Product Description
Littelfuse SMCJ28A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components in semiconductor circuits from transient voltage spikes. With a peak pulse power dissipation rating of 1.5 kW, this diode provides robust protection against electrical surges induced by lightning and other transient voltage events.
The SMCJ28A diode features a single diode configuration housed in a compact 2-pin DO-214 surface mount package, minimizing board space while ensuring effective protection performance. Its minimum breakdown voltage is 31.1 V, and it clamps transient voltage at 45.4 V, effectively safeguarding the circuit during surge conditions.
Capable of operating in extreme temperatures from -65°C to 150°C, the diode maintains reliable protection under harsh environmental conditions. The device offers electrostatic discharge (ESD) protection and features a low maximum reverse stand-off voltage of 28 V with minimal leakage current, enhancing circuit stability and efficiency.
Designed for industrial and electronic applications, the SMCJ28A diode is halogen free and incorporates a glass passivated junction for long-term reliability. It supports high temperature soldering up to 250°C for 10 seconds at terminals, facilitating strong mechanical and electrical connection during PCB assembly.
Applications include protection of semiconductors in power and electronic connectors, discrete semiconductors modules, and other sensitive electronic components in industrial, laboratory, telecommunications, automotive, and consumer electronics sectors.
