DTA114YCAHE3-TP

Overview

The DTA114YCAHE3-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single PNP bipolar junction transistor with an internal base resistor of 10 kOhms in a surface-mount SOT-23 package. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Key electrical specifications include a minimum DC current gain (hFE) of 68 at -5 mA and -5 V, a transition frequency of 250 MHz, and a power dissipation rating of 200 mW. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates a PNP transistor with a 10 kOhm base resistor for simplified circuit design
• Automotive-grade reliability certified under the AEC-Q101 standard
• High-frequency performance capability up to 250 MHz transition frequency
• Compact SOT-23 surface-mount packaging for space-constrained applications

Applications

• Switching circuits in automotive electronic systems
• General-purpose digital logic interfacing
• Low-power signal switching applications

Procurement Notes

Verify component authenticity through authorized MCC distributors or verified supply chain channels. Confirm that the received parts match the DTA114YCAHE3-TP marking and package type. Check for AEC-Q101 certification documentation if automotive compliance is required. Ensure storage conditions maintain moisture sensitivity levels according to manufacturer guidelines prior to soldering.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required. The 10 kOhm internal resistor eliminates external base components. Verify that the -50 V voltage rating and -100 mA current capacity meet system requirements. Consider the SOT-23 footprint for PCB layout compatibility. Ensure thermal management supports the 200 mW power dissipation limit in the intended operating environment.

Part Context

This part belongs to the DTA114YCA series of pre-biased digital transistors from Micro Commercial Components. The suffix HE3 indicates specific manufacturing attributes, while TP denotes tape and reel packaging options. It serves as the PNP counterpart to the NPN DTC114YCAHE3-TP within the same product family, sharing similar electrical characteristics and package dimensions.

Replacement Considerations

The DTC114YCAHE3-TP is the NPN equivalent in the same series. For direct substitution, verify polarity requirements. Other manufacturers offer compatible PNP digital transistors with similar ratings, but pinout and electrical parameters must be cross-referenced against official datasheets before implementation.
