4N35SVM

Transistor, Photovoltaic Output Optoisolators Overview

The onsemi 4N35SVM is a single-channel optocoupler featuring an NPN phototransistor output with a base terminal for enhanced switching control. It utilizes a surface-mount 6-SMD (鸥翼) package and provides high isolation capability of 4170Vrms between input and output circuits. The device supports a maximum DC forward current of 60 mA and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a minimum current transfer ratio of 100% at 10 mA, a maximum collector-emitter voltage of 30 V, and a typical turn-on/turn-off time of 2 µs.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific order matches the 4N35SVM surface-mount variant rather than through-hole equivalents like the 4N35M. Confirm the presence of the base pin configuration if fast switching performance is required. Ensure the packaging type aligns with automated assembly needs, as this model is typically supplied in tape and reel formats for SMD processing.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the 4N35SVM when surface-mount technology is mandatory and faster response times are needed due to its base-driven output structure. Compare against the 4N35VM for through-hole requirements or the 4N35SR2M if different reel specifications are preferred. Evaluate the 4170Vrms isolation rating against system safety standards and ensure the 60 mA forward current limit meets drive circuit capabilities.
