QSX1TR

Single Bipolar Transistors Overview

The QSX1TR is a single NPN bipolar junction transistor manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a TSMT6 (SC-95) package with dimensions of 2.9 mm in length, 1.6 mm in width, and 1.1 mm in height. The device operates with silicon technology and supports a maximum collector-emitter voltage of 12 V and a continuous collector current of 6 A. Key electrical parameters include a collector-base voltage of 15 V, an emitter-base voltage of 6 V, and a gain bandwidth product of 250 MHz. Power dissipation is rated at 1.25 W, with a maximum operating temperature of +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the official ROHM datasheet to ensure compatibility with required packaging options such as cut tape or reel configurations. Confirm that the component meets RoHS compliance standards if environmental regulations apply to your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Single Bipolar Transistors Selection Notes

Select the QSX1TR when a robust NPN transistor with 6 A current handling capability is required in a small form factor. Ensure the application voltage does not exceed the 12 V collector-emitter rating. Consider the 250 MHz transition frequency for medium-speed switching needs. Verify thermal management requirements given the 1.25 W power dissipation limit in the TSMT6 package.

Single Bipolar Transistors Part Context

This component belongs to ROHM Semiconductor's discrete bipolar transistor portfolio, specifically within the BJT category. It is engineered for reliability in automotive, industrial, and consumer electronics sectors. The TSMT6 package provides efficient heat dissipation relative to its size, supporting its use in dense PCB layouts where thermal performance and current capacity are critical design constraints.

Single Bipolar Transistors Replacement Considerations

Consult official substitution guides for equivalent NPN transistors with matching 12 V/6 A ratings and TSMT6 footprint compatibility. Verify pinout alignment and electrical parameter overlaps before replacing the QSX1TR in existing designs.
