Product Introduction

Overview

The 1SMB5.0AT3G is a Transient Voltage Suppressor (TVS) diode produced by Littelfuse Inc. This component is part of the SMB series, designed to protect voltage-sensitive components from high voltage, high energy transients. Although this 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 SMB series is known for its excellent clamping capability, high surge capability, low zener impedance, and fast response time.
