Transient Voltage Suppressors (TVS) are widely used devices to protect sensitive electronic components from overvoltage or lightning-induced power surges. A transient voltage suppressor is an electronic component that prevents voltage spikes from damaging sensitive electrical components. The SMBJ11A is a low-power axial leaded device designed for general circuit protection from transients. It has two silicon chips connected in inverse parallel and has low clamping voltage. SMBJ11A is most commonly used in automotive, consumer electronics, military and industrial markets.

The SMBJ11A has a peak power dissipation of 5.0W, clamping voltage of 14V, test current of 5.0A, and stand-off voltage of 11V. It is rated for intermittent overvoltage transients up to 1500W peak pulse power. The device is ideal for protection of circuits against voltage transients induced by lightning and other unattenuated surges. It also has very low leakage current and can protect from overvoltage transients without sacrificing the surge current handling ability.

The working principle of a SMBJ11A is based on the zener diode technology. It uses two zener diodes and a back-to-back configuration which helps to protect from overvoltage transients. The two diodes are connected in inverse parallel and act as a transient suppressor. When the voltage across the SMBJ11A increases to the breakdown voltage, the forward current of the diode increases exponentially, and the excess current is diverted through the diode itself. This helps to protect the sensitive electronic components from any overvoltage or lightning-induced power surge.

The SMBJ11A has a low clamping voltage and a low stand-off voltage, which makes it an ideal protection device for sensitive electronic components. The device has a low leakage current and can protect from overvoltage transients without sacrificing the surge current handling ability. It has a small form factor and can be easily mounted on a circuit board. It is also widely used in consumer electronics and automotive applications.

In conclusion, the SMBJ11A is a low-power axial leaded device designed for general circuit protection from transients. It has a low clamping voltage, test current and stand-off voltage. It is rated for intermittent overvoltage transients up to 1500W peak pulse power and works on the zener diode technology. It is an ideal protection device for sensitive electronic components and is widely used in the automotive, consumer electronics, military and industrial markets.
