This is a unidirectional Zener TVS — one channel per package, with the cathode identified by the band. It is intended for signal and DC power lines, not AC mains; the 'Power Line Protection: No' spec confirms it should not be used on the line side of a rectifier or transformer.","metaTitle":"Bourns 1.5SMBJ43A-H TVS Diode, 1500W, 43V, AEC-Q101","metaDescription":"Bourns 1.5SMBJ43A-H Zener TVS diode, 1500W peak pulse, 43V standoff, AEC-Q101 automotive.
