TVS (Transient Voltage Suppressors) diode is an important component used in a variety of electronic equipment’s protection for classifying transient voltages to prevent leakage current, overvoltage damages which can effect on the longevity of an electronic equipment.

SMBJ51D-M3/H is a unidirectional transient voltage suppressor diode which is constructed for solid state device with lower power losses and higher surge current capacities. SMBJ51D-M3/H commonly used for voltage and power protection and suitable for power supplies, secondary protection or any of the power-related electronic device.

Application field: SMBJ51D-M3/H is widely used in computer/office automation telecommunication/industrial equipment for overvoltage protection in telecommunications lines, power lines, and computer ports. Areas of applications include protection against voltage spikes caused by lightning, inductive load switching and other applications.

Working Principle: The working principle of SMBJ51D-M3/H is based on the P-N junction and avalanche voltage. In normal working state of SMBJ51D-M3/H, the P-N junction rectifier pass the current, but when overvoltage appears on the input side, voltage through P-N junction exceed the voltage withstand capability, and then passes current at each junction and trigger the avalanche breakdown, absorbing overvoltage, and declining output voltage successfully.

SMBJ51D-M3/H is an cost-effective and reliable solution to provide protection for a variety of electronic devices, from medical instruments, industrial equipment, consumer electronics to PCs, automotive, telecom/datacom, gaming, military & aerospace and other applications.

In short, SMBJ51D-M3/H is a successful transient voltage suppressor diode, which can protect electrical and electronic circuits from surge voltages, overvoltage, and lightning strikes. It also ensures the procedure of the electrical equipment and keep them work in normal conditions.
