26V unidirectional TVS — the clamping limit for a 24V rail
The SMBJ26A-13-F is a 26V reverse-standoff Zener TVS from Diodes Incorporated's SMBJ series, clamping at 42.1V max with a 14.2A peak pulse current (10/1000µs waveform). The 28.9V minimum breakdown voltage means the device starts conducting before the 42.1V clamp is reached, providing a defined avalanche window.
DO-214AA SMB package and temperature grade
The SMB footprint is a standard JEDEC outline — the same pad layout used across the SMBJ family, so a single PCB land pattern serves multiple voltage variants.
Active production — no obsolescence watch needed
The base product number SMBJ26 covers the entire voltage family; the -13-F suffix indicates the tape-and-reel packing option.
