The through-hole DO-201AA (DO-27 axial) package suits point-to-point wiring on terminal blocks or PCB mounting with lead bending. The -65°C to 150°C junction temperature range covers most outdoor and engine-bay environments without derating. ## Ratings that decide the fit Reverse standoff voltage is 5.8V typical — the rail must stay below this during normal operation. Breakdown occurs at 6.45V minimum, so a 5V supply with ±10% tolerance (5.5V max) still leaves margin before the TVS starts conducting leakage current. Clamping at 10.5V means a downstream device rated for 12V abs-max sees a peak well within its safe operating area. The 143A peak pulse current (10/1000µs) handles short-duration surges from nearby lightning strikes or capacitive discharge; for repetitive events the average power dissipation must be calculated from the duty cycle. No power line protection (no internal filter) — this is a pure transient clamp for signal or low-power DC buses, not for AC mains input. ## Obsolete — sourcing through independent channels Microsemi lists this part as obsolete. No official successor is recorded, so new designs should consider alternative TVS diodes from the same 1.5KE family with similar clamping and standoff ratings, or from other manufacturers with DO-201 packages. Available through independent surplus and broker channels. For volume requirements the buyer should request a quote with target lead time.","metaTitle":"1.5KE6.8AE3/TR13 Microsemi TVS, 1500W, 5.8V Standoff","metaDescription":"Microsemi 1.5KE6.8AE3/TR13 Zener TVS, 1500W peak pulse, 5.8V standoff, DO-201AA axial.
