The SODJ15A-SH is a surface mount Transient Voltage Suppressor (TVS) diode manufactured by Leshan Radio. It is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. The 'J' in the part number suggests it is a TVS diode and '15A' indicates a standoff voltage of 15V.

Applications
