Maximum clamping at 143.85 V limits the voltage spike seen by the protected load — the 11.1 A peak pulse current rating (10/1000 µs) confirms the diode can absorb the surge energy without failing short. ## Bidirectional configuration and temperature range A single bidirectional channel protects both polarities — useful on AC signal lines or DC rails where reverse transients are possible, eliminating the need for two diodes back-to-back.","metaTitle":"Littelfuse 1.5KE100C TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE100C bidirectional TVS diode, 1500W peak pulse power, 85.5V standoff, DO-201 axial.
