MOSFETs

P-channel MOSFET-40 VSOT-23power switching

DO4085A is a -40 V P-channel MOSFET in SOT-23, intended for compact low-side or load-switching applications within its rated voltage, current, and thermal limits.

Best for

  • Compact P-channel load switching
  • General power switching where -40 V capability is sufficient

Avoid if

  • The application requires a higher voltage rating
  • The design needs package dimensions or compliance data that are not supplied

Check before use

  • Maximum VDS and VGS
  • Current and junction-temperature derating
  • RDS(on) at the available gate drive
  • SOT-23 pin assignment
