The reverse standoff voltage of 7V means the diode does not conduct at normal operating levels up to that point; above it, breakdown begins at a minimum of 7.78V. This gives a narrow guard band for a 5V or 3.3V rail but is sized for a 7V bus where the operating margin is tight. ## Package and temperature envelope Housed in the industry-standard DO-214AC (SMA) package, the SMAJ7.0A-13 is a surface-mount device suited for automated pick-and-place assembly. The SMA footprint is common across many TVS families, so the PCB layout is interchangeable with other SMA-packaged parts from the same class. The operating junction temperature range spans -55°C to 150°C, covering industrial and some automotive under-hood environments. The wide temperature window means the clamping voltage and leakage current remain within datasheet limits across the full range, not just at 25°C.","metaTitle":"SMAJ7.0A-13 TVS Diode, 400W, 7V Standoff, DO-214AC","metaDescription":"Diodes Incorporated SMAJ7.0A-13 Zener TVS, 400W peak pulse, 7V reverse standoff, 12V clamping at 33.3A.
