The single unidirectional channel is polarity-sensitive — the cathode band on the DO-214AB SMC package must face the positive rail. Power line protection is not provided, so this device is intended for signal or low-power supply lines, not for direct mains or high-current bus clamping.","metaTitle":"Bourns 1.5SMC43A-Q TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"Bourns 1.5SMC43A-Q Zener TVS, 1500W peak pulse, 36.8V standoff, AEC-Q101 qualified.
