1SMC18AT3 Description

Short technical summary and product information.

The 1SMC18AT3 is a unidirectional Zener transient voltage suppressor from ON Semiconductor, part of the 1SMC5.0AT3 series. It is designed to protect voltage-sensitive components from high voltage, high energy transients with excellent clamping capability and fast response time.

 

Key electrical specifications include a clamping voltage of 29.2 V at peak pulse current, a peak pulse current rating of 51.4 A at 1 ms, and a peak pulse power rating of 1500 W at 1 ms. The device features an ESD rating of Class 3 (>16 kV) per the Human Body Model and a response time of less than 1 ns. It has a forward surge current rating of 200 A.

 

The 1SMC18AT3 is housed in a surface mount DO-214AB (SMC) package with a modified L-Bend lead style. It is supplied in tape and reel packaging with a standard quantity of 2500 units per reel. The device is suitable for general purpose applications including communication systems, automotive, power supplies, and industrial equipment.
