The SMAJ40A is a high-reliability, surface-mount Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. This unidirectional TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 400W and a standoff voltage of 40V, the SMAJ40A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its compact SMA package makes it ideal for space-constrained applications. Supreme Components International is an authorised distributor of SMC DIODES, ensuring you receive authentic and high-quality components. This TVS diode is suitable for various applications, including industrial control, automotive electronics, and consumer electronics.
