Alpha and Omega Semiconductor has released a 7A 23V USB Type-C protection and reverse-blocking switch IC. Dubbed AOZ1377DI, is can be used in both Sink and Source applications and it “offers features that significantly reduce voltage drop and power loss compared to back-to-back p-channel devices”, promises the company. Instead it uses a pair of internal drain-to-drain n-channel mosfets, whose gates ...

Nexperia is aiming at protecting high-speed automotive data lines with ESD protection diodes whose capacitance is as low as 0.28pF. With stand-off voltages in the 18 – 32V range and a snap-back characteristic, the AEC-Q101 (automotive) qualified parts are intended to be used close to connectors on boards. The base part number is PESDxxVF1Byy-Q, with xx representing the nominal stand ...

Navitas recently announced its fourth generation of GaN power transistors with monolithically-integrated gate drivers. Branded GaNsafe, the company has increased the protection integrated alongside the driver and has moved to 10 x 10mm TOLL packaging, with a custom internal leadframe (diagram below). The initial products are rated at 650V (800V transients), cover Rds(on) from 35 to 98mΩ (table below), and ...

Bourns has introduced a series of gas discharge tubes for protecting equipment against high-voltage surges. The bidirectional GDT28H series has devices with breakdown voltages from 1 to 3.3kVdc, and all are 8mm in diameter and 6mm long, with out without axial leads. Picking the nominally 2kV GDT28H-200 as an example, breakdown is between 1,600 and 2,400V (100V/s). Arc voltage is ...

Cortec’s EcoEmitter is a stick-on capsule designed to protect un-ventilated enclosed electronic and optical equipment from corrosion. Each pod is intended to protect 0.25m3 (8.8feet3). “Vapour phase corrosion inhibitors emit and saturate the enclosure via diffusion, filling all void spaces and recessed areas with protective vapour molecules,” according to the company. “These molecules are attracted to and adsorb onto metallic ...

Kyocera AVX has announced small multilayer varistors (MLVs) that meet IEEE 100BASE-T1 and 1000BASE-T1 requirements. Available in 0402 and 0603 (0.5 ±0.1mm and 0.80 ±0.15mm respectively), they are rated for working voltages between 18 and 70Vdc, capacitance from 1.5 to 4.7pF, transients from 0.02 to 0.04J, peaks of 1 to 3A and operation across -55°C to +150°C. Actual working voltage ...

Nexperia is aiming at protecting USB 3.2, HDMI 2.0 and LVDS data lines in vehicles with family of ESD (electrostatic discharge) protection diodes. “Additionally, this portfolio also aims to address the upcoming high-speed video-links as well as the Open Alliance multi-Gbit Ethernet applications”, according to the company. All variants come in 1 x 0.6 x 0.5mm leadless packages to improve ...

Vishay Intertechnology has introduced a series of surface-mount bidirectional transient voltage suppressors in SMC (DO-214AB) packaging for automotive, industrial and telecom use. Surge capability is 3kW at 10/1,000μs to meet the specifications of ISO 16750-2 Pulse b. Called the SMC3KxxxCAHM3_A series, leakage current can be as low as 1μA from 22 to 120V, and operatioj is up to 175°C. For high reliability, ...

Amazing Microelectronic of Taiwan has introduced a low-capacitance ESD protection array for data and audio interfaces. “The multifaceted AZ1015-02N maintains low surge clamping voltage for ESD/EOS  protection and low capacitance to keep signal integrity,” according to New Yorker Electronics, which is stocking the part. “The device is used for audio interface, monitor and flat panel display, USB2.0 and SIM ports.” ...

Fuse holders for high voltage designs and with safety certifications have been added to TME’s portfolio. The distributor offers Conqueror’s wide current rating cylinder miniature fuses.  The cylindrical fuses are designed for through hole mounting. The miniature fuses are suitable for overcurrent protection on PCBs with limited available space. They are supplied with a plastic housing to reduce flammability and to withstand harsh, ...
