DTC123YE-TP

Overview

The DTC123YE-TP is an NPN digital transistor with a pre-biased resistor, manufactured by Micro Commercial Components (MCC). It is housed in a surface-mount SOT-523 package. Key electrical specifications include a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a typical DC current gain of 33 at 10 mA and 5 V, with a maximum saturation voltage of 300 mV at 500 µA base current and 10 mA collector current. It incorporates a single internal base resistor (R1) of 2.2 kOhms. The component supports a transition frequency of 200 MHz and has a maximum power dissipation of 150 mW.

Feature Summary

• Integrated pre-biasing circuitry simplifies interface design for logic signals
• Halogen-free green device compliant with RoHS standards
• Moisture sensitivity level 1 rating for reliable handling
• Epoxy meets UL 94V-0 flammability rating

Applications

• General-purpose switching applications
• Driver circuits for relays and solenoids
• Logic level translation between microcontrollers and peripheral devices

Procurement Notes

Verify the authenticity of the DTC123YE-TP by purchasing only from authorized MCC distributors or directly from Micro Commercial Components Corp. Ensure the ordering suffix -TP corresponds to tape and reel packaging as specified in the official documentation. Confirm that the received components meet the manufacturer's quality standards for handling and storage to maintain traceability and warranty coverage.

Selection Notes

Select the DTC123YE-TP when an NPN configuration with a 2.2 kOhm base resistor is required within a compact SOT-523 footprint. Consider this component for designs needing a 50 V collector-emitter breakdown and 100 mA current capacity. Verify that the thermal resistance of 150°C/W and junction temperature range of -55°C to +150°C align with the specific ambient operating conditions of the target application.

Part Context

This component belongs to the DTC123 series of digital transistors produced by Micro Commercial Components. It is part of a family of pre-biased BJT devices designed to replace discrete resistor-transistor networks. The SOT-523 package offers a small form factor suitable for space-constrained printed circuit board layouts in consumer electronics and industrial control systems.

Replacement Considerations

Consult official MCC datasheets for cross-reference data. Potential substitutes may include other NPN digital transistors with similar 50 V ratings and 2.2 kOhm base resistors in SOT-523 packages, such as variants from other manufacturers like ROHM or ON Semiconductor, provided pinouts and electrical characteristics match.
