Reverse standoff voltage is 70V; breakdown occurs at a minimum of 77.8V. The clamping voltage at the 13.3A peak pulse current (10/1000µs waveform) is 113V max, limiting the voltage seen by the protected load. AEC-Q101 qualification means this part meets automotive-grade stress and reliability requirements — suited for 70V bus lines in engine bay or chassis domain ECUs, battery management systems, and DC motor drive circuits. ## DO-214AA SMB footprint and temp range The single unidirectional channel protects one signal or power rail per device. Operating junction temperature range spans -55°C to 150°C, covering the full automotive and industrial ambient envelope. The 1500W peak pulse rating is derated above 25°C per the datasheet curve — budget derating at 85°C ambient for realistic surge capability. ## Active production, sourced per RFQ Supplied on tape and reel per the standard SMB packaging. No official pin-compatible second source is listed on the Bourns record, but the 1.5SMBJ series covers multiple standoff voltages if a different rail needs protection on the same board.","metaTitle":"Bourns 1.5SMBJ70A TVS Diode, 70V, 1500W, DO-214AA","metaDescription":"Bourns 1.5SMBJ70A Zener TVS diode, 70V reverse standoff, 113V clamp, 1500W peak pulse.
