Neubiberg, Germany — Infineon claims the industry's smallest TVS protection diode that measures 0.6 x 0.3 mm2 and 0.3-mm high. The electrostatic discharge (ESD) series diode is designed to protect the latest high-speed data communications and consumer devices.

The TVS diode can reliably absorb electrostatic discharges as high as 20 kV and offers a response time of less than 0.5 ns. Uni-directional and bi-directional versions are available to support a range of different applications.

The ESD8V0R1B-02LS is a bi-directional TVS diode designed for use in a wide voltage range from -8 to +14 V. With a parasitic capacitance of 4 pF, it ensures signal integrity on high-speed interfaces such as USB 2.0 and Firewire in electronic equipment including mobile phones, MP3 players, and digital video and digital still cameras. At less than 1 nA, its leakage current, an important factor in battery-powered devices, is the lowest in the industry, said Infineon. The diode's low breakdown voltage of 17 V protects electronics against transients and electrostatic discharges.

The uni-directional ESD5V3U1U-02LS TVS diode targets equipment interfaces operating at higher data rates, such as HDMI (1.65 Gbits/s) or S-ATA (3 Gbits/s). The parasitic capacitance has been reduced by a factor of 10 to an industry-leading 0.4 pF. The diode is designed for applications with an operating voltage of 3.3 V or 5.3 V. The device offers a contact discharge of more than 20 kV (to IEC61000-4-2) and a clamping voltage of 12 V or 4 V in the negative direction.

The devices are housed in a TSSLP-2-1 package, which complies with the RoHS directive.
