The UES1503 has specific electrical characteristics, including the forward voltage drop, reverse recovery time, maximum forward current, and peak reverse voltage. The forward voltage drop specifies the voltage drop across the diode when it is conducting. The reverse recovery time indicates how quickly the diode switches from conducting to blocking. The maximum forward current specifies the maximum current the diode can handle continuously. The peak reverse voltage specifies the maximum reverse voltage the diode can withstand without breakdown.
