SP3118-01ETG Description

Short technical summary and product information.

The Littelfuse SP3118-01ETG is a Zener-type TVS diode designed for general purpose surge protection. It features a reverse standoff voltage of 18V and a clamping voltage of 38V, capable of handling 2A peak pulse current (8/20µs waveform). The diode offers a low capacitance of 0.3pF at 1MHz, making it suitable for high-speed signal lines. The device is bidirectional with a single channel and is not intended for power line protection. It is surface mount packaged in a compact SOD-882 case, operating over a temperature range of -40°C to 125°C. The SP3118-01ETG is RoHS3 compliant and has an MSL of 1 (unlimited).
