The G3S06505H is a Schottky Barrier Diode (SBD) made by GPT. It is a TO-220 package that is RoHS compliant and has been designed for modern applications. It features an ultra-low voltage drop of 0.3 volts (ideal for low power circuitry), as well as low thermal resistance for maximum efficiency and reliability. The SBD also has a low temperature coefficient to ensure its performance is stable over a wide range of temperatures and operating conditions. With an average forward current of 1.5A and maximum reverse voltage of 5V, this device can be used for a variety of logic signal control applications such as power switching, ESD protection, and voltage level switching.
