The SMDJ43A is a high-power, unidirectional Transient Voltage Suppressor (TVS) Diode manufactured by JSCJ (JCET). Supreme Components International is an authorised distributor of JSCJ components. This TVS diode is designed to protect sensitive electronic equipment from voltage transients caused by lightning, inductive load switching, and electrostatic discharge (ESD). With a peak pulse power dissipation of 3000W, the SMDJ43A effectively clamps overvoltage events, safeguarding downstream circuitry. Its 43V standoff voltage makes it suitable for a wide range of applications. The device is housed in a compact DO-214AB (SMC) package, facilitating easy board mounting and integration. This robust TVS diode offers excellent surge protection and long-term reliability, ensuring the safe and continuous operation of your electronic systems. Consider the SMDJ43A for superior transient voltage protection.
