Total gate charge is 60 nC at 10 V. ## Temperature range — rated for the harsh stuff That 175°C ceiling suits engine-bay electronics, downhole tools, and avionics power stages where ambient heat pushes junction temperatures past the usual 150°C limit. Surface-mount D-Pak (TO-252) with two leads and a tab. The tab orientation is marked by a chamfer on the package body — easy to see under magnification.
