Overview
The DTA144WCAT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SST3 (SOT-23-3) surface-mount package. It supports a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a base resistor (R1) of 47 kOhms and an emitter-base resistor (R2) of 22 kOhms. Key electrical characteristics include a minimum DC current gain (hFE) of 56 at 5 mA and 5 V, a maximum transition frequency of 250 MHz, and a power dissipation rating of 200 mW. The component operates up to a maximum junction temperature of +150 C.
Feature Summary
- Integrates NPN/PNP bipolar transistor with internal biasing resistors to simplify circuit design
- Optimized for high-speed switching applications with a 250 MHz transition frequency
- Compact SOT-23-3 surface-mount packaging suitable for space-constrained designs
Applications
- General-purpose signal inversion circuits
- Driver circuits for logic interfaces
- Switching applications in consumer electronics
Procurement Notes
Verify the specific suffix CAT116 against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Ensure compatibility with RoHS3 standards if required by the target market regulations. Confirm availability through authorized distributors as lead times may vary based on production schedules.
Selection Notes
Select this component when a PNP configuration with a 47k/22k resistor ratio is required. Compare the 200 mW power dissipation limit against thermal requirements. Consider the 50 V voltage rating relative to the system supply voltage. Evaluate the 100 mA current capacity against load demands.
Part Context
This part belongs to the DTx series of digital transistors from ROHM Semiconductor. It is functionally similar to other parts in the DTA144 family but distinguished by the specific CAT116 tape-and-reel packaging designation. It serves as a pre-biased alternative to discrete resistor networks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with generic PNP digital transistors having identical R1/R2 values before substitution.
