The maximum drain-source voltage (VDS) is 40V.
The maximum continuous drain current (ID) is 33A at 25°C with VGS = 10V.
The maximum on-resistance (RDSon) is 21mOhm at VGS = 10V and ID = 10A, with a typical value of 17.8mOhm.
It is available in an SC-100 / SOT-669 surface mount package, also known as LFPAK56 or Power-SO8.
The operating junction temperature range is -55°C to 175°C.
The RoHS status is listed as RoHS3 Compliant, but this is unverified and low confidence.
The maximum gate threshold voltage (VGS(th)) is 4V at ID = 1mA.
