SolutionsThe SMCJ18A with 29.2V 20V 18V SMC(DO-214AB) is a Transient Voltage Suppressor (TVS) RoHS produced by SMC Diode Solutions. It is a diode with a reverse breakdown voltage of 20V 18V, a maximum reverse surge capability of 29.2V over a maximum 8/20µs waveform, and a maximum peak pulse power dissipation of 500 Watts. The SMCJ18A is designed to protect sensitive electronic components from electrical overstress caused by transients such as electrostatic discharge (ESD). It offers a fast response time of less than 1.0ns, a low equivalent series resistance (ESR) of 0.33O max, and a maximum clamping voltage of 42.9V. This TVS diode is packaged in a DO-214AB (SMC) form factor and rated for operating temperatures from -55 °C to 150 °C.
