Bidirectional means a single part clamps both polarities — useful on AC-coupled signal lines or DC rails where the transient can swing positive or negative relative to ground. The DO-214AB (SMC) body is larger than the smaller SMA/SMB siblings, which means the copper pad on the PCB carries the heat from repeated pulses — the datasheet's thermal impedance curve assumes a 1 oz copper land pattern.","metaTitle":"Vishay 1.5SMC43CA-E3/57T TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC43CA-E3/57T bidirectional TVS diode, 1500W peak pulse power, 36.8V standoff, 59.3V clamp, DO-214AB (SMC).
