Overview
The DTA143XU3HZGT106 is a PNP digital transistor with built-in resistors, manufactured by ROHM Semiconductor. It operates with a supply voltage of -50 V and a continuous collector current of -100 mA. The device features an input resistance (R1) of 4.7 kΩ and an emitter-base resistance (R2) of 10 kΩ. Key electrical parameters include a DC current gain (hFE) of 33 to 33 at -10 mA and -5 V, a maximum operating frequency of 250 MHz, and power dissipation of 200 mW. It is housed in a SOT-323 (UMT3) package and meets AEC-Q101 automotive standards.
Feature Summary
- Built-in biasing resistors simplify circuit design by eliminating the need for external input resistors.
- AEC-Q101 qualified for high reliability in automotive applications.
- Compact SOT-323 surface-mount package suitable for space-constrained designs.
Applications
- Automotive electronic circuits requiring pre-biased switching
- Inverter circuits without external input resistors
- General-purpose digital switching in consumer electronics
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and AEC-Q101 certification status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain device integrity during assembly processes.
Selection Notes
Select this component for applications requiring a PNP digital transistor with integrated biasing resistors. The 4.7 kΩ input resistor value suits standard logic interface levels. Consider the complementary NPN type DTC143XU3HZG for paired configurations. Verify thermal management capabilities given the 200 mW power dissipation limit in the SOT-323 package.
Part Context
This part belongs to the DTA143 series of digital transistors from ROHM Semiconductor. It is designed as a replacement for older variants like DTA143XUA, which are no longer recommended for new designs. The UMT3 package variant offers improved mechanical stability compared to previous generations while maintaining pin compatibility.
Replacement Considerations
DTA143XU3HZG is a compatible alternative within the same family. DTC143XU3HZGT106 serves as the complementary NPN counterpart. Verify pinout and electrical specifications match before substitution in existing designs.
