Its automotive-grade AEC-Q101 qualification and a junction temperature range extending to 175°C make it the part you specify when the standard IRLR2703 cannot guarantee reliability in an under-hood or high-ambient environment. ## On-resistance and gate drive — sizing the conduction loss Maximum Rds(on) is 45 mOhm at 14 A drain current with 10 V gate drive. That 45 mOhm number is the worst-case ceiling at 25°C junction; at 175°C the on-resistance roughly doubles, so the actual conduction loss in a hot engine bay runs higher than the room-temperature calculation suggests. The gate charge is 15 nC at 4.5 V, which means a standard 1 A gate driver can switch this FET in the low-microsecond range without excessive drive power.","metaTitle":"AUIRLR2703 N-Channel MOSFET, 30V 20A DPAK, AEC-Q101","metaDescription":"AUIRLR2703 N-channel HEXFET MOSFET, 30V, 20A, 45mΩ Rds(on) at 14A, AEC-Q101 qualified, 175°C Tj.
