DTC113ZMT2L

Overview

The DTC113ZMT2L is a single NPN pre-biased bipolar junction transistor manufactured by ROHM Semiconductor. It integrates bias resistors within the SOT-723 (VMT3) surface-mount package to simplify circuit design. Key electrical parameters include a collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 150 mW. The device features a typical input resistance of 1 kOhm with a resistor ratio of 10, ensuring a minimum DC current gain of 33 at 5 mA and 5 V. It supports a maximum operating frequency of 250 MHz and operates up to +150°C.

Feature Summary

• Integrates built-in bias resistors to eliminate external input components for inverter circuits
• Utilizes thin-film resistors for complete isolation and elimination of parasitic effects
• Simplifies circuit design by requiring only on/off condition settings

Applications

• Inverter circuits
• Switching applications
• General-purpose digital logic interfacing

Procurement Notes

Verify the specific suffix MT2L corresponds to the VMT3 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and lead-free characteristics against the latest manufacturer datasheet. Ensure the application environment does not require automotive qualification, as standard grades may lack AEC-Q101 certification. Cross-reference the part number with official ROHM documentation to confirm availability and production lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required. The 1 kOhm input resistance suits moderate drive levels, while the 50 V rating provides adequate headroom for low-voltage digital systems. Consider the 150 mW power dissipation limit for thermal management in dense PCB layouts. Verify that the 250 MHz frequency response meets the signal speed requirements of the target application.

Part Context

This device belongs to the DTC113Z series of digital transistors from ROHM Semiconductor. It is the NPN variant of a family that includes complementary PNP types such as the DTA113Z series. The series is characterized by its use of thin-film resistors for improved performance over discrete resistor implementations. The VMT3 package offers a small footprint suitable for space-constrained modern electronics designs.

Replacement Considerations

• DTA113Z series (complementary PNP type)
• DTC113ZE3HZGTL (different package)
• DTC113ZCAHZGT116 (different package)
