The junction operates from -55 °C to +150 °C, covering the full industrial temperature range — the peak power derating curve starts above 25 °C, so a 1500 W rating at room temperature drops linearly to zero at 150 °C. For a 1.5 kW pulse at 85 °C ambient, budget roughly 60 % of the rated power.","metaTitle":"Bourns 1.5SMBJ30CA TVS Diode, 1.5kW, 30V, DO-214AA","metaDescription":"Bourns 1.5SMBJ30CA bidirectional TVS, 1500W peak pulse power, 30V standoff, 33.3V breakdown, DO-214AA SMB.
