The P6SMB550CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection applications in portable communications, computing, and video equipment. This device features a 550V breakdown voltage with a peak pulse power dissipation of 600 watts and operates over a temperature range of -55°C to +150°C. The SMB (DO-214AA) surface mount package provides a compact form factor with fast response times of less than 5.0 picoseconds from 0V to minimum breakdown voltage. The P6SMB550CA is RoHS compliant and halogen-free, making it suitable for IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 surge protection standards. Its bidirectional configuration and high voltage rating make it ideal for protecting sensitive circuits in high-voltage transient environments.
