SMDJ17CA

The SMDJ17CA is a bidirectional transient voltage suppression (TVS) diode from the SMDJ series by Littelfuse. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. This component offers a peak pulse power dissipation of 3000W for a 10/1000µs waveform, with a reverse standoff voltage of 17V and a maximum clamping voltage of 27.6V. The minimum breakdown voltage is 18.9V, and the peak pulse current rating is 108.7A.

Electrical characteristics include a typical response time of less than 1 picosecond, making it suitable for fast transient protection. The device operates over a junction temperature range of -65°C to 150°C, with a storage temperature range of -65°C to 175°C. Typical thermal resistance is 15°C/W junction-to-lead and 75°C/W junction-to-ambient. The maximum forward surge current (8.3ms) is 300A, and forward voltage is 3.5V for single die or 5.0V for stacked die configurations.

The SMDJ17CA is available in a surface mount DO-214AB (SMC) package, with matte tin lead-free plating. It is suitable for general purpose applications, including I/O interfaces, VCC bus protection, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The component is halogen free and lead-free (Pb-free E3).
