The SMBJ300A is a unidirectional TVS diode from Littelfuse Inc. designed for transient voltage suppression in general purpose applications. It features a 300V reverse standoff voltage and a 486V clamping voltage, providing 600W peak pulse power dissipation under a 10/1000μs waveform. The device uses Zener technology and offers a fast response time of less than 1.0 picosecond from 0V to breakdown.
With a peak pulse current rating of 1.3A and low leakage current below 1μA, the SMBJ300A is suitable for protecting sensitive electronics from voltage transients, including ESD events up to 30kV per IEC 61000-4-2. The component is housed in a surface mount DO-214AA (SMB) package, which optimizes board space and supports high-temperature reflow soldering up to 260°C.
The operating temperature range spans -65°C to 150°C, making it suitable for a wide variety of environments. The part is claimed to be RoHS compliant, halogen free, and lead-free with matte tin plating, though these compliance assertions are unverified and based on generic series claims.
