DTA114YCA-TP

Overview

The DTA114YCA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-23 surface-mount package. It integrates thin-film bias resistors to enable inverter circuit configuration without external input components. Key electrical specifications include a maximum supply voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 200 mW. The device features a typical transition frequency of 250 MHz and a minimum DC current gain of 68. Internal resistance values consist of R1 at 10 kΩ and a resistance ratio (R2/R1) of 4.7.

Feature Summary

• Built-in thin-film bias resistors allow for inverter circuit configuration without connecting external input resistors
• Resistors provide complete isolation to permit negative biasing of the input and eliminate parasitic effects
• Simplified device design requiring only On/Off conditions to be set for operation

Applications

• Inverter circuits
• Logic buffer applications
• Switching circuits

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit parts. Ensure the ordering suffix matches the required packaging format, as the standard -TP designation indicates Tape & Reel packing with 3000 pieces per reel. Confirm RoHS compliance status based on specific suffix requirements before finalizing procurement orders.

Selection Notes

Select this component when a PNP pre-biased transistor with integrated biasing is required for space-constrained designs. Verify that the -50 V supply voltage and -100 mA current limits align with the target application parameters. Consider the SOT-23 package dimensions and thermal derating characteristics for proper heat management in the final assembly.

Part Context

This part belongs to the DTA114 series of PNP digital transistors from Micro Commercial Components. It is designed as a single NPN/PNP unit with built-in resistors to simplify circuit layouts. The device serves as a replacement for discrete resistor-transistor combinations, reducing board space and assembly complexity while maintaining consistent electrical performance across operating temperatures.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-23 package having similar -50 V ratings and 10 kΩ internal base resistance. Verify pinout compatibility and electrical parameter overlaps before substitution.
