Bidirectional clamping means a single device protects both polarities on a signal or power line — useful for AC-coupled data lines or battery-reversal scenarios where the TVS sees voltage in either direction.","metaTitle":"TSC 1.5KE20CH TVS Diode, 1.5kW, 16.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE20CH bidirectional Zener TVS, 1500W peak pulse, AEC-Q101 automotive grade, 29.1V clamp, DO-201 axial.
