The 1.5KE series is a standard JEDEC-registered TVS family, so second-source equivalents from other manufacturers (same DO-201 package, same 36.8 V standoff) exist on the market. Sourced to order against BOM quantities through independent distribution; availability confirmed at RFQ.","metaTitle":"1.5KE43A B0G TVS Diode, 1500W, 36.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE43A B0G unidirectional TVS, 1500W peak pulse, 36.8V reverse standoff, 59.3V clamp, DO-201 axial.
