The SM15T6V8AY is a type of TVS - Diodes, and is used in many applications requiring surge protection. It is designed to protect sensitive electronic equipment from overvoltage transients, such as those caused by lightning or electrical faults. By providing a fast response time, the SM15T6V8AY offers excellent protection from high voltage surges.

The SM15T6V8AY is composed of two back-to-back zener diodes connected in series. These two diodes are connected in opposite directions so that the device can suppress the surge for both positive and negative overvoltages. The two zener diodes act as a voltage clamp, diverting the excess voltage away from sensitive components until the voltage returns to normal.

When an electrical surge is detected, the zener diodes in the device quickly act to reduce the voltage level and protect the connected equipment from damage. The device can attract and dissipate current up to a certain amount depending on the breakdown voltage. The SM15T6V8AY can be configured in the form of a two-stage diode including an internal withstand voltage (CW) and an external voltage protection (VPR). The SM15T6V8AY can also be daisy chained in series with other similar devices to provide further protection from a larger surge.

The SM15T6V8AY offers various applications such as power supplies, communication systems, charge pumps, and audio equipment. It is suitable for use in high-voltage control and lighting applications, and can help suppress voltage transients such as electrical noise, ESD, or surges caused by lightning strikes. Furthermore, it is also widely used in the automotive industry for engine control systems, EPS systems, electric power steering systems, and ECU protection applications.

The SM15T6V8AY is designed to provide reliable protection from electrical surges, and its fast response time helps to minimize the damage caused by these transient voltages. The device is rated to withstand surges up to 8 volts, and is RoHS compliant. The SM15T6V8AY is a reliable and cost-effective solution for protecting applications from transient voltages.
