Procurement Notes

Verify the specific ordering suffix to confirm packaging type and quantity. The base part number DTA124EUA indicates a standard tape-and-reel configuration. Confirm RoHS compliance status and ensure the supplier provides official datasheets matching the exact suffix. Check for automotive qualification if required for the target application environment.

Selection Notes

Select this component when a PNP digital transistor with 22kΩ/22kΩ resistor ratio is needed. Ensure the -50V voltage rating and -100mA current capacity meet circuit requirements. Compare against DTA124EU3 or DTA124EU3HZG for alternative packaging or automotive grades. Verify thermal management needs given the 200mW power dissipation limit in the small outline package.

Part Context

This part belongs to the DTA124 series of pre-biased transistors from ROHM. It shares pinout compatibility with variants like DTA124EU3 and DTA124XU3. The 'T106' suffix typically denotes the reel quantity and packing method. It is functionally similar to other PNP digital transistors but distinguished by its specific internal resistor values and package dimensions.

Replacement Considerations

DTA124EU3 and DTA124EU3HZG are confirmed substitutes with identical pinouts and packages. DTA124XU3 offers similar functionality but may have different resistor values. Verify that any replacement maintains the same polarity, voltage ratings, and thermal characteristics.
