The 28×28×15mm heatsink is a medium-profile aluminium heat sink for power transistors, MOSFETs, and TO-220/TO-247 packaged components, supplied as a pack of two.

At 15 mm tall, this 28×28×15mm heatsink provides good thermal mass and fin depth for components that dissipate a few watts continuously. It covers the standard footprint of TO-220 power transistors, L298N motor driver ICs, LM317 regulators, and similar through-hole packages. In addition, the aluminium construction keeps weight low while offering effective passive heat dissipation.

Key Features of the 28×28×15mm Heatsink

• Dimensions: 28 mm × 28 mm × 15 mm — fits TO-220, TO-247, and similar power packages
• Aluminium construction — lightweight with good thermal conductivity
• Parallel fins for efficient passive heat dissipation
• Suitable for power transistors, MOSFETs, LDO regulators, and motor driver ICs
• Pack of 2 — cover both channels of a dual H-bridge or motor driver in one order

Use Cases

• Cooling power transistors and MOSFETs in motor driver circuits
• Thermal management for LM317, LM338, and other linear voltage regulators
• Cooling L298N and similar dual H-bridge motor driver ICs
• DIY power supply and amplifier builds requiring passive transistor cooling

Works Well With

• 9×9×12mm Heatsink for A4988/DRV8825 — smaller heatsink for compact stepper driver ICs on the same controller board
• 50mm Axial Cooling Fan 5V/12V/24V — add active cooling alongside the heatsink for sustained high-current operation
