Overview
The DTC143TU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with a typical input resistance of 4.7 kOhms and a resistor ratio of 2.1. The device supports a supply voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 200 mW. Key electrical parameters include a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, a maximum operating frequency of 250 MHz, and a collector-emitter saturation voltage of 300 mV. It is qualified under AEC-Q101 standards for automotive applications.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input components.
- Qualified for automotive grade reliability under AEC-Q101 standards.
- Provides high-speed switching capabilities suitable for signal processing applications.
Applications
- Automotive electronic systems requiring high-reliability switching components.
- Inverter circuits where external biasing resistors are omitted.
- General-purpose signal processing and switching applications.
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the specific suffix matches the required packaging format. Ensure compliance with RoHS directives and AEC-Q101 automotive qualification requirements before integration into final assemblies.
Selection Notes
Select this component when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. Consider the 50 V voltage rating and 100 mA current capacity against load requirements. Verify thermal management needs given the 200 mW power dissipation limit in the SOT-323 package.
Part Context
This part belongs to the ROHM DTC143 series of digital transistors. It serves as the recommended replacement for the discontinued DTC143TUAFRA. The device shares pinout compatibility with other UMT3 packaged variants within the family, facilitating direct board-level upgrades.
Replacement Considerations
The DTC143TU3HZG is listed as a similar level replacement with the same pinout and package. Verify datasheet specifications for both parts to ensure electrical parameter alignment before substitution.
