The SMCJ1.5KE33AHE3-TP is an ESD suppressor, also known as a transient voltage surge suppressor (TVS) diode, manufactured by Micro Commercial Components (MCC). This device is designed to protect circuits from transient voltage and current spikes, which can occur due to electrostatic discharge (ESD) or other inductive and capacitive sources. It has an operating voltage range of 1V to 33V and a reverse stand-off voltage of 20V Maximum. This device is designed with small surface mounting package and features low profile, increased ESD protection levels, and a low operating capacitance of just 27pF. It is suitable for applications such as communication base-stations, automated test equipment, consumer electronics, and other industrial control systems.
