SMALL OUTLINE SURFACE MOUNT PHOTOTRANSISTOR OPTOCOUPLER
FEATURES · High Current Transfer Ratio, IF=10 mA, VCE=5 V IL205A, 4080% IL206A, 63125% IL207A, 100200% IL208A, 160320% · High BVCEO, 70 V · Isolation Test Voltage, 2500 VACRMS · Industry Standard SOIC-8 Surface Mountable Package · Standard Lead Spacing, .05" · Available in Tape and Reel Option--Suffix "T" (Conforms to EIA Standard RS481A) · Compatible with Dual Wave, Fapor Phase and IR Reflow Soldering · Underwriters Lab File #E52744 (Code Letter P) DESCRIPTION The IL205A/206A/207A/208A are optically coupled pairs with a Gallium Arsenide infrared LED and a silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. The IL205/ 6/7/8 come in a standard SOIC-8 small outline package for surface mounting which makes them ideally suited for high density applications with limited space. In addition to eliminating through-holes requirements, this package conforms to standards for surface mounted devices. A specified minimum and maximum CTR allows a narrow tolerance in the electrical design of the adjacent circuits. The high BVCEO of 70 volts gives a higher safety margin compared to the industry standard 30 volts.
