700 V N-channel in a TO-252 — what the CoolMOS P7 brings to the board
The Infineon IPD70R1K4P7SAUMA1 is a 700 V N-channel MOSFET from the CoolMOS P7 series, housed in a surface-mount PG-TO252-3 package. It is designed for hard-switching topologies in power supplies, adapters, and lighting ballasts where the combination of high-voltage blocking and low gate charge keeps switching losses in check.
The 158 pF input capacitance at 400 V drain-source confirms the small die size; the driver IC does not need a high peak current to charge the gate.
