AI summary

WST4041-ES is a compact -40 V P-channel MOSFET for low-side? No—its P-channel polarity is suited to high-side and power-switch arrangements when the circuit provides suitable negative VGS drive.

Best for

Compact P-channel load switches
DC/DC power-path switching
PWM and charging circuits

Avoid if

A guaranteed low-resistance specification is required with gate drive other than -10 V or -4.5 V
The application cannot dissipate heat through the PCB

Check before use

VGS drive level and transient margin
RDS(on) at the actual gate voltage
Drain current derating and board thermal resistance
Pin orientation: pin 1 gate, pin 2 source, pin 3 drain
