Overview
The 1.5SMC36AT3G is a Transient Voltage Suppressor (TVS) diode produced by Littelfuse Inc. This component is designed to protect voltage-sensitive components from high voltage, high energy transients. It is part of the SMC series, which is known for its excellent clamping capability, high surge capability, low zener impedance, and fast response time. Although the 1.5SMC36AT3G is marked for End of Life (EOL) as of December 31, 2017, and is not recommended for new designs, it remains relevant for existing applications and maintenance purposes.
