Product Description
The Littelfuse SMCJ350A Uni-Directional TVS Diode is a high-performance semiconductor component engineered to safeguard electronic circuits against transient voltage events such as lightning surges and switching spikes. Featuring a single-element, uni-directional configuration, this diode delivers precise and rapid clamping action, minimizing the risk of damage to sensitive equipment.
With a peak pulse power dissipation of 1.5 kW and a maximum reverse stand-off voltage rated at 350 V, the SMCJ350A is capable of supporting robust transient protection applications on modern PCB assemblies. The surface mount DO-214 package, with dimensions of 7.11 mm length, 6.22 mm width, and 2.41 mm height, is engineered for space efficiency and low profile demand.
This TVS diode offers a minimum breakdown voltage of 391 V while maintaining a clamping voltage of 567 V and a peak pulse current of up to 2.6 A. It is suitable for environments requiring reliable performance from -65°C to 150°C. Enhanced with built-in strain relief and a glass passivated junction, the diode ensures greater durability and low inductance characteristics.
The SMCJ series is halogen-free and designed for surface mounting, optimizing board layout and supporting high-temperature soldering up to 250°C for 10 seconds at terminals. Excellent clamping capability and a fast response time of typically less than 1.0 picosecond guarantee swift transition from 0 Volts to minimum breakdown voltage, ensuring superior protection.
Typical applications include industrial automation, communications systems, consumer electronics, laboratory instrumentation, and manufacturing equipment where transient voltage suppression is critical. The diode supports ESD protection and is ideal for designing circuits requiring high current surges and efficient voltage control.
In summary, this Littelfuse SMCJ350A TVS diode is recommended for engineers seeking advanced, reliable protection for circuit boards and sensitive electronic systems in commercial, industrial, and laboratory environments.
