Clamping window and surge handling
The 1N6286A-E3/73: The standoff voltage of 36.8 V sits comfortably below the 40.9 V minimum breakdown, so the device stays off during normal rail operation — it only clamps when a transient pushes the node above breakdown.
DO-201AA axial package for board-level protection
Through-hole DO-201AA leads get wave-soldered or hand-soldered into the PCB — the axial form factor and lead length give thermal relief during surge events and make this the standard footprint for AC-line entry protection in power supplies and industrial equipment. Tape-and-box packaging puts this in single-unit sleeves rather than a reel — the 1.5KE supplier device package designation matches the standard power-TV S body style used across the series.
Wide temperature range and sourcing reality
Rated -55°C to 175°C junction temperature — the full industrial and automotive temperature band. The 175°C ceiling gives headroom for hot-ambient designs where transient surge heating pushes the junction above what lower-rated parts can survive. Sourced through independent distribution; availability and lead time confirmed against your BOM quantity at RFQ.
