Dual 30 V N-channel in an 8-SOIC — load-switch and driver workhorse
The Infineon AUIRF7313QTR is a dual N-channel HEXFET MOSFET in an 8-SOIC package, rated for 30 V drain-source and 6.9 A continuous drain current per channel at 25°C case temperature.
175°C junction — military-temperature headroom
The -55°C to 175°C junction temperature range qualifies this part for avionics, satellite, downhole drilling, and other high-reliability environments where commercial or even industrial-grade parts would derate or fail. The 755 pF input capacitance at 25 V drain bias and 33 nC total gate charge at 10 V are moderate — a typical MCU GPIO or low-side driver can switch it at tens of kHz without excessive drive current, though the gate-drive loop should be kept tight to avoid ringing.
