Littelfuse SA5.0A TVS Diode, Unidirectional, 5V, 9.2V, DO-204AC

The Littelfuse SA5.0A is a Transient Voltage Suppressor (TVS) Diode, engineered to protect sensitive electronic circuits from destructive voltage spikes. It features a glass passivated junction for enhanced reliability and offers excellent clamping capability to divert harmful transient energy away from critical components. Its typical failure mode is a short circuit, which can help prevent further damage to the protected system in the event of an over-voltage or over-current condition. With a low incremental surge resistance, it responds efficiently to transient events.

This diode is specifically designed to guard against voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It boasts a robust 500W peak pulse power dissipation capability when tested with a 10/1000μs waveform, ensuring it can handle significant surge events. The device offers an extremely fast response time, reacting to threats in less than 1.0 picosecond from 0 volts to the minimum breakdown voltage.

Constructed with a matte tin, lead-free plated finish, it meets modern environmental standards and is halogen-free. It is capable of withstanding a peak forward surge current of 70A and operates reliably across a wide temperature range from -55°C to +175°C. As an ESD-sensitive device, proper handling precautions are necessary during installation.
