Obsolete — last-time-buy sourcing for existing BOM lines
The 1.5KE440CA-E3/73: For existing BOM positions that require this exact order code, supply is available through independent distribution channels.
1.5 kW peak pulse, 376 V standoff — TransZorb TVS diode
The 602 V clamping ceiling means this device limits a surge to a voltage the downstream 600 V-class semiconductors can survive — a typical design margin for 400 VAC rail transients in industrial power supplies.
DO-201AA axial package, -55 to 175 °C range
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE440CA-/73 is a through-hole device suited for point-to-point wiring or PCB mounting where the lead bend radius is controlled to avoid stress on the glass passivation.
