The SMF85CA with Bi-Directional SOD-123FL TVS ROHS is a bidirectional, epoxy-coated transient voltage suppressor produced by Taiwan Semiconductor Manufacturing Corporation (TWGMC). This device is designed to protect electronic components from electrostatic discharge and overvoltage transients. The SMF85CA is equipped with an SOD-123FL surface-mount package and is lead-free (RoHS compliant), making it ideal for applications that require small size and space-saving boards. The SMF85CA features a reverse-bias standoff voltage of 5.0V and a nominal breakdown voltage of 5.6V. When the voltage across the device surpasses these levels, the SMF85CA quickly clamps the voltage and diverts its current away from the sensitive components to ground. The SMF85CA offers excellent level of ESD protection, up to 15KV. This device is suitable for use in consumer electronics, automotive, and industrial applications.
