• High-speed switching capability supported by a 300 MHz transition frequency suitable for general-purpose applications.
• Robust thermal performance allowing up to 500 mW power dissipation and operation up to 150°C junction temperature.

Applications

• General-purpose signal switching and amplification circuits
• Low-power digital logic interface applications
• Consumer electronics internal signal processing

Procurement Notes

Verify the specific suffix T5G against procurement requirements to ensure correct tape-and-reel packaging quantity and orientation. Confirm that the SOT-563 footprint matches the target PCB design guidelines. Cross-reference the manufacturer part number with official datasheets to validate the dual NPN configuration and electrical ratings before finalizing supply chain agreements.

Selection Notes

Select this component when a dual NPN configuration is required in a minimal footprint SOT-563 package. It is appropriate for designs needing 200 mA continuous current handling and 40 V blocking voltage. Consider the 300 MHz frequency response for moderate-speed switching needs. Ensure the 500 mW power dissipation rating aligns with the thermal management strategy of the host system.

Part Context

This part belongs to the family of small-signal dual transistors offered by onsemi. It serves as a compact alternative to discrete single transistors, reducing board space and assembly complexity. The SOT-563 package provides efficient thermal conduction relative to its size, supporting reliable operation in dense consumer electronic assemblies where multiple switching elements are necessary.
