Operating from -55°C to 150°C (TJ), it handles the full industrial temperature range and self-heating during repetitive surges without derating the junction.","metaTitle":"SMAJ78A-13-F TVS Diode, 78V, 400W, DO-214AC","metaDescription":"SMAJ78A-13-F Zener TVS diode, 78V reverse standoff, 126V clamp, 400W peak pulse, DO-214AC.
