The SMASF11A-Q1-H is a high-quality Transient Voltage Suppressor (TVS) diode from Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components. This unidirectional TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It is housed in a compact SMA package, making it suitable for space-constrained applications. With a reverse standoff voltage of 11V and a peak pulse power dissipation of 400W, the SMASF11A-Q1-H provides robust overvoltage protection. Its fast response time and low clamping voltage ensure effective protection against transient events. This diode is ideal for use in automotive, industrial, and consumer electronics applications where reliable surge protection is critical.
