Overview
The DTC115TUAT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 surface-mount package. It features a built-in 100 kOhm input resistor with a typical resistance ratio of 1. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a minimum DC current gain (hfe) of 100 at -1 mA and -5 V, a maximum operating frequency of 250 MHz, and power dissipation of 350 mW. The emitter-base voltage (VEBO) is rated at -5 V, with a maximum operating temperature of +150 C.
Feature Summary
- Integrates a bias resistor directly with the PNP transistor to simplify circuit design.
- Provides high-speed switching capabilities suitable for interface applications.
- Offers robust thermal performance with a maximum junction temperature of +150 C.
Applications
- Interface circuits between logic gates and loads
- Driver stages for relays or small motors
- Switching applications in consumer electronics
Procurement Notes
Verify the specific suffix AT106 to confirm the tape-and-reel packaging configuration and quantity per reel. Confirm RoHS compliance status through the official datasheet as indicated in distributor listings. Check the lifecycle status to ensure availability for new designs, as some variants may be marked as not recommended for new use.
Selection Notes
Select this component when a PNP digital transistor with a 100 kOhm base resistor is required in an SOT-323-3 package. Ensure the application voltage does not exceed -50 V and current requirements stay within -100 mA. Compare against NPN equivalents like the DTC115EUAT106 if polarity reversal is needed.
Part Context
This part belongs to the DTA115TUA series of Bias Resistor Built-in Transistors (BRBTs). It is designed to replace discrete resistor-transistor combinations, saving board space and assembly time. The SOT-323-3 package allows for compact layout in portable devices.
Replacement Considerations
Direct substitutes include other PNP BRBTs with similar electrical characteristics and pinouts, such as the DTA115TUA from other manufacturers. Verify package compatibility and electrical ratings before substitution.
