Product details

Obsolete — last-time-buy sourcing

The 1.5KE440-E3/73: Vishay lists the 1.5KE440-/73 as Obsolete.

1.5 kW TransZorb — clamping and breakdown ratings

The reverse standoff voltage is 356 V, meaning the device does not conduct appreciably below that rail voltage — it sits across the line as a high-impedance shunt until a transient exceeds the 396 V minimum breakdown.

DO-201AA axial — board-fit and thermal path

Supplied in the DO-201AA (DO-27) axial-lead package, through-hole mount. Tape & Box packaging suits hand-insertion or selective-wave solder assembly.
