4N35FVM

Transistor, Photovoltaic Output Optoisolators Overview

The onsemi 4N35FVM is a general-purpose phototransistor optocoupler featuring a single channel in a 6-SMD surface-mount package. It provides high isolation voltage of 7,500 Vpk and includes a base connection for the output phototransistor to enhance switching speed and linearity. The device utilizes an NPN phototransistor output capable of handling a maximum collector-emitter voltage of 30 V and a forward input current up to 50 mA DC.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix FVM confirms the 6-SMD package and base-connected configuration against the official datasheet. Ensure the procurement specification matches the required isolation voltage rating and thermal dissipation limits for the target application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface-mount technology is required alongside the functional benefits of a base-driven phototransistor. The base connection allows for faster turn-off times compared to standard variants without base access. Confirm that the 6-SMD footprint aligns with the printed circuit board layout constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the 4N35 series of general-purpose optocouplers manufactured by onsemi. While the standard 4N35 typically comes in a PDIP-6 through-hole package, the 4N35FVM variant adapts this functionality into a surface-mount form factor. It retains the core NPN phototransistor output architecture while offering enhanced switching characteristics via the integrated base terminal.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include other 6-SMD transistor output optocouplers with base connections from onsemi or compatible manufacturers. Verify pinout compatibility and isolation voltage ratings before substitution.
