1N4737A


[ Detailed Data ]

In its simplest form, a diode consists of a single p-n junction, which is created by doping a semiconductor material with impurities to produce two regions with different electrical properties. When a forward voltage is applied to the diode, current flows easily in the forward direction, but is blocked in the reverse direction.
