Additional Details

The SMCJ7.5A/57T features a standoff voltage of 7.5V. When the applied voltage exceeds this level, the TVS diode rapidly conducts, clamping the voltage to a safe level and diverting the excess current away from protected components. The device is packaged in a SMC (DO-214AB) package, which is suitable for surface mounting on printed circuit boards. Consult the Vishay datasheet for specific details on peak pulse power, clamping voltage characteristics, and other pertinent electrical parameters. It operates within a temperature range of -65°C to +150°C.
