Overview
The DTA115GKAT146 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device incorporates an internal resistor of 100 kΩ, facilitating simplified circuit design for inverter and interface applications. Packaged in the SOT-323 (UMT3) form factor, it supports surface mount technology with a maximum power dissipation of 200 mW at 25°C ambient temperature.
Feature Summary
- Built-in biasing resistors eliminate the need for external input components, enabling direct configuration of inverter circuits.
- Simplified operation requires only setting on/off conditions, reducing complexity in circuit design.
- High transition frequency supports efficient performance in high-speed switching applications.
Applications
- Inverter circuits
- Interface logic
- Driver stages
Procurement Notes
Verify the specific ordering suffix against official ROHM documentation to confirm packaging details such as reel size and tape width. Ensure compatibility with standard surface mount assembly processes and validate storage conditions to maintain solderability before use.
Selection Notes
Select this component for designs requiring a compact PNP digital transistor with integrated biasing. Consider the SOT-323 package constraints and the 100 kΩ internal resistance value when calculating base drive requirements. Verify thermal management capabilities given the 200 mW power dissipation limit.
Part Context
This part belongs to the DTA115 series of digital transistors from ROHM Semiconductor. It serves as a PNP counterpart to NPN variants like the DTC115GUA. The series is designed for general-purpose switching and logic inversion tasks in consumer and industrial electronics.
Replacement Considerations
Direct pin-compatible substitutes include other ROHM parts within the same series, such as DTA115GUA or DTA115GUAT106. Cross-manufacturer replacements require verification of electrical parameters and package dimensions.
