Procurement Notes
Verify the specific suffix HTA against official Diodes Incorporated documentation to confirm tape and reel packaging details. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date with your production timeline to avoid discrepancies in electrical parameters or pinout definitions during procurement.
Selection Notes
Select this component when a small form factor is required alongside specific RF performance metrics. The 15 V voltage rating and 25 mA current limit define the operational boundaries. Consider the 4.5 dB noise figure at 500 MHz as a critical parameter for signal integrity. Confirm that the SOT-23-3 package aligns with the PCB layout constraints and thermal management strategy of the design.
Part Context
The BFS17HTA belongs to the discrete transistor category within Diodes Incorporated's portfolio. It serves as a specialized solution for RF applications where size and frequency response are prioritized. The SOT-23-3 package allows for automated surface mount assembly, supporting high-volume manufacturing processes common in consumer electronics and communication hardware sectors.
Replacement Considerations
Consult official manufacturer substitution guides for verified alternatives. Generic cross-references may not match the specific 1.3 GHz transition frequency or 4.5 dB noise figure requirements. Verify pin compatibility and electrical ratings before implementing any substitute part number in existing designs.
