Product details

P-channel load switch for 55 V rails

The Infineon IRLR9343TRPBF is a HEXFET® series P-channel MOSFET rated for 55 V drain-source breakdown and 20 A continuous drain current at a 25 °C case temperature.

175 °C junction — thermal headroom for tight enclosures

The junction temperature rating extends to 175 °C. The gate threshold voltage is specified at 1 V maximum with 250 µA drain current.

Sourcing and quoting

For volume requirements or scheduled releases, the active lifecycle status means the factory pipeline is open and no allocation shadow hangs over the line item.
