If the downstream DC-DC converter or IC has an absolute maximum rating below 77.4V, an additional TVS or a series resistor may be needed to share the energy — but for most 48V automotive loads (which tolerate 60–80V transients), this clamp is well within the safe operating area. The 400W peak pulse power rating is derated linearly above 25°C; at 150°C junction temperature the derating factor is typically 0.65× per the AEC-Q101 derating curve, so the effective pulse power at the upper end of the -55°C to 150°C range is about 260W. That still covers the majority of automotive load-dump and inductive kickback events.","metaTitle":"SMAJ48AQ-13-F TVS Diode, 400W, 48V, AEC-Q101, DO-214AC","metaDescription":"Diodes Inc SMAJ48AQ-13-F automotive TVS, 400W peak pulse, 48V standoff, 77.4V clamp, AEC-Q101.
