The SMBJ45A-13: Its 72.7V clamping voltage at 8.3A peak pulse current (10/1000µs waveform) means a downstream IC rated for 80V sees a safe voltage during a transient event — the clamp engages before the IC's abs-max is reached. For repetitive surges or elevated ambient, derate per the datasheet curve — the junction temperature stays within the -55°C to 150°C range when the pulse energy is within the SOA.
It is a unidirectional, single-channel device.
