SMDJ40CA Description

Short technical summary and product information.

The SMDJ40CA is a bidirectional Zener TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 40V, a maximum clamping voltage of 64.5V, and a peak pulse power dissipation of 3000W (10/1000μs waveform). The device can handle a peak pulse current of 46.5A and offers response times of less than 1ps.

 

This TVS diode is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. It provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The component operates over a junction temperature range of -65°C to 150°C and stores from -65°C to 175°C.

 

The SMDJ40CA is supplied in a DO-214AB (SMC) surface mount package with matte tin lead-free plating. It is halogen free and Pb-free (E3). Thermal characteristics include a junction-to-lead thermal resistance of 15°C/W and junction-to-ambient of 75°C/W, with a maximum power dissipation of 6.5W on an infinite heat sink.
