The TPSMF4L40A is a high-performance 400W Transient Voltage Suppressor (TVS) diode manufactured by Diotec. Supreme Components International is an authorised distributor of Diotec, ensuring you receive genuine components. This TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a reverse standoff voltage (Vrwm) of 40V, the TPSMF4L40A effectively clamps overvoltage events, preventing damage to downstream circuitry. It is housed in a compact DO-214AC (SMA) package, making it suitable for space-constrained applications. This robust diode offers excellent clamping capability and fast response time, ensuring reliable protection for your valuable electronics. Applications include automotive, industrial, and consumer electronics.
