Overview
The DTA114EETL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors in an SMD/SMT configuration. It operates with a supply voltage of -50V and supports a continuous collector current of -100mA. The device incorporates two internal resistors: an input resistance (R1) of 10 kOhms and an emitter-base resistance (R2) of 10 kOhms. Key electrical parameters include a DC current gain (hFE) of at least 30 and a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, with a storage temperature range from -55°C to +150°C.
Feature Summary
- Integrates dual biasing resistors to simplify circuit design by eliminating external components.
- Provides high-speed switching capabilities suitable for interface and driver applications.
- Utilizes a compact surface-mount package for efficient board space utilization.
Applications
- Inverter circuits
- Interface logic drivers
- General-purpose switching applications
Procurement Notes
Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure that the component meets RoHS compliance requirements for the intended manufacturing process. Confirm that the application environment remains within the specified thermal limits to maintain reliability.
Selection Notes
Select this component when a PNP digital transistor with equal biasing resistors is required for signal inversion or level shifting. Compare the 10kΩ resistor values against alternative models if different drive currents are needed. Verify that the -50V rating aligns with the system's power supply constraints.
Part Context
This part belongs to the DTA114 series of digital transistors from ROHM Semiconductor. It is designed as a standard discrete solution for replacing multiple discrete components with a single integrated device. The series offers various resistor configurations to suit different logic families and driving requirements.
Replacement Considerations
Check for direct replacements such as the DTA114EE3TL, which shares similar specifications and packaging. Ensure that any substitute maintains the same polarity, resistor ratios, and thermal characteristics to guarantee functional equivalence.
