Slimline optocouplers protect home
appliances
Gate drive optocouplers in stretched small outline packages are designed for AC and DC brushless motors used in home appliances and industrial applications.
Avago Technologies has announced two new gate drive optocouplers in stretched small outline (SSO) packages for AC and DC brushless motors used in home appliances and industrial applications Avago's ACPL-W302 and ACPL-W314 gate drive optocouplers are an ideal solution for controlling variable-speed brushless motors in energy-efficient home appliances such as air conditioners and washing machines

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
Other applications include small- to medium-sized motors used for industrial equipment, switching power suppliers and inverters.
The package size for the ACPL-W302 and ACPL-W314 optocouplers is 50% smaller and substantially thinner than conventional dual-inline packages.
These optocouplers provide up to 8mm of creepage and clearance to meet stringent IEC, UL and CSA reinforced safety and insulation regulatory requirements.

IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
The creepage and clearance specifications of these SSO six-pin (SSO6) packages make them suitable for safety-critical applications.
Creepage is a spacing distance measured over a surface, such as the surface of an optocoupler.
Clearance is the shortest distance through air, such as between pins of an optocoupler.
"Industrial equipment and home appliances are being made more compact, which means they require smaller electronic assemblies that meet international standards for reinforced electrical isolation", said Kheng-Jam Lee, Worldwide Marketing Manager for Isolation Products in Avago Technologies' Optical Communication Solutions Division.
"To meet the growing demand for isolation products from our customers, Avago has expanded its series of optocouplers in SSO packages to include smaller optocoupler devices for motor drive and inverter applications".
Approvals to the following safety standards are pending: IEC/EN/DIN EN 60747-5-2 (Option 060 only), UL1577 and CSA Component Acceptance Notice 5, File CA 88324.
The ACPL-W302 is a 0.4A peak, and the ACPL-W314 a 0.6A peak isolated gate-drive optocoupler.
Both feature 15kV/us minimum common mode transient immunity at 1000V common-mode voltage (VCM) and operate in the -40 to +100C temperature range.
Performance characteristics include 0.7us maximum propagation delay and a wide 10 to 30V operating range, both over the full temperature range, and 3mA maximum supply current.
Samples and production quantities of the ACPL-W302 0.4A peak and ACPL-W314 0.6A peak isolated gate drive optocouplers in SSO6 packages are available now through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
