No official successor or second-source part number is recorded in the lifecycle data. For a BOM line that depends on this TVS, qualifying a functionally equivalent alternative from the same 1.5KE family (same package, similar breakdown voltage) is the prudent hedge — but no pin-compatible drop-in is guaranteed without a board-level review. ## Package and temperature range Housed in a DO-201AE axial-lead package, this TVS is through-hole mounted — the lead bend and body length match the standard DO-201 footprint, so a replacement from another manufacturer in the same package should fit the existing PCB holes. The operating junction temperature range spans -65°C to 175°C, covering industrial and some automotive under-hood environments where the ambient may spike above 125°C.","metaTitle":"Panjit 1.5KE56A_R2_00001 Zener TVS, 1500W, DO-201AE","metaDescription":"Obsolete Panjit 1.5KE56A_R2_00001 Zener TVS diode, 1500W peak pulse, 77V clamping, DO-201AE axial.
