With 30V working voltage and 48.4V maximum clamping voltage at 8.3A peak pulse current, it protects sensitive circuits from ESD, EFT, and surge transients. The bidirectional (CA) configuration provides protection for both positive and negative transients, making it suitable for AC signal lines and automotive bus protection. AEC-Q101 qualified, it operates from -55C to +175C junction temperature.","working_principle":"The SMAJ30CAHE3_A\/I uses avalanche breakdown TVS technology. (1) Normal Operation: When the protected line voltage is within +\/-30V, the TVS presents high impedance with minimal leakage current. (2) Transient Clamping: When a transient exceeds the breakdown voltage (33.3V min), the TVS enters avalanche breakdown, diverting transient current to ground and clamping the voltage to 48.4V maximum. (3) Bidirectional: Two back-to-back Zener diodes provide symmetric clamping for both positive and negative transients. (4) Energy Absorption: The device can absorb up to 400W of peak pulse power during a 10\/1000us transient, protecting downstream components.","pin_description":"
