Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TVM' corresponds to the tape and reel packaging configuration rather than bulk or tube formats when sourcing. Confirm RoHS compliance status through the official datasheet as manufacturing processes may vary by region. Ensure the ordering part number matches the exact pinout and isolation ratings required for your circuit design before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a phototransistor output with a base connection is necessary for faster switching applications compared to standard variants without a base. Consider the 70 V collector-emitter voltage limit for low-voltage logic interfacing. Evaluate the 90 mA forward current requirement against available drive sources to ensure adequate LED illumination without exceeding maximum ratings.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the CNY172 series of high breakdown voltage phototransistor optocouplers. The 'TVM' designation typically indicates specific packaging and handling characteristics defined by onsemi. It serves as a general-purpose isolation component suitable for replacing older equivalents in legacy designs while offering modern reliability standards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other CNY172 variants such as CNY172-1, CNY172-2, or CNY172-3, which share identical pinouts but differ in Current Transfer Ratio (CTR) bins. Verify that any replacement maintains the same 6-DIP package dimensions and isolation voltage ratings.
