The DO-201 footprint is standard for 1.5 kW TVS diodes — the axial body and lead diameter handle the pulse current without trace lift-off, and the through-hole joint provides a lower thermal resistance path to the board copper than a surface-mount equivalent. Littelfuse lists the 1.5KE250-B as obsolete. No official successor order code is recorded. Sourcing is through independent distribution — quantities are confirmed at RFQ, and the available stock is typically surplus or new-old-stock from authorized channels.","metaTitle":"Littelfuse 1.5KE250-B Zener TVS, 1.5kW, 214V Standoff","metaDescription":"Littelfuse 1.5KE250-B Zener TVS diode, 1500W peak pulse power, 214V reverse standoff, DO-201 package.
