The 28 V reverse standoff voltage means the diode stays transparent on a nominal 24 V or 28 V supply, only conducting when the line exceeds 31.1 V (the minimum breakdown voltage). The 45.4 V clamping ceiling limits the voltage spike seen by the downstream silicon — a figure that matters when the protected IC's abs-max rating sits near that threshold. ## Bidirectional clamping for signal and DC rails A single bidirectional channel handles both positive and negative transients on the same line — useful on AC-coupled signals or bipolar supplies where two unidirectional diodes in anti-series would double the part count. The junction operates from -55°C to 150°C, covering the full industrial temperature band without derating the 600 W peak pulse capability at 25°C. The DO-214AA (SMB) body is a standard footprint shared across the SMBJ family; the same land pattern accepts the full voltage range from 5.0 V to 188 V. No power line protection is built in — this part is intended for signal and secondary DC rail clamping, not primary AC mains suppression. ## Active production, sourced per RFQ Diodes Incorporated lists the SMBJ28CA-13-F as Active.","metaTitle":"Diodes Inc SMBJ28CA-13-F TVS Diode, 600W, 28V Bidirectional","metaDescription":"Active Diodes Inc SMBJ28CA-13-F Zener TVS, 600W peak pulse, 28V reverse standoff, bidirectional, DO-214AA SMB.
