TO-247 heatsink pack for discrete semiconductors

This pack contains five TO-247 heatsinks designed to dissipate heat from power transistors and similar discrete devices. Each block measures 38 by 34 by 12 mm and suits audio amplifiers, switching regulators or other through-hole power packages. The parts are supplied new and ready for immediate assembly.

Limits of natural convection on small fin area

Without forced airflow the thermal resistance remains relatively high, so sustained high-current operation may exceed safe junction temperatures. The compact 38 by 34 mm footprint also restricts the number of devices that can be mounted on a dense board. Builders needing lower thermal resistance or higher power density should consider larger extrusions or active cooling.

Questions about this item

Should I buy a single heatsink or the 5-piece pack?

The product is sold as a pack of five TO-247 heatsinks, so you receive five identical blocks in one purchase.

What does the 38x34x12mm size mean for fitting a TO-247 transistor?

Each block measures 38 mm by 34 mm by 12 mm, providing a mounting surface that matches the TO-247 package outline for direct component attachment.
