The SMCJ18CA is a bidirectional transient voltage suppression (TVS) diode from Littelfuse, part of the SMCJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.
Key electrical specifications include a reverse standoff voltage of 18V, a clamping voltage of 29.2V at the peak pulse current of 51.4A, and a peak pulse power dissipation of 1500W (10/1000μs waveform). The device offers a fast response time of less than 1.0ps and low incremental surge resistance.
The SMCJ18CA is housed in a surface-mount DO-214AB (SMC) package with matte tin lead-free plating. It supports an operating temperature range of -55°C to 150°C and is rated for MSL level 1 per J-STD-020. The part is halogen free and RoHS compliant.
The reverse standoff voltage (Vrwm) is 18V.
The clamping voltage is 29.2V at the peak pulse current of 51.4A.
The peak pulse power dissipation is 1500W (1.5kW) for a 10/1000μs waveform.
The SMCJ18CA is available in a surface mount DO-214AB (SMC) package.
The datasheet states the SMCJ18CA is halogen free and RoHS compliant, with Pb-free E3 terminal finish.
