Clamping is specified at 72.7V maximum at the 5.5A peak pulse current (10/1000µs waveform), so a 45V bus sees the surge clipped to under 73V before the TVS absorbs the energy — the 400W rating is the product of the clamp voltage and the peak current under that waveform. ## Package and board-fit for automated assembly Housed in the standard DO-214AC (SMA) surface-mount package with a supplier device package designation of SMA — the footprint matches the common SMA pad layout used across the industry, so no board respin is needed if replacing an existing SMA TVS.","metaTitle":"Diodes Inc SMAJ45CA-13 TVS Diode, 400W, 45V, DO-214AC","metaDescription":"SMAJ45CA-13 bidirectional TVS diode, 400W peak pulse, 45V standoff, 72.7V clamp.
