RH1 Diode

RH1 Diode designed as a low forward voltage drop, low reverse current, and a high surge current capability. Basically, these types of diodes have high current capacity with a maximum recurrent peak reverse voltage VRRM 400V. This diode also known as the  silicon rectifier.Its low forward voltage drop makes it ideal for the reverse polarity protection circuits. It also features faster switching speeds and hence can be used in high-frequency switching circuits.

A diode designed as a semiconductor device specifically acts as a one-way switch for current. It permits flow of current easily in one direction, but severely restricts current from flowing in the opposite direction. The two terminals of the diode known as the anode and cathode. The most common applications of diode includes converting AC to DC, isolating signals from a supply, and mixing signals. The 2 sides of the diode doped differently. One side is the “p-side”, this features a positive charge. The opposite side reffered as the “n-side”, this has a negative charge. Both of these sides are layered together to form what is known as the “n-p junction” where they meet. The figure below indicates the diode symbol:

Diodes also reffered as rectifiers because they modify the alternating current (ac) into pulsating direct current (dc).  Based on their supported diode type, voltage, and current capacity, they are rated. Diodes have polarity, determined by an anode (positive lead) and cathode (negative lead). Most diodes allow current to flow only when positive voltage  applied to the anode.
