700 V N-channel in a SOT223 — where the rating limits bite
The Infineon IPN70R2K0P7SATMA1 is a 700 V N-channel CoolMOS MOSFET in a PG-SOT223 surface-mount package. The 700 V drain-source rating places it in offline flyback auxiliary supplies, 400 VDC bus pre-regulators, and LED lighting ballasts where the primary-side switch sees a reflected voltage plus leakage spike.
Package and mounting
Rds(on) is specified at 2 Ohm maximum with 500 mA drain current and 10 V gate drive.
Package thermal reality — the SOT223 drain tab is the heatsink
The 6 W maximum power dissipation assumes the tab is connected to a sufficient copper pour.
Active lifecycle and ROHS3 compliance
ROHS3 compliance is confirmed.
