ILD205/206/207/211/213/217 FEATURES • Two Channel Coupler • Industry Standard SOIC-8 Surface Mountable Package • Standard Lead Spacing of .05" • Available in Tape and Reel Option (Conforms to EIA Standard 481-2) • Isolation Test Voltage, 2500 VRMS • High Current Transfer Ratios ILD205, 40 – 80% ILD206, 63 –125% ILD207, 100 – 200% ILD211, 20% Minimum ILD213, 100% Minimum ILD217, 100% Minimum at 1 mA • High BVCEO, 70 V • Compatible with Dual Wave, Vapor Phase and IR Reflow Soldering DESCRIPTION The ILD205/206/207/211/213/217 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 ILD205/6/7/11/13/17 come in a standard SOIC-8 small outline package for surface mounting which makes it 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.
