Overview
The DTA143XUAT106 is a single PNP 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 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 features a minimum DC current gain (hFE) of 30 at -10 mA and -5 V, operating up to a maximum frequency of 250 MHz and temperatures of +150 C. This component is designated as Not Recommended for New Designs.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input components.
- Enables straightforward configuration of inverter circuits where only on/off conditions require setting.
Applications
- Inverter circuits
- Driver circuits for relays and solenoids
- Switching applications in consumer electronics
Procurement Notes
Verify the obsolete status before procurement, as this part is marked Not Recommended for New Designs. Confirm availability through authorized distributors, noting that stock may be limited or discontinued. Ensure the ordering suffix matches the required reel quantity of 3000 units. Cross-reference with recommended replacement parts like DTA143XU3HZGT106 if long-term supply is required.
Selection Notes
Select this component for legacy designs requiring a PNP digital transistor with 4.7 kOhm input resistance in an SOT-323 package. Verify compatibility with existing board layouts due to the UMT3 form factor. Consider the -50V voltage rating and -100mA current limit for load requirements. Evaluate alternative recommended parts if new production is planned.
Part Context
This part belongs to the DTA143XUA series of PNP digital transistors from ROHM Semiconductor. It shares pinout and package dimensions with the DTA143XU3 and DTA143XU3HZG variants. While functionally similar, the DTA143XUAT106 is explicitly listed as obsolete, whereas its counterparts remain recommended for new designs.
Replacement Considerations
DTA143XU3HZGT106 and DTA143XU3T106 are confirmed replacements with identical pinouts and packages. These alternatives are recommended for new designs and offer better supply stability while maintaining electrical compatibility.
