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

The Littelfuse SA5.0A TVS Diode is a unidirectional Transient Voltage Suppressor with a 5V reverse standoff voltage and a 500W peak pulse power rating, designed to protect sensitive electronic circuits from destructive voltage spikes.

Overview

The SA5.0A features a glass passivated junction and provides clamping capability to divert harmful transient energy away from critical components. In the event of an over-voltage or over-current condition, its typical failure mode is a short circuit, which can help prevent further damage to the protected system. It also has a low incremental surge resistance and responds quickly to transient events, reacting in less than 1.0 picosecond from 0 volts to the minimum breakdown voltage.

Key Features

• 500W peak pulse power dissipation when tested with a 10/1000μs waveform
• Peak forward surge current rating of 70A
• Glass passivated junction
• Matte tin, lead-free plated finish
• Halogen-free construction
• Operating temperature range of -55°C to +175°C

Applications

The device is designed to guard against voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). As an ESD-sensitive device, proper handling precautions are necessary during installation.

Specifications

• Reverse standoff voltage: 5V
• Clamping voltage (max): 9.2V
