    Products Detail

    BAT43 Overview


    Reverse leakage current from this device is 500nA volts at its maximum.For this device, the average rectified current is 200mA volts.In this case, forward current can reach 200mA.As you can see, the fuse's current rating is 200mA, which means that it can carry a maximum current for an indefinite period without losing too much performance.Phase diode rectifier is possible to use a surge current of maximum value 4A.Capacitance can cause the device to deliver a value of 7pF.Based on the data chart, the peak reverse is 500nA.

    BAT43 Features


    a maximal reverse leakage current of 500nA volts
    an average rectified current of 200mA volts
    a current rating of 200mA
    the peak reverse is 500nA
