Procurement Notes
Verify the specific suffix -T1B-A to confirm the embossed tape carrier packaging configuration. Confirm current product status as obsolete or end-of-life through official Renesas channels before finalizing procurement plans. Ensure compatibility with 2.5 V drive requirements for the intended application design.
Selection Notes
Select this component when a 16 V N-channel MOSFET capable of being driven directly by low voltage logic (2.5 V) is required. Consider the 27 pF input capacitance for switching speed requirements. Verify package availability and lifecycle status due to potential obsolescence.
Part Context
This part belongs to Renesas' portfolio of power MOSFETs for automotive and general-purpose applications. It complements other devices like the 2SK1587 and 2SK1581C series, offering specific characteristics for low-voltage switching tasks within the broader discrete semiconductor category.
Replacement Considerations
