28V rail clamp — Zener TVS in DO-214AA
Its 28V reverse standoff voltage means it will not conduct at the normal operating voltage, only during an overvoltage event — so it sits across a 24V or 28V DC supply without leakage issues.
Sourcing and fit for production
As an active Microchip part, the SMBJ28CE3/TR13 is sourced through our distribution channel against an RFQ. No power line protection feature — this is a signal or low-power rail clamp, not a mains surge protector.
