Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SM' confirms the surface-mount package variant distinct from through-hole versions like 'V'. Confirm compliance with RoHS directives and check for UL, VDE, or IEC certifications required for the target application's safety standards. Ensure the operating temperature range meets system requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required at speeds up to 1 MBps. Compare against single-channel alternatives if only one channel is needed. Consider the surface-mount footprint constraints versus through-hole options available in the same family. Verify that the 5000 Vrms isolation rating satisfies the circuit's safety clearance requirements.
