This makes it suitable for 240 VAC secondary protection or DC bus clamping in industrial power supplies where the transient energy is well-defined. The single unidirectional channel protects one rail; for bidirectional or AC-coupled lines, two devices back-to-back or a dedicated bidirectional TVS would be needed. ## Package and board-fit — DO-214AB (SMC) The 1.5SMC250 comes in the DO-214AB (SMC) surface-mount package, also referenced as SMCJ by some suppliers. Supplied in Tape & Reel packaging, it is ready for automated pick-and-place assembly. The reel quantity is standard for the SMC package size.","metaTitle":"Littelfuse 1.5SMC250 TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC250 Zener TVS diode, 1500W peak pulse, 214V standoff, 361.2V clamp.
