DTA114YCA-HF

Overview

The DTA114YCA-HF is a PNP digital transistor manufactured by Comchip Technology, designed for surface-mount applications in the SOT-23 package. It integrates built-in biasing resistors to simplify circuit design by eliminating external components. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance (R1) of 10 kOhms and an emitter-base resistance (R2) of 47 kOhms, resulting in a typical resistor ratio of 4.7. Power dissipation is rated at 150 mW, with an operating temperature range from -55°C to +150°C.

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Confirm that the specific ordering suffix corresponds to the required packaging format, such as cut tape or reel quantities. Ensure the component meets all relevant environmental standards for the intended deployment region.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The 10 kOhm input resistance offers a standard drive interface. Verify that the -50 V voltage rating and -100 mA current capacity align with the load requirements. Consider the SOT-23 footprint constraints during PCB layout planning.

Part Context

This part belongs to the DTA series of digital transistors from Comchip Technology, which are characterized by internal resistor networks. These devices serve as direct replacements for discrete transistor-resistor combinations, reducing board space and assembly complexity. The 'HF' suffix typically indicates Halogen-Free manufacturing processes compliant with environmental directives.

Replacement Considerations

Direct substitutes may include other PNP digital transistors with similar VCEO ratings and integrated resistor values. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with manufacturers like ROHM or ON Semiconductor for equivalent SOT-23 packaged parts with comparable R1/R2 ratios.
