The 18 nC gate charge at 4.5 V means a modest gate driver can switch it fast without excessive drive losses. With a junction temperature range from -55 to 175 °C, it handles the thermal cycling found in automotive under-hood or industrial power supplies.
No second-source or successor is listed in the official record, but the part is widely available through independent distribution.
The maximum Rds(on) is 5.2 mOhm at 40 A drain current with 10 V gate drive.
Yes, the STD80N3LL is ROHS3 compliant.
The part number STD80N3LL is a STMicroelectronics product code: STD indicates the STripFET family, 80 is the current rating in amperes, N3 indicates N-channel with 30 V rating, and LL denotes low on-resistance (low-loss).
