The SP4021-01FTG-C is a bidirectional TVS diode from Littelfuse Inc. designed for protecting sensitive electronics from voltage transients. It features a reverse standoff voltage of 5 V and a typical clamping voltage of 19.6 V under an 8/20 µs pulse condition. The device can handle a peak pulse current of 24 A (8/20 µs) and offers a peak pulse power dissipation of 600 W.
This TVS diode is configured as a steering (rail-to-rail) protector with a single bidirectional channel. It is specifically intended for Ethernet applications and does not provide power line protection. The component is surface mount packaged in a SOD-323 case (SC-76), making it suitable for compact PCB designs.
The SP4021-01FTG-C operates over a junction temperature range of -40°C to 125°C. Its low typical capacitance of 2.5 pF at 1 MHz makes it well-suited for high-speed data line protection without significant signal degradation.
