With a 45 V reverse standoff voltage and a minimum breakdown of 50 V, this part sits on a 45 V nominal rail — 48 V telecom buses, 36-48 V industrial supplies, or 42 V automotive systems — and begins conducting when the transient exceeds the breakdown threshold. No last-time-buy window, no NRND flag, no successor to track. For a BOM cost engineer or allocation watcher, this means the part is still in the franchised channel and the spot market is not yet driven by scarcity — the usual allocation signals (extended lead times, premium-only availability) do not apply here today. ## What the ratings mean for the board The 400 W peak pulse power rating is the device's ability to absorb a single 10/1000 µs surge without failing. The 72.7 V clamping voltage tells the layout engineer the maximum voltage the protected IC will see across the TVS during that event — if the downstream device's abs-max rating is below 72.7 V, this clamp is not enough and a higher-power or lower-clamp part is needed. The DO-214AC (SMA) package is a standard two-lead footprint with a 0.065-inch (1.65 mm) lead pitch. Reflow profile follows the standard JEDEC MSL-1 moisture sensitivity for this package — no bake required before assembly if the shelf life has been respected. The bidirectional channel means a single device protects both positive and negative transients on the same rail — useful for AC-coupled lines or bipolar supplies where polarity is not fixed. ## Sourcing posture for this line item Available through independent and franchised distribution channels. No single-source risk — the SMAJ45CA is a standard JEDEC-registered part number produced by multiple manufacturers, so a second-source cross-reference is straightforward for a buyer managing allocation risk.","metaTitle":"Diodes Inc SMAJ45CA-13-F TVS Diode, 400W, Bidirectional","metaDescription":"SMAJ45CA-13-F bidirectional TVS diode, 45V standoff, 72.7V clamp, 400W peak pulse, DO-214AC (SMA).
