manufacturers requires verifying identical electrical parameters, specifically the 50 V rating, 100 mA current, and 47 kΩ/47 kΩ resistor configuration.
