Power dissipation is rated at 203 W at the case — that number assumes an infinite heatsink; real designs need to derate against the thermal resistance of the chosen heatsink and airflow. The TO-220AB tab is the primary thermal path; a good thermal interface and a proper mounting torque keep the junction below 175°C at full load. If you are reviewing a BOM for a motor-drive or power-supply line that used this part, you are not under a lifecycle squeeze. ## Sourcing posture We source the BUK7507-55B,127 through independent distribution.
