Infineon Technologies P-channel power MOSFETs

A P-channel MOSFET uses hole flow as the charge carrier, which has less mobility than the electron flow used in N-channel MOSFETs. In functional terms, the main difference is that P-channel MOSFETs require a negative voltage from the gate to the source (V_GS) to turn on (as opposed to an N-channel MOSFET, which requires a positive V_GS voltage). This makes P-channel MOSFETs the ideal choice for high-side switches. The simplicity of the design is beneficial for low-voltage drives applications and non-isolated POLs, where space is limited.
