The 1.5KE510A: The reverse standoff voltage is 434V — the TVS does not conduct at normal operating voltage below this level, so it sits across a 400V DC bus without leakage.
Supplied in a DO-201AA (DO-27) axial-lead through-hole package — the leads are crimped into the PCB holes and soldered; the body is epoxy-encapsulated and handles wave-solder profiles without issue.
As a standard catalog part, Littelfuse typically provides RoHS and REACH compliance declarations. Specific documentation (UL recognition, IEC certification) is not listed in the available record — confirm with the supplier at RFQ for your jurisdiction.
