MOSFETs

N-channel MOSFET30 VSOT-23low RDS(on)

DO3400B is a 30 V N-channel MOSFET in SOT-23 for compact low-voltage switching. It offers low on-resistance and a typical total gate charge of 4.8 nC.

Best for

  • compact low-voltage load switching
  • power-management switching stages
  • applications using a 4.5 V or 10 V gate drive

Avoid if

  • the circuit requires a drain-source rating above 30 V
  • the application cannot provide adequate SOT-23 thermal dissipation

Check before use

  • maximum drain transient voltage
  • gate-source voltage limits
  • RDS(on) at the actual gate-drive voltage
  • continuous and pulsed thermal conditions
