DTC114EKA-TP

Overview

The DTC114EKA-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates an NPN bipolar junction transistor with internal biasing resistors in a compact SOT-23-3L surface-mount package. Key electrical specifications include a collector continuous current of 100 mA, a power dissipation rating of 200 mW, and a maximum operating temperature of +150°C. The device features a typical input resistance of 10 kOhms with a resistor ratio of 1. The saturation voltage is specified at 300 mV. This component is designed for high-density circuit applications requiring simplified biasing networks.

Feature Summary

• Integrates NPN transistor with built-in biasing resistors to reduce external component count
• Designed for surface-mount assembly using the standard SOT-23-3L footprint
• Supports high thermal stability with a maximum junction temperature of +150°C

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Biasing networks in portable electronic devices

Procurement Notes

Verify the complete part number including the -TP suffix to ensure correct packaging configuration. Confirm RoHS compliance status through the official datasheet or manufacturer notification. Cross-reference the Mouser part number 833-DTC114EKA-TP for accurate sourcing details. Ensure compatibility with automated pick-and-place equipment due to the small SOT-23-3L form factor.

Selection Notes

Select this component when a single NPN switch with integrated base biasing is required. The 10 kOhm input resistance suits direct interfacing with standard logic outputs. Consider the 200 mW power dissipation limit for thermal management in dense PCB layouts. Compare against PNP variants like DTA114EKA-TP if complementary polarity is needed.

Part Context

This part belongs to the DTC114 series of pre-biased transistors from MCC. It shares the same internal circuit topology as other members but differs in packaging and specific electrical tolerances. The EKA suffix typically denotes the SOT-23-3L package variant within the broader DTC114 family.

Replacement Considerations

Direct substitutes include DTC114ECA-TP and DTC114EUA-TP, which offer similar NPN functionality. Verify pinout compatibility and exact resistance values before substitution. Check datasheets for differences in hFE gain and saturation voltage characteristics.
