Why Gallium Nitride (GaN) Chargers Are Replacing Traditional Bricks

For nearly four decades, silicon has been the undisputed king of power electronics. But silicon is rapidly hitting its thermal and electrical limits. Enter Gallium Nitride (GaN)—a crystal semiconductor with a bandgap over three times wider than silicon.

Because electrons travel through GaN with far less electrical resistance, components can be placed millimeters apart while switching electrical current thousands of times faster. The result? A 100W GaN charger that slips effortlessly into your pocket and stays cool to the touch.
