Housed in the DO-214AC (SMA) package, it mounts directly onto a PCB surface — the small footprint suits tight layouts where board space is at a premium, but the junction-to-ambient thermal path relies on the copper pad area under the cathode tab. ## Temperature range and operating envelope The 150°C upper limit means it can sit next to a hot switching regulator or in an outdoor enclosure without derating the pulse capability at elevated ambient — though the peak pulse power curve in the datasheet drops above 25°C, so a 400W transient at 85°C derates to roughly 260W per the standard TVS derating factor.","metaTitle":"SMAJ30A-13 Diodes Inc TVS Diode, 30V, 400W, DO-214AC","metaDescription":"SMAJ30A-13 TVS diode from Diodes Inc, 30V reverse standoff, 400W peak pulse, DO-214AC.
