Avago's solid-state relays

Avago Technologies has unveiled three families of solid-state relays (SSRs) that promise the industry's highest insulation voltage in a miniature SO-4 package. Achieving an industry high of 3.75kV in insulation protection, Avago said its expanded family of SSRs with MOSFET outputs enable designers to improve power efficiency, performance and reliability in low- and high-current circuitries often found in telecommunications, consumer electronics, automotive and industrial markets.

According to the company, ASSR-1510/1511/1520 (60V, 1A, 0.5 ohm) devices offer the fastest switching speed available in the 1A SSR market. Along with the ASSR-15xx, the ASSR-4110/4120 (400V, 0.12A, 25 ohm) and ASSR-1410/1420 (60V, 0.6A, 1 ohm) products are available as a 1 Form A (single-channel) SSR with MOSFET output in a SO-4 package and as a 2 Form A (dual-channel) SSR in a DIP-8 package. Each product family features qualified performance across a wide temperature range of -40C to 85C, fast switching speed of less than 1ms, and high transient immunity greater than 1kV/?s. The small SO-4 package size gives designers much needed board space without compromising insulation performance, the company said.

Designers are in search of ways to efficiently and quickly switch signals and power in their products for factories or for homes without sacrificing performance or safety. Size limitations and reliability are also critical issues that are driving the trend of replacing electromechanical relay with solid-state relays.

Relays are found in a wide variety of applications, ranging from long-life applications such as digital I/O cards for industrial control and analog circuits in automated test equipment, to consumer applications such as modems for telecommunications and detectors or surveillance circuits for security equipment.

Pricing for the ASSR-1410/1420 begins at $1.48 (SO-4) and $2.49 (DIP-8); $1.20 (SO-4) and $2.31 (DIP-8) for the ASSR-4110/4120; and $2.41 (SO-4), $2.22 (DIP-6) and $4.44 (DIP-8) for the ASSR-1510/1511/1520. All pricing are for 10,000-unit orders.
