DTA115ECA-TP

Overview

The DTA115ECA-TP is a pre-biased PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-23 package. It integrates a single NPN transistor with internal biasing resistors R1 and R2, featuring nominal values of 100 kΩ and a resistance ratio of 1.0. Key electrical specifications include a maximum supply voltage (Vcc) of -50 V, a collector current (Ic) of -100 mA, and a power dissipation (Pd) of 200 mW at 25°C. The device operates within a junction temperature range of -55°C to +150°C and offers a transition frequency (fT) of 200 MHz.

Feature Summary

• Integrates a single PNP transistor with built-in base and emitter resistors for simplified circuit design.
• Halogen-free 'Green' device compliant with RoHS standards and UL 94V-0 flammability rating.
• Moisture sensitivity level 1 classification suitable for standard surface mount assembly processes.

Applications

• General-purpose switching applications requiring compact footprint.
• Driver circuits for logic interfaces and signal level translation.
• High-frequency switching operations up to the specified transition frequency.

Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unverified sources lack traceability and quality assurance guarantees. Confirm that the ordering suffix '-TP' corresponds to the specific RoHS-compliant tape and reel packaging configuration required for your manufacturing line before finalizing orders.

Selection Notes

Select this component when a PNP digital transistor with a 100 kΩ input resistor and unity resistance ratio is required. Ensure the application voltage does not exceed the -50 V maximum rating and that thermal management accommodates the 200 mW power dissipation limit. Verify that the SOT-23 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the DTA115ECA series of pre-biased transistors from Micro Commercial Components. It is designed as a drop-in replacement for discrete resistor-transistor networks, reducing board space and assembly costs. The ECA suffix typically denotes the specific pinout and internal resistor configuration standardized for the SOT-23 package family.

Replacement Considerations

Cross-reference with other manufacturers offering PNP digital transistors in SOT-23 packages with similar 100 kΩ input resistance and -50 V ratings. Verify pin compatibility and electrical parameter equivalence, particularly regarding saturation voltage and current gain, before substituting.
