Low 0.32V forward voltage and fast <5ns reverse recovery suit OR-ing and protection applications. The common-anode configuration connects both cathodes separately for dual independent circuits sharing one supply. 30V\/200mA per diode for automotive signal and low-power supply routing.","working_principle":"Each diode uses a metal-semiconductor (Al-N) junction that allows majority carrier conduction. The absence of minority carrier storage enables sub-5ns reverse recovery. The low barrier height of the Al-N junction gives 0.32V forward voltage, significantly lower than silicon PN diodes (0.7V), reducing conduction loss in OR-ing and protection circuits.","pin_description":"
