The 5.0SMCJ45A-AQ is a high-performance TVS (Transient Voltage Suppressor) diode manufactured by Diotec. This diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage (VBR) of 45V, the 5.0SMCJ45A-AQ offers reliable overvoltage protection. It is housed in a compact DO-214AB (SMC) package, making it suitable for space-constrained applications. Supreme Components International is an authorised distributor of Diotec components, ensuring you receive genuine and high-quality products. This TVS diode is part of the broader TVS diode category and is commonly used in various industrial, automotive, and consumer electronics applications to enhance circuit reliability and prevent damage from voltage surges.
