SMF51CA with 2.5A 1uA 82.4V 200W 56.7V 51V 62.7V Bi-Directional SOD-123FL TVS ROHS is a bidirectional Transient Voltage Suppression (TVS) diode manufactured by Liown. It is a RoHS compliant, surface mounted device with single line bi-directional protection. It is designed to protect circuits against electrostatic discharges (ESD). It limits transient voltage induced by ESD, lightning, and other voltage transients to protect sensitive equipment from problems such as data errors and performance degradation. This device is optimized for use in general purpose and I/O applications and features low clamping voltage, low capacitance, low inrush current, and fast response time. It is rated for 2.5A of peak pulse current and features a working voltage rating of 82.4V, Vmax between 56.7V and 62.7V, and 200W power dissipation. The package used is the SOD-123FL.
