DTC144TMT2L

Overview

The DTC144TMT2L is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in a SOT-723-3 surface-mount package. It supports a collector-emitter voltage (Vceo) of 50 V and a continuous collector current of 100 mA. The device offers a minimum DC current gain (hFE) of 100 at Ic=1 mA and Vce=5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, and the junction temperature range extends up to +150°C.

Feature Summary

• Integrates NPN bipolar junction transistor with built-in potential divider bias resistors for simplified circuit design
• Optimized for high-speed switching applications with a transition frequency of 250 MHz
• Compact SOT-723-3 surface-mount package suitable for space-constrained PCB layouts

Applications

• General-purpose signal switching in consumer electronics
• Driver circuits for low-power loads in industrial control systems
• Logic level translation interfaces in embedded microcontroller systems

Procurement Notes

Verify the specific suffix 'T2L' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications and quantity per reel. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance documentation corresponding to the production batch. Cross-reference the Mouser part number 755-DTC144TMT2L for accurate distributor-specific handling instructions.

Selection Notes

Select this component when a compact NPN switch with integrated base resistance is required for 50 V applications. The 100 mA current rating and 250 MHz frequency make it suitable for moderate-speed digital logic interfacing. Compare against similar series parts like DTC144TUAT106 if different packaging or slightly higher power dissipation ratings are needed for the target application.

Part Context

This part belongs to ROHM's DTC144 series of pre-biased transistors, designed to replace discrete resistor-transistor networks. The T2L suffix typically indicates a specific tape-and-reel packaging format compatible with automated assembly equipment. It serves as a direct replacement for older discrete configurations while reducing board space and assembly costs.

Replacement Considerations

Direct substitutes include DTC144TUAT106 (SOT-323-3 package) and DTC144EMFHAT2L (SOT-723-3 package). Verify pinout compatibility and thermal characteristics when swapping packages. Ensure the alternative part maintains the 50 V Vceo and 100 mA Ic ratings for equivalent performance.
