The 1500 W rating at 25°C derates with ambient — at 125°C the power capability drops to roughly 60 % of the 25°C figure, so a design running near the thermal limit should budget the derating. ## Lifecycle and supply posture The 1.5KE series is a standard JEDEC DO-201 footprint, so parametric equivalents from other brands (same 1500 W, 18.8 V standoff, DO-201 package) can be qualified as alternates to avoid single-source exposure.","metaTitle":"1.5KE22A A0G TVS Diode, 1500W, 18.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE22A A0G Zener TVS, 1500W peak pulse, 18.8V standoff, 30.6V clamp, DO-201 axial.
