SP4023-01FTG Description

Short technical summary and product information.

The SP4023-01FTG is a unidirectional TVS diode from Littelfuse Inc., designed for steering (rail-to-rail) protection in automotive applications. It features a reverse standoff voltage of 15V and a clamping voltage of 40V, capable of handling 12A peak pulse current (8/20µs) and 450W peak pulse power. With a low capacitance of 1.3pF at 1MHz, it is suitable for high-speed signal line protection without significant signal degradation.

 

This device operates over a wide temperature range of -40°C to 125°C, making it reliable in harsh environments. It is not intended for power line protection, as indicated by its power line protection specification of 'No'. The SP4023-01FTG is packaged in a surface-mount SOD-323 (SC-76) package, enabling compact PCB designs. Its automotive-grade design ensures robust performance in vehicle electronics.
