The 25.6 V reverse standoff voltage means the diode stays off below that rail level; it starts clamping at the 28.5 V minimum breakdown threshold. If your 24 V automotive bus sees load-dump or inductive kickback, this part holds the line before the ECU's input capacitors absorb the remaining energy. ## Automotive qualification and thermal envelope The junction temperature range spans -55°C to 175°C — comfortable for under-hood placement where ambient soaks above 125°C and the TVS self-heats during the pulse. ## Sourcing and lifecycle reality Taiwan Semiconductor continues to manufacture the 1.5KE series in the DO-201 package.","metaTitle":"1.5KE30AHA0G Taiwan Semiconductor Zener TVS, 1.5 kW","metaDescription":"1.5KE30AHA0G automotive Zener TVS diode, 1.5 kW peak pulse, 25.6 V standoff, 41.4 V clamp, DO-201 axial.
