MCR10FZHJ473 is a high vibration resistant, low capacitance T.V.S (Transient Voltage Suppressor) diode that can be used in a variety of applications. It is manufactured by Rohm, a Japanese company that specializes in the manufacture of integrated circuits, power supplies and other electronic components. The diode can be used to protect sensitive circuits from transient voltages, as it is able to handle high voltage spikes and prevent damage to the connected equipment. It is rated to handle up to 10V and is available in 10kO, 100kO and 1MO resistance ratings. It is RoHS compliant, meaning it does not contain hazardous chemicals.
