The P4SMA33A is a transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. This unidirectional device features a breakdown voltage range of 34.4 to 37.8 volts with a peak pulse power dissipation of 400 watts and a maximum reverse voltage (VRM) of 28.2 volts. The device is housed in a compact DO-214AC (SMA) surface mount package and offers fast response times of less than 1.0 picosecond, making it ideal for protecting sensitive circuits against transient overvoltages. The P4SMA33A is RoHS compliant and halogen-free, conforming to JEDEC standards and suitable for IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge protection applications.
