For a 24 V-rated input stage with a 40 V abs-max rating, the 38.9 V clamp leaves a slim but workable margin — check the downstream IC's absolute maximum against this figure. The 38.6 A peak pulse current is the maximum surge the device can absorb at the 10/1000 µs test waveform without failing. For a real-world transient shorter than 1000 µs (like an ESD or lightning-induced spike), the device can handle significantly more current — the datasheet's peak-pulse-power derating curve tells you how much. The 1500 W rating is the energy ceiling; stay under it and the TVS survives thousands of events. ## Temperature range and board fit The DO-214AA (SMB) package is a standard surface-mount footprint with a large copper pad on the cathode end — the board's copper area under the package directly sets the thermal resistance for pulse power dissipation.","metaTitle":"Bourns 1.5SMBJ24CA TVS Diode, 1500W, 24V, Bidirectional","metaDescription":"Bourns 1.5SMBJ24CA bidirectional TVS diode, 1500W peak pulse power, 24V standoff, 38.9V clamping.
