LITTELFUSE SMAJ 5V Unidirectional TVS Diode, DO-214AC

The LITTELFUSE SMAJ series Transient Voltage Suppression (TVS) Diode is a surface-mount component engineered to protect sensitive electronic circuits from damaging voltage spikes. These transients can be induced by lightning, electrostatic discharge (ESD), or other electrical disturbances. This unidirectional model is specifically designed to safeguard I/O interfaces, VCC bus lines, and other vulnerable points in electronic designs, ensuring the longevity and reliability of your equipment.

Featuring a robust 400W peak pulse power capability (tested with a 10x1000μs waveform), this diode offers excellent clamping performance to swiftly divert excess energy away from critical components. Its glass passivated junction and low-inductance design contribute to reliable operation and a fast response time of less than 1 picosecond from 0V to the breakdown voltage. The component is compliant with key international standards for ESD (IEC 61000-4-2) and Electrical Fast Transient (EFT) protection (IEC 61000-4-4), making it a trusted choice for robust circuit protection.

With an operating temperature range from -65°C to 150°C, this TVS diode is suitable for use in demanding environments. Its compact DO-214AC (SMA) surface-mount package is ideal for optimising PCB space in modern, high-density electronic assemblies. This makes it a fundamental component for enhancing the electromagnetic compatibility (EMC) and surge resilience of a wide array of electronic products.
