Key Features
- High-Quality Aluminum Construction: Lightweight yet excellent thermal conductivity (~205 W/mK) ensures rapid heat transfer away from your IC.
- Black Anodized Finish: Increases thermal radiation efficiency by up to 25% compared to bare aluminum, while also providing corrosion resistance.
- Compact 25mm Form Factor: Small enough for breadboard-adjacent projects and tight PCB layouts without obstructing nearby components.
- Universal TO-220 Compatibility: Fits LM7805, LM7812, LM7809, LM317, TIP31, TIP41, IRF540, IRFZ44N, and virtually all TO-220 packaged devices.
- Multi-Fin Design: Maximizes surface area for superior passive convection cooling without requiring a fan.
- Easy Installation: Slides directly onto TO-220 tab; can be secured with M3 screw through standard mounting hole for vibration-proof attachment.
- Prevents Thermal Throttling: Keeps regulator junction temperature well within safe limits, maintaining stable 5V output even under sustained load.
Why You Need a Heatsink for Your LM7805
The LM7805 voltage regulator converts excess voltage into heat. When dropping from 12V to 5V at 500mA, the IC dissipates approximately 3.5W of power - enough to reach dangerous temperatures (>125 degreesC) within seconds without proper cooling. This 25mm aluminum heatsink dramatically reduces operating temperature, preventing thermal shutdown, output voltage drift, and premature component failure. It's an inexpensive investment that protects your entire circuit.
Why Choose This Heatsink?
- 100% authentic quality aluminum - no recycled or impure alloys
- Precision-machined fins for consistent thermal performance across every unit
- Expert technical support to help you calculate thermal requirements for your specific project
- Affordable bulk pricing for production runs and classroom kits
Thermal Design Guide
| Input Voltage | Output Current | Power Dissipated | Heatsink Needed? |
| 7V -> 5V | 500mA | 1.0W | Recommended |
| 9V -> 5V | 500mA | 2.0W | Required |
| 12V -> 5V | 500mA | 3.5W | Essential |
| 12V -> 5V | 1A | 7.0W | Essential + airflow |
Formula: Power = (V_in V_out) x I_load. This heatsink comfortably handles up to ~3-4W in still air conditions.
Project Ideas
- Regulated Power Supply: Build a reliable 5V bench supply using LM7805 with this heatsink for stable, cool operation during long testing sessions.
- Arduino & Raspberry Pi Projects: Power microcontroller boards from 12V battery packs with a properly cooled voltage regulator for field deployments.
