The SMBJ5339B-TP part is a 5.0A Surface Mount Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Components (MCC). This diode offers an operating voltage range of 5.0 to 170 Volts and is designed for bidirectional ESD/EOS protection. It has an ultrashort response time of less than 1.0ns and can withstand up to 8kV ESD contact and up to 15kV ESD air discharges. Its low capacitance of 0.50pf helps to minimize signal distortion. It is compliant with IEC61051-2, UL8750, RoHS, and REACH standards and is suitable for use in telecommunications, industrial and consumer applications.
