Overview
The DTC144TKA-TP is a digital transistor manufactured by Micro Commercial Components (MCC). It belongs to the DTC144 series and is classified as a pre-biased NPN transistor. The component integrates an internal base resistor, specified as R1 only, with a resistance value of 47 kOhms. It features a maximum collector-emitter breakdown voltage (VCEO) of 50 V and a continuous collector current (Ic) rating of 100 mA. The device is designed for surface mount installation in SOT-323 packages. Its transition frequency is rated at 250 MHz, and it supports a maximum power dissipation of 200 mW. The part is currently listed as obsolete or discontinued.
Feature Summary
- Integrates a single 47 kOhm base resistor for simplified circuit design
- NPN pre-biased configuration for direct logic interface compatibility
- High-speed switching capability with 250 MHz transition frequency
Applications
- General-purpose switching applications
- Driver circuits for low-current loads
- Logic level translation interfaces
Procurement Notes
Verify end-of-life status before integration. Confirm availability through authorized distributors or secondary markets. Check RoHS compliance documentation for specific manufacturing dates. Ensure storage conditions meet moisture sensitivity level requirements if handling from non-sealed packaging. Validate pinout alignment with target PCB footprint.
Selection Notes
Compare against active alternatives within the DTC144 family if long-term supply is required. Evaluate package compatibility between SOT-323 and potential replacements like SOT-523. Consider thermal performance differences if operating near maximum power dissipation limits. Verify internal resistor tolerance specifications against circuit biasing requirements.
Part Context
This component is part of the broader DTC144 series of pre-biased transistors from MCC. Variants such as DTC144TE-TP and DTC144TUA-TP share similar electrical characteristics but differ in package types and internal resistor configurations. The TKA suffix typically denotes specific internal resistance values and package styles within this product line.
Replacement Considerations
DTC144TUA-TP offers identical electrical parameters in an SOT-323 package. DTC144TE-TP provides similar functionality in a smaller SOT-523 package. Verify pinout compatibility when substituting with these active parts.
