Overview
The 1SMA36AT3G is a transient voltage suppressor (TVS) diode designed by Littelfuse Inc. This component is part of the SMA series, which is intended to protect voltage-sensitive components from high voltage, high energy transients. Although the SMA series has been marked as End of Life (EOL) as of December 31, 2017, and is not recommended for new designs, it remains relevant for existing applications and maintenance. The recommended replacement series is the SMAJ series.
