A TVS array family with low capacitance launched by ProTek Devices provides circuit protection in smartphones, other handheld wireless systems, USB interfaces and Ethernet 10/100/1000 Base T applications.

The GBLCxxHP/CHP TVS array series comprises of two devices, the GBLC03HP and GBLC03CHP, with a rated stand-off voltages of 3.3V, and the GBLC05HP and GBLC05CHP with a rated stand-off voltages of 5.0V. They are available in both unidirectional and bidirectional configurations and are rated at 750W for an 8/20 microsecond waveshape. The series has a capacitance of 3pF (typical) and leakage current of less than 0.5μA.

The GBLCxxHP/CHP series is compatible with IEC standards 61000-4-2 (ESD): air in the range of 15kV, contact in the range of 8kV and exceeds level 4: handles 20kV contact and 25kV air discharge, and with 61000-4-4 (EFT): 40A – 5/50ns; and with 61000-4-5 (surge). In addition, it is compatible with ISO 10605 (ESD): 330pF/2k ohm, in the range of 20kV contact. They can be used as replacements for MLV (0805) devices. The TVS array protects one power or I/O port and have an ESD protection greater than 25kV. The maximum peak current holds at 35A at 8/20 microseconds. The devices also offer a low clamping voltage and are RoHS and REACH compliant.

The TVS array is in a molded JEDEC SOD-323 package with an approximate weight of 5mg with lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin – Sn, 100) of 260-270 ºC. Operating and storage temperatures are -55 to 150 ºC and the flammability rating is UL 94V-0.

The TVS array devics are provided on 8mm tape and reel, per EIA Standard 481, in quantities starting at 3,000 units. Pricing information and purchasing details can be obtained by contacting any authorized worldwide distributor, representative, or directly with ProTek Devices.
