RHR15120 15A 1200V Hyper-fast Diode 5dbi GSM Flat Antenna The MQ-3 module can detectThe RHRP15120 is a hyperfast diode with soft recovery. It is a silicon nitride passivated ion implanted epitaxial planar construction with half the recovery time of ultrafast diodes. These devices are designed to be used as freewheeling clamping diodes and diodes in a wide range of switching power supplies and other power switching Applications. It reduces power loss and electrical noises too. It has Hyper fast, soft recovery time, which reduces the
