The 38.9 V clamping ceiling means a 24 V bus sees the transient held below 39 V — well within the typical 40 V abs-max of downstream DC-DC converters and linear regulators on that rail. The 1500 W rating covers the energy in a standard industrial surge (IEC 61000-4-5 combination wave) at the secondary protection stage. ## Deployment and temperature envelope Operating junction temperature range spans -55°C to 150°C, covering under-hood automotive and industrial enclosure environments. Surface-mount on a standard SMB footprint — the DO-214AA package is shared across the 1.5SMBJ family, so a single PCB land pattern serves the full voltage range from 5.0 V to 170 V. No power line protection feature (internal crowbar or series element), so this is a pure shunt clamp for signal or low-impedance power rails.","metaTitle":"Bourns 1.5SMBJ24A-H TVS Diode, 1500W, 24V, AEC-Q101","metaDescription":"Bourns 1.5SMBJ24A-H Zener TVS diode, 1500W peak pulse power, 24V reverse standoff, AEC-Q101 qualified, DO-214AA SMB.
