The working principle of the SMBJ400E3/TR13 is based on a transient voltage protector or diode. Essentially, the TVS diode works in a manner similar to a Zener diode. When a high voltage transient is detected, the diode becomes forward biased, thus blocking the transient from reaching the equipment it is protecting. The diode then quickly clamps the voltage to a safe level. The diode continues to stay forward biased until the transient voltage drops to a safe level, at which point it returns to its reverse-biased state.

The SMBJ400E3/TR13 is an excellent choice for a wide variety of industries and applications due to its highly efficient transient protection. The device is quick and reliable in responding to transients, making it ideal for protecting delicate electronic components. Furthermore, the device’s low capacitance and low operating voltage make it excellent for protecting sensitive electronics.
