Overview
The DTC143XUBHZGTL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416FL (UMT3F) surface-mount package. It integrates a bias resistor network with a typical input resistance of 4.7 kOhms and an emitter-base resistance of 10 kOhms. The device supports a collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 200 mW. It operates up to a maximum frequency of 250 MHz and withstands temperatures up to +150°C. This component is designated as Not Recommended for New Designs.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Automotive-grade reliability compliant with AEC-Q101 standards.
- Compact SOT-416FL package suitable for space-constrained applications.
Applications
- Inverter interface circuits
- Driver logic stages
- General-purpose digital switching
Procurement Notes
Verify end-of-life status before integration, as this part is not recommended for new designs. Confirm availability through authorized distributors for existing production runs. Ensure supply chain stability due to potential discontinuation risks associated with legacy components.
Selection Notes
Select the DTC143XU3HZGT106 as a direct replacement for new designs. Both parts share identical electrical specifications including 50V voltage, 100mA current, and 4.7kOhm input resistance. Verify package compatibility between UMT3F and UMT3 if mechanical constraints are strict.
Part Context
This component belongs to the DTC143 series of pre-biased transistors from ROHM Semiconductor. These devices combine NPN transistors with internal resistors to provide convenient digital switching solutions. The specific model utilizes the UMT3F package variant, offering a compact footprint for modern electronics.
Replacement Considerations
The DTC143XU3HZGT106 is listed as a recommended alternative with similar specifications. Verify pinout and package dimensions (SOT-323 vs SOT-416FL) during PCB layout updates.
