The SMF5951A is a high-power Transient Voltage Suppressor (TVS) Diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components. This diode is designed to protect sensitive electronic equipment from voltage transients caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. With a peak pulse power dissipation of 5000W, the SMF5951A effectively clamps transient voltages to a safe level, preventing damage to downstream components. Its 51V standoff voltage makes it suitable for a wide range of applications. The DO-214AB (SMC) package offers excellent thermal performance and ease of board mounting. This TVS diode is ideal for use in power supplies, communication equipment, industrial controls, and automotive systems where reliable overvoltage protection is critical.
