650 V CoolMOS™ C7 in a PG-VSON-4 — what the field tech needs to know
The IPL65R230C7AUMA1 is an Infineon CoolMOS™ C7 N-channel MOSFET rated for 650 V drain-source with a continuous drain current of 10 A at 25 °C case temperature. It comes in a 4-lead PG-VSON-4 surface-mount package — a small footprint with an exposed pad underneath for heat sinking.
Gate charge and switching — sizing the driver
Total gate charge is 20 nC at 10 V gate drive. That is the charge the driver must push into the gate each switching cycle. At 100 kHz switching frequency, the average gate drive current is 2 mA — well within a standard MOSFET driver's capability, but at 500 kHz you are looking at 10 mA average, which starts to matter for driver thermal design. Input capacitance Ciss is 996 pF typical at 400 V drain-source. That is moderate for a 650 V device — the driver sees a manageable capacitive load, so rise and fall times stay clean without excessive ringing if the layout keeps the gate loop tight.
Package and mounting — PG-VSON-4 reality
The PG-VSON-4 is a 4-lead surface-mount package with an exposed thermal pad. The supplier device package designation is PG-VSON-4. The pad on the bottom is the drain tab — it needs a good thermal via array to the ground plane to get the 67 W power dissipation rating to work in practice. For rework, a hot-air station with a fine nozzle on the pad area works — the exposed pad is large enough that a standard reflow profile for lead-free solder handles it. No special moisture sensitivity level is listed, but standard MSL handling applies for a plastic package.
