TVS (transient voltage suppressor) diodes are unidirectional devices that protect against transients by conducting and diverting these currents away from the sensitive components of the circuit. The SMB10J20AHE3/5B is an example of a TVS diode used in various applications. This paper will discuss the application fields in which the SMB10J20AHE3/5B is used as well as its working principle.

Application Fields

The SMB10J20AHE3/5B is specifically designed to protect against over-voltage transients such as those induced by lightning, inductive load switching, and electrostatic discharges. As a result, this diode is commonly used in power supplies, telecommunications, networking equipment, automotive electronics, and any other application that requires a robust level of signal protection. This diode also features an optional protective coating which can protect against corrosion or other environmental exposures.

The SMB10J20AHE3/5B offers a 600W peak pulse power (100us waveform) rating with excellent clamping capability and low surge resistance. The diode is also available with a variety of voltage and current ratings making it suitable for a range of applications. For instance, the diode is available with surface-mount and hole-mount versions to meet different circuit board design requirements.

Working Principle

The SMB10J20AHE3/5B is a unidirectional device designed to protect against transients and surges. The working principle of this device is based on the principle of avalanche breakdown, which occurs when an electric field sufficiently amplifies the current. The diode then channels the surge current away from the sensitive components of the circuit and through the external wire and resistor.

The SMB10J20AHE3/5B is designed with a state-of-the-art architecture that helps to minimize breakdown voltages and ensure reliable operation. The device also features a relatively low capacitance which helps to reduce electromagnetic interference (EMI) and avoid potential audio/video interference. The diode also features robust voltage clamping and low surge resistance for added protection.
