Introduction to SMAJ160

SMAJ160 is a series of transient voltage suppressor (TVS) diodes designed to be integrated into electronic equipment to provide protection from high-voltage surges and electrostatic discharges. It has a maximum continuous operating voltage of 150 V, a breakdown voltage of 160 V, a peak pulse current of 1.5 A and an operating temperature range of -55 to 125 °C.

Applications of SMAJ160

SMAJ160 is especially suitable for using in applications requiring primary and secondary level surge and electrostatic protection. This includes applications such as flashlights, mobile phones, digital cameras, portable medical, automotive, consumer, and industrial electronics. It can be used to protect any device with an exposed metal surface such as a printed circuit board traces, cordless phones, etc. from electrostatic discharges. It is also used to protect against electrical surge from lightning strike, short circuit events, and other external sources of disturbance.

Working Principle of SMAJ160

SMAJ160 works on the principle of avalanche breakdown. It contains a Zener diode which breaks down when a certain voltage is reached. When a transient voltage, such as an electrostatic discharge, is applied to the diode, it quickly breaks down and begins to conduct. This conducts the high energy surge current to ground and away from the protected device. Once the surge has completed, the diode is quickly returned to its non-conducting state.The diode can also limit the peak voltage that is applied to the protected device. The diode will quickly limit the voltage to a safe level to ensure that any components on the circuit are not damaged.

Conclusion

The SMAJ160 TVS diode is an effective solution for providing primary and secondary level surge and electrostatic protection. It works on the principle of avalanche breakdown, which quickly conducts high-power surges away from a protected device and limits the peak voltage to a safe level. It is suitable for use in many applications such as flashlights, mobile phones, automotive, and industrial electronics.
