100 V N-Channel with low Rds(on) for high-efficiency switching
The AUIRL7766M2TR: The 10 mOhm typical Rds(on) at 31 A, 10 V keeps conduction losses low in high-frequency DC-DC converters and motor-drive output stages. With a junction temperature range of -55 to 175 °C, it suits automotive under-hood and industrial ambient environments where thermal cycling is a given.
Gate drive and switching behaviour
The gate threshold voltage is 2.5 V max at 150 µA drain current, meaning a 5 V logic-level gate drive turns the device fully on without a separate gate driver. The total gate charge is 66 nC at 4.5 V, so the switching losses at moderate frequencies stay manageable — a 100 kHz hard-switched converter draws about 6.6 mA from the gate drive. The maximum gate-source voltage rating is ±16 V, leaving headroom above the typical 10 V drive used to achieve the rated Rds(on).
