The 1500W peak pulse rating is tested with a 10/1000 µs waveform — a standard telecom surge shape. For shorter pulses (8/20 µs), the peak power capability is higher; for longer transients, derate accordingly. ## Sourcing an EOL part for a production BOM This part is available through independent surplus and broker channels, sourced to order against an RFQ. Availability and date-code provenance are confirmed at quote time — every lot is traceable back to the manufacturer's original production. For a new design, a current-production TVS from the same 1.5KE family (e.g., the 1.5KE91CA series in a non-EOL suffix) should be evaluated, but the bidirectional, 77.8V standoff, and 1500W rating must be matched exactly to maintain the same protection profile.","metaTitle":"Microsemi 1.5KE91CAE3/TR13 TVS Diode, 1.5kW, 77.8V Standoff","metaDescription":"Obsolete 1.5KE91CAE3/TR13 Zener TVS diode, 1500W peak pulse, 77.8V standoff, 125V clamping.
