DTC044TMT2L

Overview

The DTC044TMT2L is an NPN digital transistor from ROHM Semiconductor, integrating a single transistor with built-in bias resistors in a compact SMD package. It features a typical input resistance of 47 kOhms and a resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a power dissipation of 150 mW, and a maximum operating frequency of 250 MHz. It operates within a temperature range of -55°C to +150°C and utilizes the SOT-723 (SC-105AA) package.

Feature Summary

• Integrates NPN transistor with built-in bias resistors for simplified circuit design
• High-speed operation capability up to 250 MHz
• Compact surface-mount packaging suitable for space-constrained applications

Applications

• General-purpose switching circuits
• Driver circuits for logic interfaces
• Level shifting applications

Procurement Notes

Verify the specific suffix TMT2L against official ROHM documentation to confirm tape-and-reel quantity and handling specifications. Ensure compatibility with standard SMT assembly processes for the SOT-723 package. Cross-reference RoHS compliance status directly with the manufacturer's latest certification documents prior to procurement.

Selection Notes

Select this component when a single NPN digital transistor with a 47 kOhm base resistor is required. Compare the 150 mW power dissipation and 50 V voltage rating against application demands. Consider the SOT-723 footprint constraints relative to alternative packages like SOT-23 or SC-70 if board space is limited.

Part Context

This part belongs to the DTC044 series of digital transistors manufactured by ROHM Semiconductor. These devices are designed to replace discrete resistor-transistor networks, reducing component count and PCB area. The series offers various resistor combinations and package options to suit different electronic design requirements.

Replacement Considerations

Check ROHM's official substitution list for equivalent parts within the DTC044 family. Verify pinout compatibility and electrical parameter equivalence before replacing with components from other manufacturers.
