The 42.35 V minimum breakdown ensures the device does not conduct at the standoff voltage, avoiding leakage-induced heating. The single bidirectional channel protects both polarities in one package — useful on AC signal lines or DC rails where reverse-voltage events are possible.","metaTitle":"Littelfuse 1.5KE47C TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE47C Zener TVS diode, 1500W peak pulse power, bidirectional, DO-201 axial.
