The 1500W rating assumes a 25°C ambient and proper lead-length soldering to a copper trace that sinks the transient heat; derate above 25°C per the datasheet curve. Tape & Reel packaging (TR) suits automated insertion; Cut Tape (CT) is available for prototype or low-volume builds. ## Active lifecycle and sourcing posture No official second-source or pin-compatible cross-reference is published, but the 1.5KE91 family (base number 1.5KE91) shares the same DO-201AE footprint and electrical ratings across the A-suffix variants. ## Temperature range and general-purpose deployment The device is not intended for power-line protection (no internal filter or coordination with mains fuses); it is a general-purpose transient suppressor for DC rails, signal lines, and low-voltage AC secondary circuits.","metaTitle":"Micro Commercial Co 1.5KE91A-TP Zener TVS, 1500W, DO-201AE","metaDescription":"1.5KE91A-TP Zener TVS diode, 1500W peak pulse, 77.8V standoff, 125V clamp, DO-201AE axial.
