产品概览
The SMCJ54CA is a 1500W bidirectional transient voltage suppressor (TVS) diode in a DO-214AB (SMC) surface-mount package. With 54V standoff voltage, 60V minimum breakdown, and 87.1V maximum clamping voltage at 17.3A, it provides robust protection for 48V power rails and communication lines against lightning and surge transients.
