Dual 100V N-channel in a PG-TDSON-8-4 — what it handles
Each channel has a maximum on-resistance of 61mOhm at 16A and 10V gate drive — the number that sets the conduction loss in a synchronous rectifier or half-bridge leg. The 29W maximum power dissipation per device is a package-limited ceiling; in practice the PG-TDSON-8-4 (Infineon's PowerVDFN with exposed pad) relies on the PCB copper area for thermal spreading.
Gate drive and switching — what the 7nC Qg means
Total gate charge is 7nC at 10V — a low figure that keeps the gate-drive energy per cycle small. For a 100kHz switching frequency the average gate current is about 0.7mA per channel, well within the output capability of a standard MOSFET driver or a microcontroller GPIO with a series resistor. Input capacitance Ciss is 490pF at 25V Vds. Combined with the low Qg, this part switches cleanly without excessive ringing when the gate loop inductance is kept under a few nH — a practical layout guideline for the PG-TDSON-8-4 footprint.
Automotive qualification and production status
The IPG16N10S461ATMA1 carries AEC-Q101 qualification and is listed with an active product status. It is ROHS3 compliant.
