The 1500 W rating is a peak number; continuous power dissipation is limited by the package and ambient temperature, so derating is needed in high-duty-cycle applications. ## Active production — sourcing and compliance Littelfuse lists the 1.5KE24CA as Active in its product portfolio. The 1.5KE series is a long-running TVS diode family with broad industry acceptance. Compliance documentation including RoHS and REACH declarations is available from Littelfuse for this part number — the tape-and-reel and cut-tape packaging options cover both prototyping and production volumes.","metaTitle":"Littelfuse 1.5KE24CA TVS Diode, 1500W, 33.2V Clamp, DO-201","metaDescription":"Littelfuse 1.5KE24CA bidirectional TVS diode, 1500W peak pulse power, 33.2V clamping at 45.8A.
