The SM4NT40CA-H is a high-performance, 40V bidirectional TVS Diode manufactured by Formosa Microsemi. Designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD), this diode offers a robust and reliable solution. With a power dissipation of 400W, it effectively clamps transient voltages to safe levels, preventing damage to downstream components. The SM4NT40CA-H is housed in a compact and industry-standard DO-214AC (SMA) package, making it suitable for a wide range of applications where space is a constraint. Supreme Components International is an authorised distributor of Formosa Microsemi components, ensuring you receive genuine products with full traceability and support. This TVS diode is ideal for use in automotive, industrial, and consumer electronics applications.
