Overview
The CNY75CXSM is a single-channel transistor output optocoupler manufactured by Isocom Components. It features a surface-mount plastic package with six pins and provides 5300 Vrms isolation voltage. The device utilizes an infrared LED input and a phototransistor output with a base terminal for enhanced performance. Key electrical parameters include a maximum forward voltage of 1.6 V, a maximum input current of 60 mA, and a typical rise time of 7 µs. The minimum current transfer ratio is specified at 320%, with a nominal value of 160%. Operating temperatures range from -55 °C to 100 °C, and the unit complies with UL and VDE standards.
Feature Summary
- Integrates a phototransistor with a dedicated base terminal to improve switching speed and linearity compared to standard configurations.
- Provides high-voltage electrical isolation rated at 5300 Vrms between input and output circuits.
- Designed for surface-mount assembly in a compact six-pin plastic package suitable for automated PCB placement.
Applications
- Signal isolation in microprocessor-based control systems
- Switch-mode power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'CXSM' against official Isocom documentation to confirm surface-mount configuration and pinout compatibility. Ensure that the required current transfer ratio meets the design specifications, as values can vary within the stated minimum and nominal ranges. Confirm compliance requirements such as UL or VDE recognition if applicable to the end equipment. Cross-reference the datasheet revision date to ensure parameter accuracy.
Selection Notes
Select this component when a phototransistor output with a base connection is required for improved response characteristics. The surface-mount format is suitable for space-constrained designs. Verify that the 5300 Vrms isolation rating aligns with safety regulations for the target application. Consider the operating temperature range of -55 °C to 100 °C for environmental suitability.
Part Context
The CNY75 series represents a family of transistor output optocouplers offered by Isocom Components. This specific model, CNY75CXSM, distinguishes itself through its surface-mount packaging and the inclusion of a base terminal on the output transistor. It shares functional similarities with through-hole variants but is optimized for modern PCB assembly techniques while maintaining high isolation capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer cross-reference guides for verified alternatives.
