The SMF22CA with 35.5V 24.4V 22V SOD-123FL TVS ROHS is a surface mount transient voltage suppressor (TVS) diode manufactured by SUNMATE. It is made of silicone-based semiconductor materials, and is packaged in an SOD-123FL package—a short-leaded, flat version of the SOD-123 surface mount package. This component is designed to protect low-cost, low-voltage circuit boards from electrical surges, such as those caused by lightning, electrostatic discharge (ESD), and other high-frequency transients. It features a low clamping voltage, allowing for high speed and low-capacitance protection. Additionally, the SMF22CA is RoHS-compliant and comes in a tape and reel design for automatic insertion into surface mount circuit boards.
