In normal operation below 5.0V, the diode draws only microamps of leakage current (typically 50uA at VRWM). When a transient voltage exceeds the breakdown voltage (VBR = 6.40-7.07V at 1mA), the TVS diode avalanches and clamps the voltage. At the peak pulse current (IPP = 53A for 10\/1000us waveform), the clamping voltage is 9.2V maximum. The 600W rating refers to the peak pulse power dissipation (VCL x IPP = 9.2V x 53A = 488W, derated to 600W at lower currents). The A suffix indicates unidirectional (protects against positive transients only; for bidirectional protection, use SMBJ5.0CA). The unidirectional device also protects against negative transients by forward-biasing the diode, clamping at approximately -1.5V. The SMB package (DO-214AA) is smaller than SMC but larger than SOD-123, with typical footprint of 4.3x3.6mm. The device meets IEC 61000-4-2 ESD protection of +\/-30kV (contact discharge) and IEC 61000-4-5 surge protection. Typical applications include 5V power supply input protection, USB port ESD protection, and general-purpose I\/O line protection. The junction capacitance is 250pF typical at 0V, which limits its use on high-speed signal lines.","pin_description":"
