SMAJ300CAE3/TR13

TVS, short for Transient Voltage Suppressors, is a device used to protect sensitive electronics from transient voltage events. The SMAJ300CAE3/TR13 is a Transient Voltage Suppressor Diode (TVS Diode) designed to protect a system from damage caused by overvoltage or ESD (electrostatic discharge). The diode is intended for use in portable electronic devices where an enhanced level of protection is required for voltage transients caused by ESD, as well as a low operating voltage of +3.0V.

The SMAJ300CAE3/TR13, a unidirectional diode, is designed to protect from voltage surges in either AC or DC circuits. The diode has a nominal breakdown voltage of 300V and a maximum clamping voltage (Vmax) of 425V, when the current is 8A. The device also features an operating temperature range from -55°C to +150°C and a low reverse leakage current of 0.1μA. The diode also features a high surge capacity of 62A peak pulse current when operated at +25°C. The SMAJ300CAE3/TR13 further incorporates current limit protection, which protects against more severe applications.

The SMAJ300CAE3/TR13 diode is commonly utilized in applications such as cell phones, computers, consumer electronics, automotive, and power conversion applications. The TVS diode can also be used for industrial applications such as EMI filtering, circuit protection, and signal protection. The applications and uses of the SMAJ300CAE3/TR13 diode depend on its ability to provide circuit protection from voltage transients.

The working principle of the SMAJ300CAE3/TR13 diode involves the principles of capacitance and inductance. This is because the diode works in conjunction with a properly designed circuit. The diode works by providing a low impedance circuit between a potential voltage source and the system it is protecting. The diode acts as a capacitor which stores the energy from the voltage spike and discharges it as an equal and opposite current. Upon discharge the diode helps in dissipating the energy that was present in the voltage spike and thus provides circuit protection. The inductance of the diode also helps dampen or absorb the voltage spike, thus providing protection from voltage overshoots.

The working principle of the SMAJ300CAE3/TR13 diode is based on providing circuit protection by absorbing voltage spikes, providing low clamping voltage, and supplying high surge temperature. These features, along with its ease of use and compact size, make the SMAJ300CAE3/TR13 diode an ideal choice for numerous circuit protection applications.
