The 28 V reverse standoff voltage sits just above a nominal 24 V or 28 V DC rail, so the diode stays transparent during normal operation and only conducts when the line exceeds the 31.1 V minimum breakdown threshold. The single bidirectional channel means the same device protects both polarities on a signal pair or an AC line — no need to series two unidirectional parts. The DO-214AB (SMC) package footprint is shared across the SMCJ family, so a layout designed for a 5.0 V or 40 V variant accepts this 28 V part without board changes. The 45.4 V maximum clamping voltage at 33 A peak pulse current sets the upper voltage that downstream components must survive. For a 28 V rail, that is a 62 % headroom above the nominal — typical for a TVS protecting a DC bus with a 20–30 % transient margin. The 31.1 V minimum breakdown voltage ensures the device does not trigger on normal rail ripple or load transients within the operating envelope. No stock-holding claim is made; the part is sourced per RFQ through our supply channel.","metaTitle":"SMCJ28CAE3/TR13 TVS Diode – 1.5 kW, 28 V Standoff, DO-214AB","metaDescription":"SMCJ28CAE3/TR13 Zener TVS, 1500W peak pulse, 28V reverse standoff, 45.4V clamping, DO-214AB.
