3.High Thermal Performance MOSFET

Panasonic’s CSP MOSFETs with High Thermal Performance

Resin Sealed PKG

Thermal distribution

Resin Sealed PKG

Temperature 52℃
Higher heat generation, worse thermal performance

21℃ lower

CSP

Thermal distribution

CSP

Temperature 31℃
Lower heat, better thermal performance

*Same PCB size but CSP part is 57% smaller PKG

Use case

Fast charging for smartphone lithium-ion battery

The lower on resistance on MOSFET, the lower heat and capable for higher charging current.
