The bidirectional design means it clamps equally for positive and negative transients — useful on AC-coupled or bipolar signal lines where polarity is unpredictable.","metaTitle":"YAGEO 1.5KE250CA-AT/B TVS Diode, 1500W, AEC-Q101","metaDescription":"YAGEO 1.5KE250CA-AT/B bidirectional Zener TVS diode, 1500W peak pulse, 214V standoff, DO-201AA axial, AEC-Q101 qualified.
