Zener TVS for 30.8 V rails — 1500 W pulse rating and obsolete status
The 1.5KE36AE3/TR13: The reverse standoff voltage of 30.8 V means this part sits across a 24 V or 28 V bus without conducting during normal operation; the breakdown voltage range starts at 34.2 V min. Peak pulse current is 30 A at the clamping limit, which defines the maximum surge the diode can handle in a single event.
Lifecycle: obsolete — last-time-buy window closed
Microsemi has marked the 1.5KE36AE3/TR13 as Obsolete, meaning the manufacturer no longer produces this exact part number. For existing BOM lines that already specify this order code, sourcing is limited to independent distribution channels.
Package and thermal environment
Housed in a DO-201AA (DO-27) axial-lead package, the part is Through Hole mounted — suitable for point-to-point wiring or PCB through-hole layouts where the lead bend radius and body clearance are known. The operating junction temperature range spans -65 °C to 150 °C, covering military/aerospace ambient extremes as well as industrial enclosure environments. The Tape & Reel (TR) packaging option indicates this variant was originally intended for automated assembly; however, given the obsolete status, procurement will likely be from surplus reels or cut tape rather than fresh factory production.
