What the ratings mean for the power stage
The Infineon ISC0806NLSATMA1 is a 100 V N-channel MOSFET from the OptiMOS™ 5 family, housed in a PG-TDSON-8-7 package. It delivers up to 97 A continuous drain current at case temperature and a maximum on-resistance of 5.4 mOhm at 50 A, 10 V gate drive. Gate-drive logic is flexible: the datasheet specifies Rds(on) at both 4.5 V and 10 V, so the part works with 5 V logic-level gate drivers as well as traditional 10 V drives. Input capacitance is 3400 pF at 50 V Vds — a practical number for estimating switching losses in hard-switched topologies running above 100 kHz.
Package and mounting
The PG-TDSON-8-7 is an 8-lead power DFN with an exposed drain pad. Surface-mount soldering on a multi-layer PCB with thermal vias under the pad is expected to reach the 96 W power dissipation at case temperature. The 2.5 W dissipation at ambient temperature (Ta) is the limit without a heatsink — design the PCB copper area accordingly.
Lifecycle and compliance
The ISC0806NLSATMA1 is listed as Active in production and ROHS3 compliant.
