The P6SMB100A with TVS SMB (DO-214AA) RoHS, is a device made by Formosa, which is a unidirectional Transient Voltage Suppressor (TVS). This TVS helps protect electronic devices from damage due to electrostatic discharge (ESD) or other overvoltage transients which may occur in normal operation. This device is RoHS compliant, meaning it is manufactured without hazardous substances like lead and mercury. It is also made in a compact DO-214AA package, so it is easy to install in tighter spaces. It is rated for 100V peak pulse power, with a breakdown voltage of 6 volts, and up to 400 watts peak power dissipation. This device is designed for general-purpose applications such as protection against ESD pulses, overvoltage transients, and other electrical hazards.
