The 1.5KE36CHE3/54: This means it can clamp a 28.8 A surge to 52 V maximum, protecting downstream circuitry from transients like load dump or inductive kickback in automotive 24 V systems.
Vishay has marked the 1.5KE36CHE3/54 as obsolete.
A functional replacement would need the same 1.5KE package (DO-201AA), 29.1 V standoff, 1500 W peak pulse rating, and bidirectional configuration — but board-level verification is required.
