The single unidirectional channel means this is a one-direction clamp; for bidirectional protection on an AC or bipolar rail, a pair back-to-back or a dedicated bidirectional part is needed. AEC-Q101 qualified and rated Automotive grade — this TVS has passed the stress tests and process-change notification requirements of the Automotive Electronics Council. The -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles with margin; the 150°C upper limit is the Tj(max) for power derating, not the ambient operating ceiling. ## Package and board integration DO-214AA (SMB) surface-mount package — the standard footprint matches the SMB solder-land pattern in IPC-7351B. The Tape & Reel delivery format supports automated pick-and-place assembly; reel quantity is not specified here but follows the Bourns 1.5SMBJ series standard. No power line protection — the device is intended for signal-line or low-power DC rail transient suppression, not for AC mains or high-energy power bus clamping where a higher-energy MOV or TVS module would be specified.","metaTitle":"Bourns 1.5SMBJ85A-H TVS Diode, 85V, 1500W, DO-214AA SMB","metaDescription":"Bourns 1.5SMBJ85A-H 1500W TVS diode, 85V reverse standoff, 137V clamping, AEC-Q101 automotive grade.
