The single bidirectional channel handles surge currents up to 112 A peak pulse (Ipp at 10/1000 µs), making it suitable for general-purpose overvoltage protection on signal or power rails where the operating voltage stays below 7.78 V. ## Package, temperature range, and board-fit Housed in a DO-201AE axial-lead through-hole package (supplier device package DO-201AE), it mounts into a standard 0.100-inch pitch hole pattern. No power line protection feature is built in — this is a discrete TVS, not a filtered protector. ## Sourcing an obsolete part — what to expect Panjit lists the 1.5KE9.1CA_R2_00001 as obsolete. A board-spin to a different package or a different standoff voltage would require requalification.","metaTitle":"Panjit 1.5KE9.1CA_R2_00001 TVS, 1500W, 7.78V Standoff","metaDescription":"Panjit 1.5KE9.1CA_R2_00001 bidirectional Zener TVS, 1500W peak pulse, 7.78V standoff, 13.4V clamp, DO-201AE.
