OLF449中文资料Phototransistor Optocouplers数据手册Skyworks规格书

描述 Description

The OLF449 consists of an LED that is optically coupled to anN-P-N silicon phototransistor, mounted in an eight-pin hermetic surface mount flat package. The leads can be formed to provide compliant solder connections to the mounting substrate.

Electrical parameters are similar to the JEDEC registered 4N49optocoupler, but with much better CTR degradation characteristics due to radiation exposure. Special electricalparametric selections are available on request.
