DTC014TMT2L

Overview

The DTC014TMT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device has a power dissipation rating of 150 mW and supports surface mount installation in an SC-105AA-3 (VMT3) package. Key electrical parameters include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a typical input resistance of 10 kOhms, and a maximum operating frequency of 250 MHz. The component is rated for a maximum operating temperature of +150°C.

Feature Summary

• Integrates NPN bipolar junction transistor with internal bias resistors to reduce external component count
• Provides high-speed switching capability suitable for interface and driver applications
• Offers compact surface-mount packaging for efficient PCB layout

Applications

• General-purpose digital switching circuits
• Interface drivers between logic levels
• Biasing networks for small-signal amplification

Procurement Notes

Verify the specific suffix 'TMT2L' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with standard SMD reflow profiles. Check for RoHS compliance status as indicated in official documentation. Confirm that the 50 V rating meets system voltage requirements under all transient conditions.

Selection Notes

Select this component when a compact NPN solution with integrated base biasing is required. The 10 kOhm input resistance provides a standard bias point for many logic families. Consider the 250 MHz frequency limit for high-speed applications. Compare hFE variations if precise gain control is necessary across different operating points.

Part Context

This part belongs to ROHM's DTC series of pre-biased transistors, designed to replace discrete resistor-transistor combinations. The DTC014 variant specifically denotes an NPN configuration with 10 kOhm base resistor. The TMT2L suffix indicates the specific SC-105AA-3 package and reel packaging format used for automated assembly.

Replacement Considerations

Direct substitutes may include other manufacturers' NPN digital transistors with similar 50 V ratings and 10 kOhm input resistance in SC-105AA or equivalent packages. Verify pinout compatibility and thermal characteristics before substitution.
