The 1.5SMB100CA: For a 85.5V working bus, this clamp margin — roughly 1.6× the standoff — is typical for a 1500W TVS in this voltage class. The 1500W peak pulse rating (10/1000 µs) means the diode absorbs a single 1 ms surge up to that power without failing. Derating applies for shorter or longer pulses and elevated ambient temperatures.
