• Reliable low cost construction utilizing molded plastic technique
• Plastic material has UL flammability classification 94V-O
• Typical IR less than 1uA above 10V
• Fast response time: typically less than 1.0ps from 0 Volts to VBR min
• Glass passivated junction
• Low inductance
• I/O interface • AC/DC power supply
• Low frequency signal transmission line (RS232, RS485, etc.)
