600W bidirectional TVS for 54V rails
It clamps transients at 87.1V maximum, protecting downstream circuitry on 48V to 54V rails. A single bidirectional channel means no polarity worries — it suppresses both positive and negative surges on the same line, which simplifies bill-of-materials layout for AC-coupled or bipolar signal lines.
Clamping voltage and pulse current
At the 6.9A peak pulse current (10/1000µs), the clamping voltage holds at 87.1V max. That margin above the 60V minimum breakdown voltage gives a 27V window for the TVS to absorb the surge before the protected circuit sees overstress.
The DO-214AA SMB package is widely used, so tape-and-reel quantities (TR suffix) are the standard procurement format for pick-and-place assembly. No stock-holding claim; we confirm availability and current pricing at quote time.
The DO-214AA (SMB) body is a low-profile, two-terminal package with a visible cathode band on the unidirectional variant — but this bidirectional part has no polarity mark, so orientation is non-critical. The SMB footprint is large enough to hand-rework with a standard hot-air station without lifting adjacent passives. Surface-mount assembly; the solder pad layout per JEDEC standard ensures consistent thermal coupling to the PCB copper for heat sinking during the pulse event.
