Gate charge totals 19 nC at 10 V, which keeps the gate-drive current modest: at 100 kHz switching, the average drive current is about 1.9 mA, well within the capability of a small driver IC or a microcontroller output with a series resistor.
The 150 V drain-source rating suits 48 V telecom rectifiers, 72 V battery systems, and 100 V bus architectures where the MOSFET must survive load-dump transients without avalanche failure.
Engineers need the datasheet to verify electrical parameters like Rds(on), gate charge, and package dimensions for design-in.
Buyers need to quickly find authorized distributors, compare pricing, and check stock to complete a BOM line.
Lifecycle status determines whether the part can be sourced long-term or if a replacement must be qualified.
When a part is unavailable or EOL, engineers and buyers need a drop-in equivalent to avoid redesign.
Lead time directly impacts production schedules and inventory planning for procurement teams.
Automotive designs require parts with AEC-Q101 qualification; confirmation avoids costly compliance issues.
