SMBJ10A-HRA

The SMBJ10A-HRA is an axial-leaded TVS diode designed to protect against high-frequency transients associated with lightning and other electrostatic discharge events. Its robust encapsulation provides superior protection against thermal, mechanical and electrical stresses. It is constructed from a pair of ultra-low capacitance high-speed diode die, enabling it to deliver avalanche-like performance at high frequencies.

The SMBJ10A-HRA is primarily used in communication systems that are sensitive to high frequency transient and ESD events, such as digital VoIP (voice over IP) systems. Its low clamping voltage and fast response time enable it to protect against ESD pulses of up to 8 kV and rising transients of up to 2.5 kV.

The working principle of the SMBJ10A-HRA is based on avalanche breakdown. The diode is constructed from an avalanche diode with a built-in fast response time. When the voltage applied to the anode of the diode exceeds the breakdown voltage of the diode, a large current flows, reducing the forward voltage drop. The current continues to flow until the applied voltage decreases below the breakdown voltage of the diode.

The SMBJ10A-HRA offers superior ESD protection and fast response time. It features a low leakage current of less than 1 μA, a clamping voltage ranging from 8.2 to 13.2 volts, and a peak power dissipation of up to 500 watts. It also offers superior surge protection in applications up to 100 Mhz. This makes the SMBJ10A-HRA an ideal choice for protecting sensitive electronics in communication systems and other applications exposed to high-frequency transients and ESD.

In summary, the SMBJ10A-HRA is a TVS diode designed to protect against high-frequency transients and ESD events in a variety of applications. Its low clamping voltage and fast response time enable it to protect sensitive electronics from damage associated with ESD pulses and ringing transients. Its low leakage current and peak power dissipation make it suitable for a variety of applications utilizing sensitive electronics. With its ability to provide superior surge protection up to 100MHz, the SMBJ10A-HRA is suitable for wireless and digital communication systems.
