Isolation voltage and switching performance
Rated for 7500Vpk isolation, this optoisolator provides reinforced galvanic isolation for signal paths in industrial power supplies, motor drives, and PLC digital inputs where transient voltage spikes are a concern. Typical turn-on and turn-off times are 2µs each, supporting signal isolation up to low-speed logic or status feedback at a few hundred kHz.
Current transfer ratio and drive margin
Minimum CTR is 20% at 10 mA forward current, meaning the output transistor can sink at least 2 mA when the LED is driven at 10 mA. This ensures enough base drive to saturate the output for standard TTL or CMOS logic loads. Vce saturation is 400mV max, keeping the output voltage drop low when the transistor is fully on — important for maintaining logic-high thresholds at the receiver.
Package and temperature range
Housed in a 6-SMD Gull Wing package (6-SMD), suitable for reflow soldering on standard surface-mount boards. The 6-pin footprint matches the industry-standard DIP-6 layout with formed leads for surface mounting. Operating temperature spans -40°C to 100°C, covering industrial and outdoor equipment enclosures without active cooling.
