The breakdown voltage starts at 16.7 V minimum, and the reverse standoff is 15 V, which leaves a 1.7 V guard band before the TVS begins conducting on a nominal 15 V supply.","metaTitle":"SMBJ15CA-TR TVS Diode, 600W Bidirectional, DO-214AA","metaDescription":"STMicroelectronics SMBJ15CA-TR bidirectional TVS diode. 600W peak pulse power, 24.4V clamping, 15V standoff.
