TVS diode is an electrical component designed to protect sensitive electronic equipment from overvoltage transients. The 1.5SMC15AHE3/9AT TVS diode is a type of unidirectional, bidirectional, unidirectional bidirectional or axial lead diode. It is typically used in applications such as automotive, industrial, consumer electronics and telecommunications.

The 1.5SMC15AHE3/9AT TVS diode is designed to provide an extremely high surge current capability. This can be up to 1.5 times the power rating of the device. The diode achieves this by using a FET-like P-type silicon layer, which acts as an open-collector field-effect transistor. The layer has an insulated gate, allowing it to be turned on and off by changing the voltage applied to the gate.

The 1.5SMC15AHE3/9AT TVS diode offers a low junction capacitance created by PN junctions, which allows it to respond quickly to large, fast-rising overvoltage transients. The low clamping voltage is also achieved due to this capacitance. The low clamping voltage is the most important parameter in determining the level of surge current protection provided. The diode also features low leakage current for improved efficiency.

The 1.5SMC15AHE3/9AT TVS diode\'s working principle is based on its design. When an overvoltage transient occurs, the diode begins to clamp the transient, limiting the rise in voltage and allowing the protected device to remain operational. The diode absorbs the energy of the transient with its floating junction. This transient is then drained to the ground, and the protected circuit remains intact.

The 1.5SMC15AHE3/9AT TVS diode is highly suitable for applications in a wide variety of electrical and electronic equipment such as industrial systems, consumer electronics, telecommunications and automotive. The diode can be used in junction or series configurations, allowing for flexibility in its application. Due to its high surge current ratings, fast response time, low clamping voltage and low leakage, the 1.5SMC15AHE3/9AT TVS diode is a reliable protection solution for sensitive electronics.
