DTC114TE-TP

Overview

The DTC114TE-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-523 surface-mount package. It integrates a single internal bias resistor with a typical value of 10 kΩ, eliminating the need for external input components. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at IC=1mA and VCE=5V, and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 150 mW, with an operating temperature range from -55°C to +150°C.

Feature Summary

• Built-in thin-film bias resistors enable direct configuration of inverter circuits without external input resistors.
• Complete isolation of bias resistors allows negative biasing of the input while minimizing parasitic effects.
• Simplified design process where only On/Off conditions require setting for operation.

Applications

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

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or their authorized distributors listed on the official website. MCC explicitly warns against unauthorized sources due to counterfeiting risks. Ensure the ordering suffix 'TP' corresponds to the Tape & Reel packaging format containing 3,000 pieces per reel as specified in the manufacturer's documentation.

Selection Notes

Select this component when a compact NPN digital transistor with a 10 kΩ base resistor is required in a SOT-523 footprint. It is suitable for designs needing a transition frequency up to 250 MHz and a collector current limit of 100 mA. Consider the 150 mW power dissipation rating and the specific hFE range of 100 to 600 when designing for consistent gain performance across varying temperatures.

Part Context

This part belongs to the DTC114TE series of pre-biased transistors from Micro Commercial Components. It is specifically designed to replace discrete resistor-transistor combinations in space-constrained PCB layouts. The 'TP' suffix indicates RoHS compliance and tape-and-reel packaging, distinguishing it from bulk or cut-tape variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult the manufacturer's datasheet for cross-reference information or verify pin-compatible alternatives that match the SOT-523 package and electrical specifications.

FAQ
