The Diotec 1.5SMC350A ESD Suppressor/TVS Diode is a unidirectional protective device designed to absorb and dissipate ESD and other transient voltages. It is constructed with a transient voltage suppressor (TVS) diode and an added series-connected suppressor element (SMC component) to further reduce the peak current. It features a maximum operating voltage rating of 300V, 1500W peak pulse power, fast speed response time (less than 1ns) and a small, low-profile, SMC (Surface-mount) package. The device provides a high level of protection by clamping voltage transients near the peak pulse power specified, even in harsh application environments. The 1.5SMC350A is suitable for use in applications requiring ESD, EFT, and surge protection in automotive, industrial, and consumer electronics.
