With a 16 V working voltage and 26.0 V maximum clamping voltage at 23.1 A peak pulse current, it provides robust protection for 12 V automotive systems and 15 V industrial circuits. The bidirectional (CA suffix) configuration clamps transients of both polarities, making it suitable for AC signal lines and applications where reverse voltage events may occur. The SMB (DO-214AA) package is AEC-Q101 qualified and offers sub-nanosecond response time with IEC 61000-4-2 ESD immunity up to \u00b130 kV.","working_principle":"The P6SMB16CA operates as a bidirectional avalanche diode TVS device. Under normal operating conditions, the diode presents a high impedance (leakage current <1 \u00b5A) at voltages below the working voltage (16 V). When a transient voltage exceeds the breakdown voltage (17.8-19.7 V), the device avalanches, creating a low-impedance path that diverts the transient current away from the protected circuit. The clamping voltage is limited to 26.0 V at the rated peak pulse current of 23.1 A, ensuring the protected circuit never sees damaging voltages. In bidirectional configuration, two avalanche diodes are connected in series opposing, providing symmetrical clamping for both positive and negative transients. After the transient subsides, the device returns to its high-impedance off-state automatically.","pin_description":"
