The reverse standoff voltage of 154 V means the diode draws negligible leakage current below that DC rail level; the breakdown voltage range starts at 171 V minimum. For a 150 V DC bus or a 120 V AC line after rectification, this part clamps transients before they reach the downstream silicon. ## Package, mounting, and temperature range Housed in a DO-214AB (SMC) surface-mount package, also referenced as SMCJ. The bidirectional configuration means a single device protects both polarities — useful for AC signal lines or DC rails where the polarity could reverse during a fault. The 1.5SMC series includes multiple voltage variants, but the 180CA is the 154 V bidirectional option.","metaTitle":"1.5SMC180CA Littelfuse TVS Diode, 1500W, 154V Standoff","metaDescription":"1.5SMC180CA Littelfuse Zener TVS, 1500W peak pulse, 154V reverse standoff, 246V clamp at 6.2A.
