Overview
The DTC143XUAT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates biasing resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device features a typical input resistance of 22kΩ and an emitter-base resistance of 47kΩ. It operates with a maximum power dissipation of 200mW and supports junction temperatures up to +150°C. The component is qualified under AEC-Q101 standards for automotive applications.
Feature Summary
- Integrates built-in biasing resistors to eliminate the need for external input components, enabling straightforward inverter circuit configuration.
- Designed for high-speed switching operations with a transition frequency capability of 250 MHz.
- Complies with AEC-Q101 qualification standards, ensuring reliability for automotive electronic environments.
Applications
- Automotive control circuits requiring AEC-Q101 compliant switching components.
- General-purpose inverter circuits where simplified biasing is required.
- Low-voltage signal switching applications within consumer electronics.
Procurement Notes
Verify the specific ordering suffix to confirm the tape-and-reel packaging quantity and variant details. Ensure the procurement channel provides official documentation confirming AEC-Q101 automotive qualification status. Cross-reference the manufacturer part number against the latest datasheet to confirm current production status and availability constraints.
Selection Notes
Select this component when a single NPN digital transistor with a 22kΩ base resistor is required in an SOT-323 package. Compare the 100mA collector current and 50V breakdown voltage against circuit load requirements. Consider the 200mW power dissipation limit and thermal management needs for the intended operating environment.
Part Context
This part belongs to the ROHM DTC143X series of pre-biased transistors. It shares the same functional architecture as other variants in the family but differs in internal resistor values and packaging suffixes. The 'UAT' suffix typically denotes specific packaging or grading configurations within the broader DTC143 product line.
Replacement Considerations
The DTC143XU3HZGT106 serves as a verified alternative with identical pinout and package. Note that the replacement features different internal resistor values (4.7kΩ input vs. 22kΩ), which may require circuit redesign. Verify compatibility before substitution.
