The junction temperature rating is what matters for the clamping performance under a transient — the device self-heats during the event, and 150°C TJ maximum is the derating ceiling that sets your worst-case thermal budget.","metaTitle":"Bourns 1.5SMC56CA-Q TVS Diode, 77V Clamping","metaDescription":"Bourns 1.5SMC56CA-Q bidirectional TVS Zener, 1500W peak pulse, 77V clamping, AEC-Q101.
