9V working voltage, 600W surge rating
Its 600W peak pulse power rating (10/1000µs waveform) means it can absorb a 35.5A surge before the clamping voltage reaches 16.9V — enough for industrial and telecom secondary protection stages.
DO-214AA SMB package, wide temperature range
Active production — no obsolescence watch
Microchip lists the SMBJ9.0E3/TR13 as Active.
