VOM452T

Transistor, Photovoltaic Output Optoisolators Overview

The VOM452T is a high-speed analog optocoupler manufactured by Vishay Semiconductor Opto Division. It features a GaAlAs infrared emitting diode optically coupled to a transistor output, housed in a low-profile SOP-5 package with a thickness of 2.0mm. The device supports a baud rate of 1 MBd and provides an isolation voltage of 3750Vrms. Key electrical parameters include a maximum output voltage of 25V, an output current of 8mA per channel, and a typical forward voltage of 1.4V. The DC forward current maximum is 25mA, with a current transfer ratio ranging from 20% to 50% at 16mA input. Operating temperatures span from -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix (e.g., T for tape and reel) against the manufacturer's datasheet to ensure correct packaging configuration. Confirm that the SOP-5 footprint matches the target PCB design, as dimensions differ from standard DIP packages. Check for recent Product Change Notifications regarding manufacturing site transfers or material updates to ensure supply chain consistency and compliance with project specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed analog signal isolation is required in space-constrained designs. The SOP-5 package offers significant board area savings compared to traditional DIP-8 options. Ensure the application operates within the specified -55°C to 100°C temperature range and respects the 25V output voltage limit. Verify that the 1 MBd speed requirement aligns with the system's data rate needs.

Transistor, Photovoltaic Output Optoisolators Part Context

The VOM452T belongs to Vishay's VOM45x series of high-speed optocouplers, designed specifically for applications demanding fast switching speeds in compact form factors. It shares architectural similarities with the VOM453T but differs in specific internal configurations. This series represents a shift toward smaller surface-mount solutions for industrial and communication equipment, replacing larger through-hole alternatives while maintaining high isolation standards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The VOM453T is a documented substitute within the same product family. Both devices share identical packaging and general specifications. Verify functional equivalence for the specific circuit requirements before substitution, as internal differences may exist between the VOM452T and VOM453T variants.
