The ACPL-M50L provides superior high voltage performance over the lifetime of the product while meeting safe insulation requirements for reinforced applications. Available in a small outline-5 (SO-5) package size, Avago’s ACPL-M50L high speed digital optocoupler supports a wide supply voltage range from 2.7 to 24-volts and is driven by low forward drive current (IF > 3mA) with a high current transfer ratio (CTR > 80 percent min.) to allow direct drive from a microcontroller without the need to add a buffer chip.
Separate connections for the photodiode bias and output transistor collector of the ACPL-M50L increases its speed up to a hundred times over that of a conventional photo-transistor by reducing the base-collector capacitance. Additionally, this optocoupler operates over a wide temperature range from -40 to +105 degrees-C making it ideal for use in harsh industrial environments.
