Geneva, Switzerland STMicroelectronics has introduced the USBULC6-2M6, an electrostatic discharge (ESD) protection device that meets the complete protection requirements for high-speed USB including Vbus in an ultra-miniature QFN-6 package, measuring 1.0 x 1.45 x 0.65 mm. With 0.85 pF maximum capacitance at 240 MHz, the USBULC6-2M6 minimizes distortion and helps designers meet the 10 pF maximum specified line loading for operation up to 480 Mbits/s.
The small package makes the USBULC6-2M6 well-suited for mobile phones, handheld computers, personal media players and other portable high-speed communicators requiring IEC61000-4-2 protection. The device meets level 4 specifications to 15-kV air-gap discharge and 8-kV contact discharge, and offers a breakdown voltage of 6.1 V. In addition, the low maximum leakage current of 0.5 microamps reduces power consumption and preserves battery life.
By providing two complementary protection-diode networks, with capacitance matching within 0.1 pF, the USBULC6-2M6 is suitable for a wide range of high-speed differential and single-ended signaling applications. Zero insertion loss is specified up to 3 GHz, allowing use in applications such as Gigabit Ethernet as well as future high-speed protocols. Other benefits include very low clamping voltage compared to metal oxide varistors, which is are alternative devices for the application, to provide enhanced protection for sub-100-nm CMOS ICs.
Pricing: The USBULC6-2M6 is available now at $0.20 for orders over 1000 units.
