The SMAHFL440A-H is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components. This unidirectional TVS diode is designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage (Vrwm) of 44V, a breakdown voltage (Vbr) of 68.8V, and a clamping voltage (Vc) of 71.5V. With a power dissipation of 400W, the SMAHFL440A-H provides robust protection against surges caused by lightning, inductive load switching, and ESD events. Its compact SMA package makes it suitable for high-density circuit board applications. This diode is commonly used in telecommunications, industrial control, and consumer electronics to enhance system reliability and prevent damage from transient voltages.
