Product Description
Littelfuse SMCJ40CA is a high-performance 1-element bi-directional transient voltage suppression (TVS) diode designed for protecting electronic circuits from voltage transients. It features a peak pulse power dissipation of 1.5 kW in a compact surface mount DO-214 package, ideal for optimizing board space in modern electronics.
This diode is configured as a single element with two pins and supports a minimum breakdown voltage of 44.4 V and a maximum reverse stand-off voltage of 40 V, ensuring excellent voltage clamping capabilities with a clamping voltage of 64.5 V. Its operational temperature range from -65°C to 150°C enables reliable performance in harsh environments.
The SMCJ40CA offers peak pulse currents up to 23.3 A and incorporates a glass passivated junction along with a halogen-free design, promoting durability and environmental safety. Its fast response time, typically less than 1 picosecond from 0 volts to minimum breakdown voltage, provides rapid suppression of voltage spikes caused by lightning and other transient events.
Additional features include low incremental surge resistance, low inductance, high temperature soldering tolerance at 250°C for 10 seconds at terminals, and a repetition duty cycle of 0.05%. These make it highly suitable for industrial, commercial, and automotive applications where transient voltage protection is critical.
This diode is particularly recommended for protecting sensitive semiconductor devices in telecommunications, power supplies, industrial controls, and consumer electronics. Its bi-directional capability allows effective protection on both positive and negative transient voltage events, enhancing resilience of electronic systems.
