An engine-control unit or transmission controller that sees 125°C ambient on a hot day still has 25°C of junction margin before reaching the absolute-maximum rating. The DO-214AA (SMB) surface-mount package is the standard footprint for this power class — the same pad layout used across the 1.5SMBJ family, so a single PCB land pattern serves the full voltage range from 5.0V to 220V without a board spin. ## Peak Pulse Power and Clamping Performance Derate linearly above 25°C per the power-derating curve typical for this package — at 125°C the effective power handling drops to roughly 60% of the 25°C rating, so the actual transient capability in an under-hood environment is lower than the headline figure. The clamping voltage of 103V at 14.6A peak pulse current defines the protection ceiling: any downstream component rated below 103V sees the full transient voltage. A 100V-rated MOSFET on the same rail has only 3V of headroom at the clamp point — the designer should verify the downstream device's avalanche capability against the TVS clamp.","metaTitle":"Bourns 1.5SMBJ64A TVS Diode, 1500W, 64V, DO-214AA","metaDescription":"Bourns 1.5SMBJ64A automotive AEC-Q101 TVS diode, 1500W peak pulse power, 64V reverse standoff, DO-214AA SMB.
