At the rated 5A peak pulse current (IPP at 10/1000µs), the clamping voltage is clamped to 344V maximum. This means a transient exceeding 214V is shunted to ground, and the voltage across the protected load never exceeds 344V under the specified surge condition. ## DO-201AA Axial Package — Through-Hole Integration Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE250AE3/TR13 is a through-hole device intended for point-to-point wiring or PCB mounting with 0.042-inch diameter leads. The CASE-1 supplier device package is the standard Microsemi designation for this body style. The Tape & Reel (TR) packaging option is suited for automated insertion equipment, though the obsolete status means reel quantities are limited to existing surplus inventory. ## Sourcing an Obsolete Part — What to Expect Any functional replacement would require verifying the breakdown voltage, clamping voltage, and package footprint against the original BOM specification.","metaTitle":"Microsemi 1.5KE250AE3/TR13 Zener TVS, 1.5kW, 344V Clamp","metaDescription":"Obsolete Microsemi 1.5KE250AE3/TR13 Zener TVS diode, 1500W peak pulse, 214V standoff, 344V clamp.
