Product details

1500 W bidirectional TVS for automotive transient protection

The 1.5KE47CHE3/73: The DO-201AA axial package is a through-hole form factor that handles the 1.5 kW pulse without secondary heatsinking — the lead frame itself sinks the surge energy into the PCB copper.

Obsolete — last-time-buy sourcing through independent channels

Vishay lists this part as Obsolete. No official successor order code is recorded. The 1.5KE47CHE3/73 carries the TransZorb trademark and the Automotive, AEC-Q101 series designation.
