When a transient exceeds the 14.3 V breakdown threshold, it clamps to 21.2 V maximum while conducting 74 A peak pulse current — this limits the voltage seen by downstream components to a safe level. The 1500 W rating ensures the device absorbs the energy of a single 10/1000 µs surge without failing open or short. The unidirectional channel is polarity-sensitive; reverse-voltage protection requires a second device or a series diode if the line can swing negative. ## Active production and sourcing posture Taiwan Semiconductor Corporation lists the 1.5KE15A A0G as Active in production. For BOM planning, this part is available through authorized and independent distribution channels; current pricing and lead time are confirmed at RFQ against the required quantity.","metaTitle":"1.5KE15A A0G TVS Diode, 1500W, 12.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE15A A0G Zener TVS, 1500W peak pulse, 12.8V reverse standoff, 74A Ipp, DO-201 axial.
