Zener TVS diode — 1500 W peak pulse, 154 V standoff, axial DO-201AA
The 1.5KE180AE3/TR13: The breakdown voltage range starts at 171 V minimum, ensuring the device remains transparent below the normal operating rail and only conducts during fault events.
Where it fits — signal and DC rail transient suppression
This TVS is intended for general-purpose transient protection applications, not for AC mains power line protection — the absence of a power line protection rating means it is best suited for DC power buses, telecom lines, or industrial signal interfaces where the steady-state voltage stays below 154 V. The through-hole DO-201AA / DO-27 axial package (supplier device package CASE-1) mounts into a standard 0.040-inch diameter lead hole and is wave-solder compatible, making it a straightforward retrofit in existing board layouts or point-to-point wiring.
Lifecycle reality — obsolete, sourced through independent channels
No official successor order code is recorded from Microsemi. Sourcing is limited to independent surplus and broker inventory; lots are verified for authenticity and traceability at the time of RFQ.
