SM15T56AY

Transient Voltage Suppressor (TVS) diodes are electronic components used to protect sensitive components from extreme voltage transients. The SM15T56AY is a Uni-polar Transient Voltage Suppressor (TVS) type diode manufactured by Samsung Semiconductor. It is used to protect sensitive electronic components from voltage transients and surges that typically arise from lightning-induced events. The SM15T56AY is designed to clamp transients of up to 15.6V, and has a power dissipation rating of 2W.

The SM15T56AY is designed using pin-compatible technology and is capable of operating at temperatures of up to 85 degrees Celsius (185°F). The diode is packaged in a 14-pin TO-220 package with a maximum reverse stand-off voltage of 5 Volts and a maximum clamping voltage of 16 Volts. The SM15T56AY diode is designed to provide ESD, power surge, and transient protection for sensitive electronic components. It is designed to handle up to 15.6V of voltage transient events as well as provide up to 2W of power dissipation.

The SM15T56AY diode works by providing a path for the transient voltage to be clamped at a safe limit. When the voltage across the diode exceeds the breakdown voltage of the diode, the device starts to conduct and clamps the voltage. This will cause the voltage to drop to a safe level. The reverse leakage current of the diode is also very low, allowing it to protect sensitive components from leaking voltage and current.

The SM15T56AY diode is used in a variety of applications, including automotive, industrial, and consumer electronics. It is commonly used to provide protection for microcontrollers, data converters, circuit breakers, and switched mode power supplies. It can also be used to protect inductors, transistors, and relays from overvoltage transients. The SM15T56AY diode is an ideal solution for applications where high power dissipation and high signal integrity are required.

In summary, the SM15T56AY is a Uni-polar Transient Voltage Suppressor (TVS) type diode manufactured by Samsung Semiconductor. It is designed to provide ESD, power surge, and transient protection for sensitive electronic components. It can handle up to 15.6V of voltage transient events as well as provide up to 2W of power dissipation. The device is packaged in a 14-pin TO-220 package and is primarily used in automotive, industrial, and consumer electronics applications.
