DTC114TUA-TP

Overview

The DTC114TUA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-323 surface-mount package. It integrates thin-film bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW at 25°C. The device features a typical input resistance of 10 kΩ, a DC current gain of 300, and a transition frequency of 250 MHz. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without external input resistors
• Thin-film resistors provide complete isolation allowing negative input biasing
• Eliminates parasitic effects for simplified on/off operation

Applications

• Inverter circuits
• Switching applications requiring simplified bias networks
• General-purpose digital logic interfacing

Procurement Notes

Verify the component authenticity through authorized MCC distributors or direct channels. Confirm the RoHS compliance status indicated by the suffix 'P' if required by specific environmental regulations. Ensure the ordering information matches the tape and reel packing specification of 3000 pieces per reel as documented in the official datasheet.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. The SOT-323 package offers a small footprint suitable for high-density PCB layouts. Consider the 50 V collector-emitter voltage rating and 100 mA current capability to ensure adequate headroom for the intended switching loads.

Part Context

This part belongs to the DTC114 series of digital transistors from Micro Commercial Components. The series typically includes various resistor configurations and packages. The DTC114TUA specifically denotes the NPN type with a 10 kΩ base resistor in the SOT-323 package, distinguishing it from other variants like the DTC114TE or DTC114EKA which may differ in package or internal resistance values.

Replacement Considerations

Compatible substitutes include other NPN digital transistors with similar 50 V ratings and SOT-323 packaging, such as the DTC114YCAHE3-TP or DTC114EKA-TP. Verify that the replacement maintains the 10 kΩ input resistance and comparable hFE characteristics to ensure circuit compatibility.
