Product details

Obsolete — last-time-buy sourcing

Vishay has marked the 1.5KE200HE3/73 as Obsolete (cite:). This part is now available through independent surplus channels.

AEC-Q101 TransZorb for automotive transient protection

Breakdown voltage is specified at 180V minimum, with a reverse standoff of 162V typical — appropriate for protecting 160V nominal DC rails against load-dump and inductive spike transients (cite:,).

DO-201AA axial package — board-fit note

Supplied in the DO-201AA (DO-27) axial-lead package, through-hole mounted. The 5.2A peak pulse current rating at 287V clamp is the thermal limit through the lead-frame and junction (cite:,). Single unidirectional channel — cathode banded. The part ships in Tape & Box (TB) format (cite:,).
