New steering diode/TVS array for circuit protection in networking
ProTek Devices has a new ultra-low capacitance (4pF) steering diode/transient voltage suppressor array for circuit protection in multiple networking applications. Networking application coverage includes Gigabit Ethernet, T1/E1 and T3/E3 (chip-side), and wireless communications. This new device is also ideal for USB and DVI interfaces.
This device – the PLR2504– provides unidirectional configuration and is rated at 300W peak pulse current (8/20 micro seconds wave shape). ESD protection is > 25 kilovolts and the component also offers a very low clamping voltage (VC max 12V @ 25A, 8/20 micro seconds). It protects four I/O ports and a power supply. The device 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). It is also RoHS and REACH compliant. Higher operating frequencies or faster edge rates, insertion loss and signal integrity are also an important concern. In conjunction with passive components integrated into a TVS / filter network, this device can be used for EMI/RFI protection in this scenario.
The device is offered in a moulded JEDEC DFN-10 package weighing only approximately seven milligrams. Other important mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin - Sn, 100) 260C to 270C. The device has a flammability rating of UL 94V-0.
