# SMBJ14A-HF (Component)
## Description
23.2VC Clamp 25.9A@10/1000us Ipp TVS DIODE SMB(DO-214AA)
The SMBJ14A-HF is a unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from high-voltage transient events such as ESD (electrostatic discharge), lightning-induced surges, and switching spikes. It is part of the SMBJ series, commonly used for general-purpose surge protection in compact surface-mount designs.
It is housed in a DO-214AA (SMB) surface-mount package, making it suitable for automated PCB assembly and space-constrained applications.
