Supertex inc. Low Voltage Protection Switch Features - - - - - - - - - - Up to ±20V input voltage protection Low on-resistance - 4.5Ω typical Fast switching speed Effectively, a simple two terminal device No external power supplies needed General Description The Supertex FP0030 is a 20V current limiting protection device. It is designed to protect Ethernet systems from high transient voltages. The FP0030 can be considered as a normally closed switch with a typical switch resistance of 4.5Ω. The device starts to turn off when the voltage drop across the two terminals exceeds a nominal value of ±1.5V. In the off state, the FP0030 can withstand up to ±20V across its terminals. A small...
