Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'G' against official Isocom documentation to confirm lead spread or compliance attributes. Ensure the ordering code matches the required package variant, as suffixes may indicate surface mount or tape-and-reel configurations. Cross-reference the manufacturer's latest datasheet to confirm RoHS status and availability before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when low input current and high isolation are required. The 70 V BVCEO supports moderate voltage switching. Compare against similar series like ISD204 or ISQ204 for package variations. Ensure the application environment stays within the specified operating temperature range and does not exceed the maximum ratings defined in the electrical characteristics table.

Transistor, Photovoltaic Output Optoisolators Part Context

The IS204 series belongs to Isocom Components' family of low-input-current phototransistor optocouplers. This series includes variants such as IS204-1, IS204-2, and IS204-3, which differ primarily in package type and lead configuration. The G suffix typically denotes a specific mechanical variation, such as lead spread, within the standard DIP form factor.
