Obsolete 1500W Zener TVS — last-time-buy sourcing
The 1.5KE82A-T from Diodes Incorporated is marked Obsolete — the manufacturer no longer produces it. A functional replacement would require evaluating the clamping voltage, breakdown window, and package footprint against the application's protection requirements.
Clamping and breakdown window — 70.1V standoff, 113V clamp
The reverse standoff voltage is 70.1V, 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 threshold.
DO-201 axial package — through-hole board integration
Housed in the DO-201AA / DO-27 axial-lead package, also referred to as the DO-201 supplier device package. The through-hole mounting suits point-to-point wiring, terminal blocks, or PCB layouts where the axial body is inserted and soldered — common in power supply input stages and telecom line cards. The base product number is 1.5KE82, which groups the voltage variants in this 1500W family.
