Overview
The SMF6.0AT1G is a Transient Voltage Suppressor (TVS) diode from Littelfuse Inc., designed to protect voltage-sensitive components from high voltage and high energy transients. This component is part of the SMFxxA series, known for its excellent clamping capability, high surge capability, low zener impedance, and fast response time. Although the SMFxxA series 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 of older systems.
