  • DC-DC converter high-side switches

The IPD50P04P4L-11ATMA1 from Infineon Technologies is a -50V P-channel power MOSFET in a compact SOT-223 surface-mount package. It features low on-resistance of 50 mΩ, logic-level gate drive compatibility, and is designed for high-efficiency switching applications. The device is well-suited for automotive and industrial load switching, reverse polarity protection, and power management circuits where space and efficiency are critical.

The IPD50P04P4L-11ATMA1 operates as a P-channel enhancement mode MOSFET. When a negative gate-source voltage below the threshold is applied, a conductive channel forms between source and drain, allowing current flow. The low RDS(on) minimizes conduction losses during the on-state. As a P-channel device, it simplifies high-side switching circuits by eliminating the need for a gate drive voltage above the supply rail, unlike N-channel alternatives. The logic-level gate threshold allows direct drive from 3.3V or 5V microcontrollers.
