600W peak pulse, 9V rail clamp
Unidirectional, single-channel Zener TVS in the DO-214AA (SMB) surface-mount package. The 39A peak pulse current rating at the 10/1000 µs waveform gives the thermal mass to absorb repetitive surges from inductive loads or hot-plug events.
Temperature grade and board fit
Operating junction temperature range -65°C to 150°C covers military/aerospace cold-soak and under-hood automotive hot-soak conditions. The DO-214AA footprint is a common SMB pad layout — the same land pattern serves the full SMBJ family, so a BOM swap between voltage variants requires no board spin.
