At the 14.6 A peak-pulse current, the clamping voltage reaches 103 V maximum. That 103 V ceiling is what the downstream silicon sees; if the protected rail is a 64.1 V supply, the TVS holds the transient 39 V above the rail, which is the margin the downstream MOSFET or IC must survive. The reverse standoff voltage is 64.1 V, and breakdown starts at 71.3 V minimum. In normal operation the part is effectively open; it only conducts when the transient exceeds the breakdown knee. The 64.1 V standoff means this TVS fits a 48 V or 60 V nominal rail with margin for steady-state tolerance. ## Unidirectional, axial, through-hole Single unidirectional channel — cathode band on the DO-201AA / DO-27 axial body. The through-hole mounting suits point-to-point wiring on terminal strips or PCB layouts where the lead bend absorbs thermal expansion. The Tape & Reel packaging is unusual for an axial part — it suggests the original customer ran automated insertion; for manual or low-volume builds, the reel can be cut, but the lead form is set for machine feed. Junction temperature range spans -65°C to +150°C — the full military-grade band. No power-line protection, so this is a signal-rail or low-side supply clamp, not a mains-side suppressor.","metaTitle":"Microsemi 1.5KE75AE3/TR13 TVS, 1500W, 103V Clamp, Axial","metaDescription":"Obsolete Microsemi 1.5KE75AE3/TR13 Zener TVS, 1500W peak pulse, 103V clamping at 14.6A.
