CNY75BXG

Overview

The CNY75BXG is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a transistor output with an accessible base terminal, housed in a 6-DIP package. The device provides an isolation voltage of 5300Vrms. Key electrical parameters include a maximum forward voltage of 1.65V and a maximum input current of 60 mA. Typical switching characteristics consist of a rise time of 2µs and a fall time of 11µs.

Feature Summary

• Integrates a phototransistor with a dedicated base connection for external control or speed enhancement.
• Provides high-voltage electrical isolation between input and output circuits.
• Utilizes a standard 6-pin dual in-line package for through-hole mounting.

Applications

• Industrial control systems requiring signal isolation
• Power supply circuit feedback loops
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix 'BXG' against official Isocom documentation to confirm pinout and mechanical dimensions. Ensure the procurement source provides valid traceability for this component variant. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit units. Confirm that the 6-DIP package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a base terminal on the output transistor is required for improved switching performance or linear operation. Compare the 5300Vrms isolation rating against system safety standards. Evaluate the 2µs typical rise time against the required signal bandwidth. Ensure the 60 mA maximum input current aligns with the driving circuit capabilities.

Part Context

This component belongs to the CNY75 series of transistor output optocouplers. Unlike standard variants without base access, this model exposes the phototransistor base. This design allows for external biasing or faster discharge of junction capacitance. It serves as a specialized alternative within the broader family of general-purpose optoisolators.

Replacement Considerations

Direct substitutes may include other CNY75 variants with base connections from Isocom or equivalent models from manufacturers like Vishay or Sharp. Verify that replacement parts maintain the 6-DIP package and 5300Vrms isolation rating. Check if the alternative offers compatible current transfer ratios and switching speeds.
