Low-voltage protection switch

Supertex has introduced the FP0030, a 20 V current limiting protection device ideal for preventing high transient voltages in Ethernet systems.

It starts to turn off when the voltage drop across its two terminals exceeds a nominal value of ±1,5 V and can be considered as a normally closed switch with a typical resistance of 4,5 Ω. In the off state, it can withstand up to ±20 V across its terminals and allow typical current of 700 μA to flow through it.

The FP0030 may also be used as a resettable fuse to protect power lines against output short circuit conditions; its fast switching speed protects the system against abrupt over-current conditions. The IC is available in a three-lead SOT-23 package and is RoHS compliant.
