Working principle of SMBJ70HE3/52

The working principle of the SMBJ70HE3/52 TVS diode is based on the principle of a Zener diode. When the voltage exceeds the breakdown voltage of the diode, a large amount of current is allowed to flow in the reverse direction, dissipating the excess energy and providing protection to the device.

The SMBJ70HE3/52 TVS diode is designed to offer superior surge and transient suppression while maintaining a low clamping voltage. Unlike other transient voltage suppressors, the SMBJ70HE3/52 offers a low clamping voltage even during high energy transient events. This provides protection by clamping the voltage at low levels, allowing the device to keep functioning within the design parameters.

The SMBJ70HE3/52 is designed for unidirectional protection and is intended for use in power supply and signal circuit applications. When used in applications like DC-DC converter and Ethernet protection, the diode can help reduce the risk of damage due to ESD and transients. The device is also designed to provide protection in both common and lightning modes of EOS.
