Procurement Notes
Verify the specific suffix -V-1EX against the manufacturer's official datasheet to confirm RoHS compliance and tape-and-reel packaging specifications. Ensure the component matches the original Sanyo or onsemi manufacturing lineage. Cross-reference the part number with authorized distributors to confirm authenticity and avoid counterfeit risks during procurement processes.
Selection Notes
Select this component when designing circuits requiring a 450V N-channel MOSFET with moderate current handling. The 1.4-ohm resistance suits applications where conduction losses must be balanced with cost. Consider the TO-220AB footprint for board space constraints. Evaluate thermal management needs based on the 5A continuous drain current rating under expected operating conditions.
Part Context
This MOSFET originates from the Sanyo product line, now integrated into onsemi's portfolio. It serves as a discrete power semiconductor solution for medium-power electronics. The device replaces older generations of similar voltage-rated transistors, offering standardized pinouts and performance metrics compatible with existing industrial and consumer power design architectures.
Replacement Considerations
Consult official substitution guides for equivalent N-channel MOSFETs with matching 450V ratings and comparable Rds(on) values. Verify pin compatibility and thermal characteristics before swapping components.
