With a single bidirectional channel, it protects against both positive and negative transients on the same line — useful for AC-coupled or bipolar signal rails in automotive 12V/24V systems. ## Through-hole axial package and temperature range Housed in a DO-201AA (DO-27) axial-lead through-hole package, it mounts directly into a PCB or terminal block — the 1.5KE body size is standard for this power class.","metaTitle":"Vishay 1.5KE91CAHE3_A/D TVS Diode, 1500W, Bidirectional","metaDescription":"Active Vishay 1.5KE91CAHE3_A/D bidirectional TVS diode, 1500W peak pulse power, AEC-Q101 qualified. 77.8V standoff, 125V clamping.
