Full-pack isolation — no extra insulator needed
The TO-220 Full Pack (PG-TO220-FP) package has a fully molded back — no exposed metal tab. The 36 W power dissipation ceiling at the case is the thermal budget; with the junction rated to 175 °C, the part can handle sustained high-current switching in a confined enclosure as long as the heatsink keeps the case temperature in check.
