1500W Zener TVS — 136V standoff, 219V clamp
The 1.5KE160AE3/TR13: Its 136V reverse standoff voltage and 219V clamping point at 6.8A peak pulse current define the protection envelope for a 120V nominal rail — the TVS stays transparent below 136V and clamps transients to 219V before the downstream silicon sees overstress. Packaged in the DO-201AA (DO-27) axial leaded form, it mounts through-hole and handles the full 1500W pulse without derating up to 25°C ambient. The -65°C to 150°C junction temperature range suits equipment exposed to wide thermal swings — outdoor telecom cabinets or industrial control enclosures, for example.
Obsolete — sourcing through independent channels
Microsemi has marked the 1.5KE160AE3/TR13 as Obsolete. No active factory lead time applies. The Tape & Reel packaging (TR suffix) indicates it was originally supplied for automated pick-and-place assembly, though the axial DO-201AA body is typically hand-inserted or formed for through-hole wave solder.
