That 500W rating is the headline number for transient protection: it tells you how much energy the part can absorb before the junction gives way. Minimum breakdown voltage is 60V, with a reverse standoff of 54V — meaning the part stays transparent on a nominal 48V or 54V bus and only starts conducting when the line rises above 60V. Clamping voltage is 96.3V max at the rated 5.2A peak pulse current. That 42V headroom between standoff and clamp is the margin the downstream silicon sees; if the load can survive a 96V transient, this part fits. ## Active production, DO-214AC package on reel Sourced to order against RFQ — we confirm availability and current pricing at quote time.","metaTitle":"SMAJ54E3/TR13 Zener TVS – 54V, 500W, DO-214AC (SMA)","metaDescription":"SMAJ54E3/TR13 Zener TVS from Microchip: 54V reverse standoff, 500W peak pulse power, DO-214AC (SMA) package, active production.
