Additional Details

The SMDJ110CA is a surface-mount device with a DO-214AB (SMC) package. It has a clamping voltage of approximately 154V at a peak pulse current of 39A. The device operates over a wide temperature range, typically from -55°C to +150°C. It is crucial to select the appropriate TVS diode based on the specific voltage and current requirements of the application. The bi-directional configuration makes it suitable for AC applications, while the uni-directional version is suitable for DC applications. The fast response time ensures that the transient voltage is suppressed quickly, preventing damage to sensitive components. Littelfuse offers comprehensive datasheets and application notes to aid in the selection and implementation of TVS diodes.
