DTC014EMT2L

Overview

The DTC014EMT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates in an SOT-723-3 surface-mount package with a maximum collector-emitter voltage of 50 V and continuous collector current of 100 mA. The device includes typical input resistance (R1) and emitter-base resistance (R2) values of 10 kOhms each, maintaining a resistor ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 35 at 5 mA and 10 V, a transition frequency up to 250 MHz, and power dissipation capability of 150 mW. The component supports operation up to +150°C junction temperature.

Feature Summary

• Integrates dual bias resistors to eliminate external components and simplify inverter circuit configuration.
• Provides high-speed switching performance suitable for interface and driver applications.
• Offers compact surface-mount packaging for efficient board space utilization.

Applications

• Inverter circuits requiring simple on/off control logic.
• Interface drivers between microcontrollers and peripheral devices.
• General-purpose switching applications in consumer electronics.

Procurement Notes

Verify the specific suffix EM-T2L against official ROHM documentation to confirm package type and reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a single NPN digital transistor with equal bias resistors (10kΩ/10kΩ) is required. Consider the 50V voltage rating and 100mA current capacity against load requirements. Evaluate the SOT-723 footprint constraints against available PCB real estate compared to alternative packages like UMT3F.

Part Context

This part belongs to the DTC014 series of digital transistors from ROHM Semiconductor. The series offers complementary PNP variants such as the DTA014 series. These components are standard-grade products designed for general-purpose use, distinct from automotive-grade qualified parts which carry different suffixes or model designations.

Replacement Considerations

Direct functional substitutes within the same family include other DTC014 variants with different resistor ratios or packages, such as DTC014YEBTL. Verify pinout compatibility and electrical ratings before substituting with generic NPN pre-biased transistors from other manufacturers.
