The 1.5SMBJ22A-H: At 22V reverse standoff, it clamps transients to 35.5V maximum, handling 42.3A of peak pulse current — this defines the surge capacity for a 24V nominal rail in an automotive ECU or sensor module. With AEC-Q101 qualification, the part is screened for automotive reliability: -55°C to 150°C junction temperature range, tested for high-temperature reverse bias and power cycling.
The SMB footprint is shared across the 1.5SMBJ family, so a single pad layout covers the whole voltage range from 5.0V to 170V without a board spin.
