SP03A-3.3BTG Description

Short technical summary and product information.

The Littelfuse SP03A-3.3BTG is a steering (rail-to-rail) TVS diode designed for Ethernet applications. It provides bidirectional protection for two unidirectional channels, with a reverse standoff voltage of 3.3V and a maximum clamping voltage of 18V at 150A peak pulse current (8/20µs waveform). The device is rated for 3.3kW peak pulse power, ensuring robust protection against transient overvoltages.

 

This TVS diode features a low capacitance of 16pF typical at 1MHz, making it suitable for high-speed data lines. It offers power line protection and is designed for surface mount assembly in an 8-SOIC (0.154", 3.90mm width) package. The operating temperature range is -40°C to 125°C (junction).

 

The SP03A-3.3BTG is ideal for protecting Ethernet interfaces from electrostatic discharge (ESD) and other transients. Its compact SOIC package facilitates space-constrained designs while providing reliable circuit protection.
