Procurement Notes
Verify the manufacturer origin carefully, as listings may attribute the part to Sanyo or Inchange Semiconductor Company Limited (ISC). Confirm the specific package variant (TO-3PB) and electrical ratings match your design requirements before ordering. Ensure the component meets safety standards for high-voltage applications.
Selection Notes
Select this component when high-speed switching capabilities are required alongside moderate current handling. The 450V breakdown voltage suits medium-to-high voltage DC-DC converters or motor control interfaces. Consider the TO-3PB package for its thermal management properties in industrial environments.
Part Context
This component belongs to the family of discrete semiconductor transistors manufactured by Sanyo. It is categorized under single FETs and MOSFETs. The part is distinct from similar models like the 2SK1424, which differs significantly in voltage rating and current capacity despite sharing the same manufacturer lineage.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements by matching the N-channel type, 450V Vds, 12A Id, and TO-3PB package specifications.
