Compared to electromechanical relays, Avago's ASSR-3220 and ASSR-322R products offer distinct advantages, including the elimination of contact bounce, and problems due to shock, vibration, or mounting position. They have no wearout mechanism limiting the number of operations, and require no minimum contact "wetting" current. They are also free from magnetic fields, do not generate electrical noise, and are not sensitive to electromagnetic interference.
Both ASSRs, with reinforced insulation, feature fast turn-on and turn-off, excellent noise rejection for transient immunity, and low input drive current making them CMOS- (complementary metal oxide silicon) compatible and perfect for battery-operated and USB (universal serial bus)-powered applications.
Avago's new SSRs are dual channel, providing two independent Form A (normally open) single-pole single-throw (SPST) relays in an industry-standard 8-pin dual-inline package (DIP). Their output ratings are 250V maximum load voltage and 200mA continuous output current. Their qualified performance across operating temperature range and transient immunity is unique to SSRs currently available on the market. Their excellent noise rejection between input-output as well as between open terminals on the output will eliminate undesirable transient effects. Reinforced insulation of 3.75kV with fast switching speed makes them suitable for a wide range of industrial, consumer and telecommunications switching applications.
The ASSR-322R features 1nA maximum off-state leakage, low on-resistance of 8.5 OMEGA maximum, low output capacitance of 60 pF maximum at 1 MHz and outstanding maximum turn-on and turn-off times of 0.5ms and 0.2ms, respectively.
"As a leading supplier of high-performance optocouplers, Avago continues to excite the market by introducing these new SSRs with enhanced features," said Chong Tze Siong, vice president and general manager of Avago Technologies' Optical Communications Solutions Division. "Reinforced insulation, transient immunity and high-speed performance of our optocouplers have always been the industry benchmarks, and we will maintain our technology leadership by introducing new products with value-added benefits."
U.S. Pricing and Availability
The Avago ASSR-3220 is priced at $3.40 each and the ASSR-322R at $4.20 each, both in 1,000-piece quantities. Both versions are supplied in conventional 8-pin DIPs for through-hold mounting, and are available with a gull wing surface-mount configuration. They are available now through Avago Technologies' direct sales channel and worldwide distribution partners. The single channel versions in 6-pin DIP and 4-pin SOP will be available in the fourth quarter.
