Once triggered, it clamps the surge to 59.3 V maximum while shunting 25.3 A of peak pulse current. That clamp voltage is the number your downstream silicon sees; if the protected device's absolute-maximum rating is below 59.3 V, this TVS will not protect it. ## DO-201AE axial — through-hole thermal path and board integration The DO-201AE axial package is a through-hole form factor with the cathode band marked on the body. The axial leads conduct surge current and also serve as the primary heat path — the copper pad area on the PCB and the lead length determine the junction-to-ambient thermal resistance. For automated assembly, the part ships on Tape & Reel or Cut Tape. ## Obsolete — sourcing through independent channels Panjit has marked the 1.5KE43A_R2_00001 as obsolete. No official successor order code is recorded. The part is no longer available through standard authorized distribution; supply is limited to surplus and broker inventory. Availability is lot-specific and confirmed at RFQ time. For a new design, a functionally equivalent 1500 W TVS in the same DO-201AE package with a 36 V standoff and unidirectional polarity would be the replacement path — but the exact clamp voltage and breakdown tolerance band must be verified against the BOM requirement.","metaTitle":"Panjit 1.5KE43A_R2_00001 TVS Diode, 1.5kW, 36.8V Standoff","metaDescription":"Panjit 1.5KE43A_R2_00001 Zener TVS, 1500W peak pulse, 36.8V reverse standoff, 59.3V clamp.
