24 V rail protection — 38.9 V clamp ceiling
Its 38.9 V maximum clamping voltage at the 16 A peak pulse current (10/1000 µs waveform) sets the voltage the downstream circuitry must survive — a key parameter for selecting the TVS for a given bus or power input.
600 W peak pulse — energy handling for industrial transients
The 26.7 V minimum breakdown voltage ensures the device starts conducting before the rail exceeds safe limits.
DO-214AA (SMB) — surface-mount footprint
Housed in the DO-214AA (SMB) package, the SMBJ24A-TR is a surface-mount device suitable for automated assembly.
