Datasheet

ProTek Devices has introduced a new ultra-low capacitance (4pF) steering diode/transient voltage suppressor array for circuit protection in various networking applications. Networking application coverage includes Gigabit Ethernet, T1/E1 and T3/E3 (chip-side), and wireless communications. The new device is also suited for USB and DVI interfaces.

This steering diode/TVS array, the PLR2504, provides unidirectional configuration and is rated at 300W peak pulse current (8/20 micro seconds wave shape). ESD protection is more than 25 kilovolts and the component also provides a very low clamping voltage (VC max 12V @ 25A, 8/20 micro seconds).

It protects four I/O ports and a power supply. The PLR2504 is compatible with IEC standards 61000-4-2 (ESD): air ±15kV, contact ±8kV; with 61000-4-4 (EFT): 40A - 5/50ns; and with 61000-4-5 (surge). And, it is RoHS and REACH compliant.

Also, at higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major concern. This device, in conjunction with passive components integrated into a TVS/filter network, can be used for EMI/RFI protection in this scenario.
