Procurement Notes
Verify the specific ordering suffix H6433 against official Infineon documentation to confirm tape and reel quantities and marking codes. Ensure compatibility with PG-SOT-23 footprint requirements during PCB layout. Confirm that AEC-Q101 qualification meets specific project automotive standards. Check for any recent lifecycle status updates or alternative package options if volume requirements differ from standard reels.
Selection Notes
Select this component when a small-signal N-channel MOSFET with automotive qualification is required. The low gate charge and fast switching times suit high-frequency applications. Consider the thermal resistance characteristics for heat dissipation in dense layouts. Verify that the 60 V breakdown voltage provides sufficient margin for the target circuit's operating conditions.
Part Context
This part belongs to the BSS138 series of SIPMOS small-signal transistors manufactured by Infineon Technologies. The series is designed for general-purpose switching and amplification in space-constrained environments. The PG-SOT-23 package offers a compact solution for surface-mount assembly. The product line emphasizes reliability and compliance with strict environmental regulations.
Replacement Considerations
Cross-reference with other BSS138 variants such as BSS138W for SOT-323 packaging differences. Verify pinout compatibility before substituting with similar N-channel MOSFETs from other manufacturers. Ensure electrical parameters like RDS(on) and VGS(th) remain within acceptable limits for the existing design.
