It is designed to clamp voltage spikes on general-purpose power and signal lines, with a peak pulse power rating of 400 W (10/1000 µs waveform). The device offers a reverse standoff voltage of 130 V and a maximum clamping voltage of 265 V at the peak pulse current of 9 A (8/20 µs). For a 130 V nominal rail, that's roughly twice the operating voltage — typical for a TVS in this class. The breakdown voltage range starts at 144 V minimum, so the device begins conducting before the voltage climbs much above the standoff level. This gives a reasonable protection window for 120 VAC or 130 VDC rails, though the designer should verify the downstream components' voltage rating against the clamp figure. A single bidirectional channel means the SMAJ130CA-TR clamps equally in both directions. That simplifies board layout for AC signal lines, bipolar supplies, or data lines where the polarity isn't fixed. No need to back-to-back two unidirectional devices — one component handles it. The DO-214AC footprint is standard and pick-and-place friendly.","metaTitle":"STMicroelectronics SMAJ130CA-TR TRANSIL TVS","metaDescription":"STMicroelectronics SMAJ130CA-TR TRANSIL bidirectional TVS diode. 400W peak pulse power, 130V standoff, 265V clamping.

SMAJ130CA-TR is the bidirectional variant. They share the same peak pulse power (400 W), breakdown voltage range, and DO-214AC package, but the SMAJ130A clamps only one polarity. Choose the unidirectional version if your circuit has a fixed polarity and you need slightly lower clamping; the bidirectional version handles both polarities in one component."},{"question":"What is the lead time for SMAJ130CA-TR?","answer":"As an active STMicroelectronics part, it is generally available through distribution channels.
