DTC363TKT146

Overview

The DTC363TKT146 is an NPN digital transistor with built-in resistors manufactured by ROHM Semiconductor. It features a low saturation voltage of 40mV typical at IC/IB = 50mA/2.5mA, making it suitable for muting circuits. The device supports high collector currents up to 600mA. It is housed in an SOT-346 (SC-59) surface-mount package and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Low VCE(sat) optimized for muting circuit applications
• Capable of handling high collector currents up to 600mA

Applications

• Muting circuits
• High current switching applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm packaging details such as tape and reel specifications. Ensure the component meets the required RoHS compliance standards for your assembly process. Cross-reference the part number with official ROHM documentation to validate availability and production status before finalizing procurement plans.

Selection Notes

Select this component when low saturation voltage is critical for signal integrity in muting applications. Consider the 600mA current capability for load requirements. Verify that the SOT-346 package dimensions fit the PCB layout constraints. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the DTC363 series of NPN digital transistors from ROHM. It integrates base resistors to simplify biasing networks. The T146 suffix typically denotes the specific packaging configuration, such as cut tape or reel, which affects handling and placement during surface mount assembly processes.

Replacement Considerations

Check for direct equivalents with similar VCE(sat) and current ratings. Verify pin compatibility and package dimensions. Ensure replacement parts meet the same electrical characteristics and thermal performance requirements.
