1.5 kW peak pulse, 56 V bidirectional Zener TVS
The 1.5KE56CA_R2_00001: The single bidirectional channel means the same device protects against positive and negative transients, simplifying BOM and layout for symmetrical rail protection.
DO-201AE axial through-hole package
The operating junction temperature range spans -65°C to 175°C, allowing deployment in high-temperature environments such as industrial power supplies or automotive under-hood modules.
Obsolete — sourcing through independent channels
Available through independent surplus and broker channels. No official successor or pin-compatible cross-reference is recorded from Panjit. For new designs, consider a current-production bidirectional TVS in the same DO-201AE footprint with equivalent standoff and clamping voltages.
