DTC143XUBTL

Overview

The DTC143XUBTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device includes a 4.7kΩ input resistor (R1) and a 10kΩ emitter-base resistor (R2), resulting in a resistance ratio of approximately 2.1. Packaged in the UMT3F (SOT-323FL) surface-mount format, it supports a maximum power dissipation of 200mW and functions up to a transition frequency of 250MHz. The component is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

Integrated biasing resistors eliminate the need for external components, enabling straightforward inverter circuit configuration.
Automotive-grade qualification ensures reliability for use in vehicle electronic systems.
Compact SMD package facilitates high-density PCB layout and automated assembly.

Applications

Automotive digital logic circuits
General-purpose switching applications
Inverter circuits requiring minimal external components

Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing BOM requirements regarding automotive qualification status and RoHS compliance before finalizing procurement decisions.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. Consider the 50V rating and 100mA current capacity for low-power switching tasks. Verify that the UMT3F package dimensions align with the target PCB footprint constraints.

Part Context

This part belongs to the DTC143 series of pre-biased transistors from ROHM Semiconductor. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. The series offers various packages and resistance values to suit different application needs.

Replacement Considerations

DTC143XU3HZGT106 and DTC143XU3T106 are listed as recommended replacements with similar specifications. Verify pinout compatibility and electrical parameters before substitution.
