DTC363EUT106

Overview

The DTC363EUT106 is an NPN digital transistor with built-in resistors, manufactured by ROHM Semiconductor. It features a UMT3 (SC-70) surface-mount package and supports a supply voltage of up to 20V. The device handles a continuous collector current of 600mA with a power dissipation rating of 200mW. Key electrical characteristics include a typical output voltage on-state of 40mV at 50mA/2.5mA input ratio, an input resistance of 4.7kΩ, and a DC current gain ranging from 70 to 200.

Feature Summary

• Low on-state output voltage optimized for muting circuits
• Capable of handling high collector currents up to 600mA
• Integrated biasing resistors reduce component count

Applications

• Muting circuits in audio equipment
• Switching applications requiring low saturation voltage
• General-purpose digital logic interfacing

Procurement Notes

Verify the specific suffix T106 corresponds to the UMT3 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design reviews account for the absolute maximum ratings regarding junction temperature and power dissipation limits during operation.

Selection Notes

Select this component when low saturation voltage is critical for signal integrity or efficiency. The 600mA current capability distinguishes it from standard low-current digital transistors. Verify that the SC-70 footprint aligns with the PCB layout constraints and thermal management requirements for the intended application environment.

Part Context

This part belongs to the DTC363E series, which includes variants like DTC363EK and DTC363ES offering different package options such as SMT3 and SPT. The EU designation specifically denotes the UMT3 package type. These devices are designed for general electronic equipment rather than automotive or high-reliability safety-critical systems without prior consultation.

Replacement Considerations

Direct pin-compatible substitutes within the same family include DTC363EU and other suffixes if package compatibility allows. Cross-brand replacements require verification of matching VCEO, IC, R1 values, and package dimensions.
