The 1.5KE220HE3/54: The official lifecycle status is Obsolete — no last-time-buy window is stated, meaning the only channel is independent surplus or broker inventory.
The wide temp range suits under-hood or engine-bay placement where ambient heat plus self-heating from the surge must stay within the junction limit.
1500 W (1.5 kW) for a 10/1000 µs waveform. This is a standard TVS power rating for automotive transient protection.
As an obsolete part, it is sourced through independent distribution.
