1N4148 Overview

An appropriate reverse voltage is 100V.For this device, the average rectified current is 200mA volts.Electronic or electrical devices produce heat as unwelcome byproducts of their primary functions.Forward current is allowed to reach a value of zero.The least amount of 500mW heat is produced by electronic or electrical devices (energy lost as heat).As for rectifiers current rating, rectifier is 200mA, which is the maximum current a fuse can carry wrectifierhout too much degradation.There is no maximum value for 4A surge current.Depending on the capacitance, the device can deliver a value of 0F.Datasheets indicate that the peak reverse is 5μA.
