FETs

P-channel MOSFET-30 VSOT-23Power switchingLow gate charge

DO3401B is a -30 V P-channel SOT-23 MOSFET for compact power-path and load-switching designs where a specified 52 mOhm maximum RDS(on) at -10 V gate drive is suitable.

Best for

  • Compact P-channel high-side switching
  • Low-voltage power-path control
  • General-purpose load switching

Avoid if

  • Gate drive cannot provide adequate negative VGS for required conduction loss
  • The application requires documented automotive or safety qualification
  • A larger package is needed for higher thermal dissipation

Check before use

  • RDS(on) at the actual VGS and drain current
  • PCB thermal resistance and junction temperature
  • SOT-23 pinout: gate pin 1, drain pin 2, source pin 3
  • Compliance and lifecycle status
