The -55°C to 150°C junction temperature range covers the full automotive under-hood ambient, including the hot-soak condition after engine shutdown where under-bonnet temperatures peak. The junction rating is the absolute ceiling — the board's copper pour and via count under the cathode tab determine the actual derating above 25°C. ## Bidirectional — one part protects both polarities A single bidirectional channel means the 1.5SMBJ13CA-H clamps positive and negative transients symmetrically — useful on AC-coupled signal lines or on DC buses where reverse-voltage events (reverse battery, alternator field decay) are as likely as overvoltage.","metaTitle":"Bourns 1.5SMBJ13CA-H TVS Diode, 1500W, 13V, DO-214AA","metaDescription":"Bourns 1.5SMBJ13CA-H bidirectional Zener TVS, 1500W peak pulse power, 13V reverse standoff, AEC-Q101 qualified.
