The P6SMB120A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a breakdown voltage range of 114–126 V with a peak pulse power dissipation of 600 watts and a peak forward surge current of 100 amps. The device is housed in a compact SMB (DO-214AA) surface mount package and is RoHS compliant and halogen-free. With typical response times of less than 1.0 picosecond and a temperature coefficient of 0.1% per °C, the P6SMB120A provides reliable protection against transient overvoltages in applications requiring IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge protection.
