650 V, 7 A CoolMOS™ CE — what this N-channel MOSFET brings to the switching supply
The TO-220 Full Pack package provides full isolation from the heatsink — no insulating pad needed, which simplifies assembly and improves thermal transfer to the mounting surface. That low gate charge keeps switching losses in check at moderate frequencies — expect clean transitions in the 50–150 kHz range without oversized gate drivers. The input capacitance of 440 pF at 100 V Vds confirms the part is optimised for hard-switching topologies, not resonant or soft-switching designs where higher Ciss can be tolerated.
No need to stockpile or search for a drop-in replacement yet — the CoolMOS™ CE family remains a supported portfolio.
Package and thermal handling — the Full Pack advantage
The TO-220 Full Pack (PG-TO220-3-FP) isolates the backside tab electrically, so the heatsink can be chassis-grounded without a mica washer or silicone pad. Maximum power dissipation is 28 W at case temperature — enough for a 15–25 W flyback converter when the junction is kept below 150°C.
