The breakdown voltage min is 53.2 V, so the device begins conducting just above the nominal rail and clamps before the downstream semiconductors see their abs-max rating. The -55°C to 150°C junction temperature range covers outdoor cabinets and engine-bay electronics without derating the pulse power at the hot end. ## Axial-lead DO-201 package — board-fit and procurement Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE56CA-G mounts through hole — the lead spacing and body diameter match the standard 0.4-inch lead form. The through-hole footprint is forgiving for rework and hand-assembly, and the axial leads carry the pulse current without trace lift-off on a two-layer board. Supplied in Tape & Box (TB) — the TB format is a cut-tape alternative to reel, practical for prototype builds and low-volume production where a full reel MOQ would leave excess inventory. The part is marked with the bidirectional symbol and the breakdown voltage code. ## Active production — no second-source worry The 1.5KE series is a standard JEDEC-registered TVS family with multiple qualified sources (Littelfuse, Vishay, STMicroelectronics all offer pin-compatible 1.5KE56CA parts), so the BOM line is not single-sourced. For a 48 V rail requiring bidirectional clamping, the 1.5KE56CA-G is a drop-in replacement for any 1.5KE56CA from another brand — same DO-201 footprint, same 47.8 V standoff, same 77 V clamp. The Comchip suffix -G indicates RoHS compliance and halogen-free construction.","metaTitle":"Comchip 1.5KE56CA-G TVS, 1.5 kW, 47.8 V, DO-201","metaDescription":"Comchip Technology 1.5KE56CA-G bidirectional Zener TVS, 1500 W peak pulse power, 47.8 V reverse standoff, DO-201AA axial.
