Product details

1 mOhm Rds(on) at 100 A — the switching loss floor

The IRFS7434TRL7PP: The device is rated for a drain-to-source voltage of 40 V and a continuous drain current of 240 A at a case temperature of 25 °C.

Gate charge and input capacitance — what the driver sees

The total gate charge is 315 nC at 10 V, and the input capacitance is 10250 pF at a 25 V drain-source bias. These numbers tell the gate-driver designer what current is needed to hit the target switching frequency. A 315 nC gate charge at 100 kHz switching requires an average gate drive current of about 31.5 mA, which is well within the capability of a standard MOSFET driver, but the peak current during the Miller plateau needs to be higher to avoid excessive switching losses.

Frequently asked questions

What is the Rds(on) value of the IRFS7434TRL7PP?

The drive voltage for achieving the minimum and maximum Rds(on) is specified at 6 V and 10 V respectively.

What package is the IRFS7434TRL7PP available in?

The device is supplied in a TO-263-7 (D2PAK-7) surface-mount package, which is a D²Pak variant with six leads plus a drain tab.

What is the closest functional equivalent to the IRFS7434TRL7PP?

The peer IPD50R950CEAUMA1 is a CoolMOS CE N-channel MOSFET, but it is a 500 V device with a 950 mOhm Rds(on) and a 4.3 A current rating. It is not a functional equivalent for the 40 V, 240 A, 1 mOhm class of the IRFS7434TRL7PP.
