The bidirectional configuration (single channel) means it clamps both positive and negative transients symmetrically, so orientation on the PCB is non-critical — useful for AC-coupled signal lines or floating supplies. ## Package and temperature range The SMC footprint is standard for 1.5kW TVS diodes; the wide temperature range covers industrial and telecom enclosure environments without derating at the high end. ## Active production and sourcing It is a standard catalog TVS diode in the 1.5SMC family, with no announced end-of-life or last-time-buy.","metaTitle":"Littelfuse 1.5SMC300CA TVS Diode, 1.5kW, 414V Clamp","metaDescription":"Littelfuse 1.5SMC300CA bidirectional Zener TVS, 1500W peak pulse, 256V standoff, 414V clamp.
