Digital optocouplers operate over the -40 to +125°C range

November 27, 2012 // By Julien Happich
Avago Technologies announced its ACPL-M49U/K49U/M71U/M72U digital optocouplers designed to meet customer needs for low power, low leakage, higher isolation voltage and higher common-mode rejection (CMR) in over the extended temperature range of -40 to +125°C.

The ACPL-M71U/M72U devices are high speed, low power digital optocouplers with R2Coupler isolation and a low power consumption of 1.5mA. The ACPL-M71U uses a high-speed LED to achieve 35ns maximum propagation delay, while the ACPL-M72U uses a low current LED for lower power consumption. The ACPL-M49U/K49U are low speed, high CMR digital optocouplers, both configurable as low power and low leakage optocouplers. An internal shield also ensures a CMR of typical 30 kV/µs at 1500V common-mode voltage. The ACPL-M49U, ACPL-M71U and ACPL-M72U are single-channel optocouplers in 5-lead small-outline (SO5) packages. The ACPL-K49U is a single-channel optocoupler in an 8-lead small-outline (SO8) package.

All new optocouplers are compliant to industrial safety standards such as IEC/EN/DIN EN 60747-5-5 approval for reinforced insulation, UL 1577 and CSA.

R2Coupler isolation provides the reinforced insulation and reliability that delivers safe signal isolation that is critical in high temperature industrial applications.
