Product details

P-channel load switch for 24 V rails

The SI4435DYTRPBF: The 8-SO package fits standard surface-mount assembly lines.

Rds(on) and gate drive — what the numbers mean

Rds(on) is specified at 20 mOhm max with 8 A drain current and 10 V gate drive. Gate charge is 60 nC at 10 V. Input capacitance Ciss is 2320 pF at 15 V drain bias.

Temperature range and environment

Power dissipation is limited to 2.5 W at 25 °C ambient in the 8-SO package — a copper pour on the PCB landing pad is recommended to keep the junction below the derated limit at high load currents.

Sourcing and compliance

It is ROHS3 compliant.

Frequently asked questions
