TO-220 Heat Sinks

Excess heat in your TO-220 parts can reduce output and damage circuits rapidly. Our TO-220 Heat Sinks lower thermal resistance to 1.0°C/W-10.0°C/W, ensuring your components stay efficient and robust.

Base Material

Aluminum or copper; alloy customization available upon request

Thermal Resistance

1.0°C/W to 10.0°C/W, suited for TO-220 package efficiency

Heat Dissipation Capacity

5 W to 50 W, designed for TO-220 component power ranges

Dimensions

Width: 20 mm to 50 mm; Height: 10 mm to 40 mm; Depth: 20 mm to 60 mm (customizable to fit TO-220 layouts)

Weight

0.02 kg to 0.5 kg, based on material and size for TO-220 integration

Product Description

Elevated temperatures in TO-220 packages weaken performance and cut durability, threatening your systems’ stability. These heat sinks deliver consistent cooling with exact fits, improving reliability and lifespan.

Fin Design

Vertical fins or folded fins (straight or wavy); fin spacing: 2 mm to 5 mm for airflow optimization

Mounting Type

Clip-on, screw-mount, or tab; tailored for TO-220 package attachment

Cooling Method

Passive (natural convection) or active (fan-assisted), depending on TO-220 load and airflow

Operating Temperature Range

-40°C to 125°C, with maximum base temperature rise of 30°C above ambient

Airflow Compatibility

Supports 5 CFM to 60 CFM, effective with case or external airflow

Surface Finish

Anodized aluminum or nickel-plated copper, improving durability and heat transfer

Noise Contribution

Silent in passive mode or below 30 dB with active cooling, minimal in TO-220 systems

Durability

Rated for 70,000+ hours under continuous TO-220 operation

Environmental Resistance

Resists dust (IP52 rating) and vibration (per IEC 60068-2-6) in electronic environments

Standards Compliance

Conforms to RoHS, UL 94V-0, and IPC-9592 for TO-220 safety and performance

Thermal Interface Compatibility

Compatible with thermal pads, grease, or tape for secure TO-220 contact

Technical Advantages

Inconsistent cooling under heavy loads can overheat your TO-220 parts and disrupt system balance. Our TO-220 Heat Sinks offer custom fin spacing from 2 mm to 5 mm, ensuring steady airflow tailored to your power demands.

Poor fit on varied boards risks heat buildup and component stress, slowing your output. Our heat sinks provide clip or screw mounts adjusted to your layout, securing tight contact for reliable heat transfer.

Avoiding Downtime with Customized Heat Sinks

High heat in TO-220 parts risks sudden failures and delays in your production runs. Our TO-220 Heat Sinks handle 5 W to 50 W, sustaining operation for 70,000+ hours without faltering.

Uncontrolled temperatures can degrade your chips and halt workflows, increasing expenses. Our heat sinks, weighing just 0.02 kg to 0.5 kg, keep your systems cool and dependable.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can TO-220 heat sinks handle sudden heat spikes in my regulators?

TO-220 heat sinks adjust fin density to manage rapid heat rises, keeping your regulators stable under spikes. That quick response prevents output drops or circuit damage.

Will your TO-220 heat sinks meet my charger’s custom cooling needs?

We customize TO-220 heat sinks to your charger’s exact layout and load, cooling parts fast for reliable use. Such tailored design boosts customer trust, driving your sales higher.

Are TO-220 heat sinks easy to tweak for my mixed board designs?

TO-220 heat sinks offer sizes from 20 mm to 50 mm wide, matching your varied layouts with no hassle. So, flexible sizing cuts your redesign time and costs.

How do your TO-220 heat sinks avoid mount stress on my amplifiers?

We craft TO-220 heat sinks with clip or screw options, spreading load even across your board’s tabs. This balanced fit stops stress cracks, keeping amplifiers steady.

Do TO-220 heat sinks scale fast for my urgent production runs?

TO-220 heat sinks meet urgent runs with batches up to 10,000 units, shipping in 2-4 weeks to your specs. That rapid delivery keeps your production on schedule without gaps.
