24V rail clamp – 600W peak pulse in DO-214AA
The SMBJ24E3/TR13 is a Zener TVS diode designed to protect a 24V nominal rail. Its reverse standoff voltage is 24V, so the part sits across the rail without conducting until a transient pushes it above the minimum breakdown of 26.7V. The DO-214AA (SMB) surface-mount package keeps the footprint compact — about 4.6 mm × 3.6 mm — and the tape-and-reel delivery suits automated pick-and-place.
Active production – tape-and-reel availability
Microchip lists the SMBJ24E3/TR13 as Active.
Single-channel unidirectional – no power-line protection
This is a single unidirectional channel — it clamps only positive transients above breakdown. For AC or bidirectional lines, a different TVS (or two back-to-back) is needed.
