The 54V reverse standoff voltage (VRWM) is the DC operating level where the diode is effectively an open circuit — below this threshold it does not conduct. For a 48V automotive bus or a 54V telecom supply, this part sits just above the rail voltage, so it does not clip normal operation but triggers fast when a surge exceeds the breakdown voltage (60V minimum).","metaTitle":"Bourns 1.5SMBJ54A TVS Diode, 1500W, 54V, DO-214AA","metaDescription":"Bourns 1.5SMBJ54A AEC-Q101 Zener TVS diode, 1500W peak pulse power, 54V reverse standoff, 87.1V clamping.
