Product Description
The Vishay VOM1271T optocoupler is a specialized isolated MOSFET driver designed for surface mounting applications requiring efficient electrical isolation and signal transfer. Contained in a compact 4-pin SOP package, it integrates a MOSFET output stage that eliminates the need for an external power supply rails by deriving all drive current internally. This facilitates integration into compact circuits with simplified power management.
This single-channel optocoupler offers a maximum forward voltage of 1.6 V with a maximum input current of 50 mA. It achieves a robust isolation voltage of 4.5 kVrms, providing effective electrical separation between input and output, which is critical in industrial controls, solid-state relays, and floating power supplies. The device supports logic output, making it adaptable for interfacing with digital logic systems.
Operating temperature span from -40°C to 85°C enables its use in harsh industrial environments. Its switch timings, featuring a typical rise time of 53 µs and fall time of 24 µs, deliver responsive performance in control applications.
Maximum forward voltage of 1.6 V minimises power dissipation. Single channel device with MOSFET output for efficient switching. 4-pin SOP surface mount package optimized for PCB integration. Isolation voltage rated at 4.5 kVrms for superior electrical isolation.
Operating temperature range supports diverse environmental conditions from -40°C to 85°C. Compliant with UL 1577 and CSA standards to assure safety and reliability. Typical rise and fall times support quick signal transfer with 53 µs and 24 µs respectively.
Logic output compatibility facilitates connection to microcontrollers and digital systems.
This Optocoupler is ideal for use in industrial machines, power electronics, automation equipment, HVAC systems, and other applications requiring high-voltage isolation, secure switching, and compact assembly.
