CNY17F3SR2VM_F132

Overview

The CNY17F3SR2VM_F132 is a single-channel phototransistor optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode with an NPN phototransistor output, providing electrical isolation via a 7500 Vrms insulation voltage rating. The device operates within a temperature range of -40°C to +100°C and features a maximum DC forward current of 60 mA. Key electrical parameters include a typical forward voltage of 1.5 V, a collector-emitter saturation voltage of 300 mV, and a minimum current transfer ratio of 100% at 10 mA input. It utilizes a surface-mount SMT-6 package.

Feature Summary

• Integrates a gallium arsenide infrared LED with an NPN phototransistor for signal transmission
• Provides high-voltage electrical isolation between input and output circuits
• Features low coupled capacitance to minimize noise interference

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic families
• Power supply feedback loops requiring galvanic separation

Procurement Notes

Verify the specific suffix F132 against the manufacturer's latest documentation to confirm packaging configuration and compliance status. Cross-reference the Mouser part number 512-CNY17F3SR2M_F132 for accurate sourcing details. Confirm availability status as listings may indicate regional sales restrictions or discontinuation notices. Ensure the component matches the required pinout and thermal specifications for the target PCB layout prior to final procurement authorization.

Selection Notes

Select this component when a robust 7500 Vrms isolation barrier is required for safety-critical applications. The NPN phototransistor output is suitable for sinking current in digital logic interfaces. Consider the 6-pin SMD form factor for space-constrained designs. Evaluate the 100% minimum current transfer ratio to ensure reliable switching performance under varying temperature conditions and aging factors.

Part Context

This part belongs to the CNY17 series of transistor-output optocouplers from onsemi. It shares functional similarities with other industry-standard devices like the 4N35 but offers enhanced isolation ratings and surface-mount packaging options. The series is widely recognized for general-purpose isolation tasks in consumer and industrial electronics.
