DTC014YMT2L

Overview

The DTC014YMT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SOT-723 (VMT3) surface-mount package. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a typical base resistor of 10 kOhms and an emitter-base resistor of 47 kOhms, yielding a resistance ratio of approximately 4.7. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The component supports operation up to a maximum junction temperature of +150°C.

Feature Summary

• Integrates NPN transistor with dual internal bias resistors for simplified circuit design
• Provides high-speed switching capability with a 250 MHz transition frequency
• Utilizes compact SOT-723 surface-mount packaging for space-constrained applications

Applications

• General-purpose digital switching circuits
• Interface driver stages in consumer electronics
• Logic level translation between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix MT2L against the manufacturer's official datasheet to confirm the exact taping specification and reel quantity. Ensure compatibility with standard SOT-723 footprints during PCB layout. Confirm RoHS compliance status through the latest production documentation before finalizing procurement orders.

Selection Notes

Select this component when a single NPN digital switch with a 10k/47k resistor network is required. Compare the 50V breakdown voltage and 100mA current limit against circuit demands. Consider the SOT-723 package dimensions if board space is limited relative to larger packages like SC-70 or SOT-23.

Part Context

This part belongs to the DTC014 series of pre-biased transistors from ROHM. It serves as the NPN counterpart to PNP variants such as the DTA014 series. The device is designed to replace discrete resistor-transistor combinations, reducing component count and assembly time in standard digital logic applications.

Replacement Considerations

Direct functional substitutes may include other NPN digital transistors with similar 50V ratings and 10k/47k resistor networks in SOT-723 packages, such as the DTC114YM or DTC124X series, provided pinout and electrical parameters match.
