General-Purpose TVS Diode

SMBJ170AActive

SMBJ170A TVS diode is a surge protection device designed based on the avalanche breakdown principle,designed to protect sensitive electronic circuits from ESD (electrostatic discharge),surges and other transient voltage interference. Due to its fast response (nanosecond level) and low leakage current characteristics,this device is suitable for over-voltage protection in communication interfaces,industrial control,power supply systems and automotive electronics.
