Automotive-grade transient suppression with a known EOL date
The 1.5KE100CHE3/54: It clamps at 144V maximum with a reverse standoff of 81V, handling a 10.4A peak pulse current (10/1000µs waveform).
What the clamping and standoff ratings mean for your 24V or 48V bus
At 144V clamping, the diode limits the transient to a level that downstream semiconductors rated at 200V minimum can survive. The 10.4A peak pulse current at the 10/1000µs waveform defines the energy the part absorbs in a single surge event.
Obsolete — last-time-buy window closed, surplus sourcing now
Vishay lists the 1.5KE100CHE3/54 as obsolete. No official successor or second-source part number is recorded in the lifecycle entry. The last-time-buy window has passed; current availability is through independent surplus and broker channels.
