MOSFET Heat Sinks

Switching power fast in your electronics builds up heat that can slow or stop your systems. Our MOSFET Heat Sinks, made from aluminum or copper, take heat away quick to keep your setups running smooth. 

Base Material

Aluminum or copper; specific alloys customizable upon request

Thermal Resistance

0.1°C/W to 1.4°C/W, optimized for MOSFET high-frequency thermal efficiency

Heat Dissipation Capacity

20 W to 1500 W, suitable for MOSFETs in high-frequency and power-switching applications

Dimensions

Width: 30 mm to 350 mm; Height: 15 mm to 150 mm; Depth: 30 mm to 300 mm (customizable to fit specific designs)

Weight

0.2 kg to 8 kg, varying with material, fin count, and size for MOSFET needs

Product Description

Lots of fast switches in MOSFETs make heat that weak cooling can’t handle, causing breaks or low power. Our heat sinks give strong cooling for your designs, keeping every switch fast and safe. 

Fin Design

Extruded, skived, or bonded fins (straight or pin); fin pitch: 1 mm to 5 mm for effective dissipation

Mounting Type

Screw-mount, clip-on, or thermal adhesive; designed for secure MOSFET module attachment

Cooling Method

Passive (air-cooled) or active (fan-assisted), depending on power and environment

Operating Temperature Range

-40°C to 140°C, with maximum allowable base temperature rise of 60°C above ambient

Airflow Compatibility

Supports 5 CFM to 180 CFM, effective with natural or forced airflow in MOSFET systems

Surface Finish

Anodized (aluminum) or nickel-plated (copper) for corrosion resistance and heat radiation

Noise Contribution

Silent (passive) or <40 dB (active cooling), minimal acoustic impact in power systems

Durability

Rated for 50,000+ hours of operation under high thermal and electrical stress

Environmental Resistance

Resistant to dust (IP54) and humidity (up to 90% RH non-condensing); vibration per IEC 60068-2-6

Standards Compliance

Meets RoHS, UL 94V-0, and IEC 60747 standards for MOSFET safety and performance

Thermal Interface Compatibility

Pre-applied thermal paste or compatibility with high-performance TIMs (e.g., silicone-based)

Technical Advantages

Our MOSFET heat sinks stick tight with clips or screws, stopping heat from sitting in one spot. They pull heat good with air blowing soft or hard, fitting your machine’s air setup. 

Thin fins or wide ones cut from metal move heat out fast, keeping your parts cool. That quick pull stops hot spots, so your MOSFETs work strong without slowing down.

Industry Applications

Power Supplies

Cools MOSFETs in wall chargers, keeping phones and laptops powered up steady all day. 

Car Audio

Takes heat from amplifiers in car speakers, making sound loud and clear on every ride. 

Battery Packs

Handles heat in electric bike battery controls, letting riders go long without stops. 

Residential Lights

Pulls heat from dimmer switches, keeping room lights steady and bright every night. 

Robot Arms

Keeps MOSFETs cool in factory robot controls, moving parts fast for big jobs. 

Drone Motors

Manages heat in flight power boards, helping drones fly high and far every trip. 

Fast Cooling with MOSFET Switching

MOSFET switches push your systems hard and need cooling that won’t quit. Our MOSFET heat sinks use tight fin builds to move heat quick, keeping power steady in every job. 

Weak cooling can let heat pile up, making your electronics fail or lose speed over time. We shape our heat sinks with air or fan help, so your setups stay fast and tough no matter the load.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

What lead times can be expected when ordering custom MOSFET heat sinks for production runs?

Custom orders ship in 2-4 weeks, depending on specs like sizes (30-350 mm) or fin designs (straight or pin). Fast turnaround keeps production on track without sacrificing quality, easing supply chain worries. 

How do heat sinks reduce maintenance costs for your MOSFET systems?

Heat sinks use aluminum or copper with anodized finishes to fight wear and heat buildup, lasting 50,000+ hours in tough setups. This long life cuts down on replacements and downtime, saving money while keeping products steady. 

Can MOSFET heat sinks be adapted for both small-scale and large-scale electronics designs?

Yes, they come in sizes from 30 mm to 350 mm wide and mounting options like clips or screws, fitting compact gadgets or big power units. This range simplifies inventory and scales builds easily without extra hassle. 

What thermal conductivity benefits come with our MOSFET heat sinks?

Aluminum offers 200 W/m·K and copper hits 400 W/m·K, pulling heat fast from switches to keep systems cool. High conductivity boosts performance and cuts energy waste, making products stand out in fast-switching markets. 

How does quick heat removal improve both manufacturing costs and end-user satisfaction?

Heat sinks move heat out fast with tight fins, hitting steady cooling in minutes and saving energy during tests. Quick cooling lowers build costs and keeps end-user gear running smooth, driving sales in speed-hungry markets.
