The SL1002A075SM TVS diode operates by clamping the voltage to a safe level when a transient voltage exceeds the diode's breakdown voltage. This protects downstream components from being damaged by the overvoltage event. Its low clamping voltage ensures that the voltage across the protected components is limited to a safe value. Its fast response time ensures that it quickly clamps the transient voltage, preventing damage.

Key specifications include the breakdown voltage, clamping voltage, peak pulse current, and capacitance. The breakdown voltage is the voltage at which the diode starts to conduct significantly. The clamping voltage is the voltage across the diode when it is conducting a specified peak pulse current. The capacitance is a measure of the diode's ability to store charge. Detailed specifications can be found in the Littelfuse datasheet for the SL1002A075SM. The operating temperature range is typically between -55°C and +125°C.
