CNY172SVM

Transistor, Photovoltaic Output Optoisolators Overview

The CNY172SVM is a single-channel optocoupler featuring an infrared emitting diode and a phototransistor with a base lead. It provides electrical isolation of 4170 Vrms between input and output circuits. The device utilizes a 6-SMD surface-mount package, designed for compact PCB layouts. Key electrical characteristics include a collector-emitter voltage (Vceo) of 70 V and a high breakdown voltage capability for the phototransistor. The component supports industrial automation and motor drive applications requiring reliable signal transmission across isolated boundaries.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SVM' to confirm the 6-SMD package variant and base-lead configuration. Ensure compliance with RoHS standards as indicated by manufacturer documentation. Cross-reference the 4170 Vrms insulation rating against application safety requirements. Confirm the 70 V collector-emitter voltage meets circuit load specifications. Validate the single-channel architecture matches system isolation needs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a phototransistor output with base access is required for precise timing or gain control. The 6-SMD form factor suits high-density surface-mount designs. Verify that the 70 V output voltage rating accommodates the downstream logic or analog levels. Consider the 4170 Vrms isolation barrier for safety-critical interfaces. Evaluate the CTR range if signal integrity at low currents is critical.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the standard optocoupler family from onsemi, specifically designed for general-purpose isolation tasks. The CNY172 series is widely recognized in industrial electronics for its reliability. The SVM suffix denotes the specific surface-mount packaging and pinout configuration, distinguishing it from through-hole DIP variants within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct pin-compatible alternatives with matching 4170 Vrms isolation and 70 V Vceo ratings. Verify that substitute components maintain the base-lead feature for equivalent switching performance. Ensure the replacement offers similar current transfer ratio characteristics for signal fidelity.
