Overview
The DTA124XETL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a supply voltage of -50V and supports a continuous collector current of -100mA. The device incorporates an input resistor (R1) of 22kΩ and an emitter-base resistor (R2) of 47kΩ. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at -5V and -5mA, a transition frequency of 250MHz, and a maximum power dissipation of 150mW. Packaged in the compact SOT-323 (UMT3) format, it is designed for surface mount applications.
Feature Summary
- Integrated bias resistors eliminate the need for external components, enabling straightforward inverter circuit configuration.
- Compact SOT-323 package facilitates high-density PCB layouts.
- High-speed switching capability supported by a 250MHz transition frequency.
Applications
- Inverter circuits
- Interface drivers
- General-purpose switching applications
Procurement Notes
Verify the specific suffix 'TL' against official ROHM documentation to confirm tape-and-reel packaging details and exact marking codes. Ensure compatibility with standard SMT assembly processes for the SOT-323 footprint. Cross-reference the part number with authorized distributors to confirm current availability status and lead times.
Selection Notes
Select this component for designs requiring a PNP digital transistor with a -50V rating and -100mA current capacity. The fixed 22kΩ/47kΩ resistor ratio suits standard logic interface levels. Consider the SOT-323 size constraints and thermal dissipation limits when evaluating alternative packages like SOT-723 or SOT-416 for different space or power requirements.
Part Context
This part belongs to the DTA124 series of pre-biased transistors from ROHM. It serves as the PNP counterpart to the NPN DTC124 series. The series is widely used in automotive and industrial electronics where space-saving and simplified biasing are critical. The DTA124XETL specifically utilizes the UMT3/SOT-323 package variant within this family.
Replacement Considerations
Direct pin-compatible substitutes include the DTA124XEFRATL (SOT-416/EMT3 package) and DTA124XMHZGT2L (SOT-723 package). Verify that the replacement package fits the PCB footprint and that electrical parameters such as VCEO and hFE meet the design specifications.
