It clamps at 87.1V maximum when conducting 5.7A under the 10/1000µs surge waveform. The 500W peak pulse power rating gives the energy margin needed for industrial power-supply inputs, motor-drive DC buses, or 48V telecom rails.
Lifecycle status is Active — no end-of-life notice, no successor needed. The DO-214AC (SMA) package is a standard JEDEC outline, widely second-sourced across the TVS industry.
The base product number is SMAJ54. Other variants in the SMAJ series share the same DO-214AC footprint and 500W rating but differ in standoff voltage (e.g., SMAJ5.0A, SMAJ12A, SMAJ48A). For a 54V rail, the SMAJ54AE3/TR13 is the specific order code; a direct cross would be another manufacturer's 54V unidirectional TVS in SMA package, such as Littelfuse or Vishay equivalents — verify clamp voltage and breakdown tolerance before substitution.
