Fairchild debuts mini-flat package configuration for optocouplers

South Portland, Maine–Fairchild Semiconductor International has introduced a new mini-flat package configuration for optocouplers, according to Steve Sherman, Fairchild’s senior vice president for the Optoelectronics Group.

The mini-flat package configuration is 70% smaller than dual inline package configurations, and it will be used for packaging optocouplers that are used in applications where small component size is crucial. The first products to be offered in the mini-flat package are the HMA121, HMA124, HMA2701 and HMAA2705 optocouplers.

The HMA series optocouplers consist of a single gallium arsenide infrared emitting diode (dc input) driving a silicon phototransistor. The HMA121 has a current transfer ratio (CTR) of 50 to 600%, the HMA124 has a CTR of 100 to 1200%, and the HMA2701 has a CTR of 50-300%. The optocouplers are ideal for use in applications such as microprocessor input, digital logic input, power supply monitor, twisted pair line receiver, and telephone line receiver, according to the company.

The HMAA optocoupler consists of two gallium arsenide infrared emitting diodes connected in inverse parallel (ac input) driving a silicon phototransistor. The HMAA2705 has a CTR of 50 to 300%, and is ideal for use in applications such as ac line monitor, unknown polarity dc sensor, and telephone line receiver.

All of the optocouplers are BSI, CSA, and UL certified, available in tape and reel configuration, and direct replacements for NEC, Sharp, and Toshiba. U.S. list prices for 10,000 piece quantities are $0.17 for the HMA121, $0.17 for the HMA124, $0.17 for the HMA2701 and $0.29 for the HMAA2705.
