TVS arrays protect smartphones

ProTek Devices has launched its new GBLCxxHP/CHP series of ultra-low-capacitance TVS arrays  that provide circuit protection for smartphones, other handheld wireless systems, USB interfaces, and Ethernet 10/100/1000 Base T applications. The TVS arrays offer an ultra-low capacitance of 3 pF (typical) and also provide a low leakage current of less than 0.5 µA.

The four new devices include the GBLC03HP and GBLC03CHP devices, with rated stand-off voltages of 3.3 V, and the GBLC05HP and GBLC05CHP with rated stand-off voltages of 5 V. They are available in both unidirectional and bidirectional configurations and are rated at 750 W for an 8/20-µs waveshape.

These transient voltage suppressors can be used as replacements for MLV (0805) devices, said ProTek. They protect one power or I/O port and provide an electrostatic discharge (ESD) protection greater than 25 kV. The maximum peak current holds at 35 A at 8/20 µs. The devices also offer a low clamping voltage.

The GBLCxxHP/CHP series is compatible with IEC standards 61000-4-2 (ESD) and exceeds Level 4 (20-kV contact and 25-kV air discharge). The devices are also compatible with IEC 61000-4-4 (EFT), IEC 61000-4-5 (surge), and ISO 10605 (ESD). The devices also are RoHS- and REACH-compliant.

The devices are housed in a molded JEDEC SOD-323 package with an approximate weight of 5 mg and are provided on 8-mm tape and reel, per EIA Standard 481, in quantities starting at 3,000 units. They offer lead-free pure-tin plating (annealed) and a solder reflow temperature (pure tin — Sn, 100) of 260°C to 270°C. The operating and storage temperatures are –55°C to 150°C. Flammability rating is UL 94V-0.
