If this part is on your BOM, now is the time to secure lifetime-buy quantities or qualify a drop-in replacement before the window shuts. ## Clamping performance — 1500 W in an axial body The 25.6 V reverse standoff voltage means it sits transparently on a 24 V rail and only starts conducting when the line sees a surge above 28.5 V breakdown. ## Through-hole package — rework-friendly axial lead Housed in a DO-201AA / DO-27 axial leaded package, it's a through-hole part — easy to hand-solder, easy to replace on a rework bench. The axial body handles the thermal pulse of a 1500 W surge without cracking the epoxy, and the leads give a clear visual polarity mark for the cathode band (or lack thereof for bidirectional).","metaTitle":"1.5KE30CA-E3/51 Vishay TVS, 1.5kW Bidirectional","metaDescription":"Vishay 1.5KE30CA-E3/51 TransZorb® TVS, Last Buy status. 1500W peak pulse, 41.4V clamp, bidirectional.
