SMDJ24CA

The SMDJ24CA is a bidirectional transient voltage suppression (TVS) diode from Littelfuse Inc. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. This device features a reverse standoff voltage of 24V and a maximum clamping voltage of 38.9V at a peak pulse current of 77.1A (10/1000µs waveform). With a peak pulse power dissipation of 3000W, it offers robust protection for a variety of applications.

Key electrical characteristics include a breakdown voltage range of 26.7V to 29.5V, a maximum reverse leakage current of 2µA at Vrwm, and a fast response time of less than 1ps. The device also provides ESD protection of 30kV air and contact per IEC 61000-4-2. The operating junction temperature range is -65°C to 150°C, with storage temperature up to 175°C.

The SMDJ24CA is housed in a DO-214AB (SMC) surface mount package with matte tin lead-free termination. It is suitable for automated assembly and is halogen-free and lead-free (Pb-free E3). The device is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited). Typical thermal resistance is 15°C/W junction-to-lead and 75°C/W junction-to-ambient.

This TVS diode is ideal for general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. It is a bidirectional device, making it suitable for AC or bidirectional signal lines.
