The SMAHFL40A-H is a robust Transient Voltage Suppressor (TVS) Diode from Formosa Microsemi, available at Supreme Components International, an authorised distributor. This diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). Featuring a power dissipation of 400W and a standoff voltage of 40V, the SMAHFL40A-H offers reliable protection in a compact SMA package. Its fast response time and low clamping voltage ensure effective suppression of transient events, preventing damage to downstream components. Ideal for use in telecommunications, industrial control, and consumer electronics applications, this TVS diode enhances the reliability and longevity of electronic systems. Supreme Components International guarantees the authenticity and quality of this Formosa Microsemi component.
