Thermal-Electric Separation Red 2020 SMD LED

Advantages of Thermal-Electrical Separation LED Package vs. Regular Package

Better Heat Dissipation

Thermal path (heat) and electrical path (current) are separated.

Heat flows directly from the chip to the PCB/MCPCB without interference from electrical pads.

Result: lower junction temperature, higher reliability, longer lifetime.

Higher Power Handling

Because heat is managed more efficiently, the LED can safely run at higher currents and higher power density.

Regular packages often limit drive current due to poor heat conduction.

Improved Electrical Isolation / Safety

No risk of short-circuit between thermal pad and electrodes, since they're isolated.

Safer for high-voltage or special applications (e.g., UV, horticulture, automotive).

Simplified PCB Design

In regular packages, the big thermal pad is often tied to either Anode or Cathode, which forces the PCB layout to follow certain rules.

With thermal-electrical separation, designers can freely route electrical pads without being constrained by the heat sink pad.

Result: more flexible array and module design.

Higher System Efficiency

Lower thermal resistance → less energy wasted as heat.

Stable optical output over time (less light decay).

✅ In short:
A Thermal-Electrical Separation LED package provides better heat dissipation, safer electrical isolation, higher reliability, and more flexible PCB design compared to regular packages.

Thermal-Electrical Separation led, it has 3 pads: Anode, cathode and heat dissipation pad The heat dissipation pad is isolated from the anode and cathode electricity pad.	Regular leds with 2 pads only: One pad for anode and another
