Overview
The PVI5033RS-T is a photovoltaic output optocoupler manufactured by Infineon Technologies, featuring two independent channels in an SMT8 surface-mount package. It utilizes Microelectronic Relay (MER) technology to provide high isolation voltage of 3750 Vrms and an output voltage of 5 V. The device operates within a temperature range of -40°C to +85°C and supports a forward current of 10 mA. This component serves as a solid-state relay replacement for applications requiring reliable electrical isolation.
Feature Summary
- Generates output voltage directly from incident light without requiring external bias power
- Provides galvanic isolation between input and output circuits using MER technology
- Features dual-channel configuration for simultaneous signal transmission
Applications
- Solid-state relay replacements in industrial control systems
- Isolation interfaces for analog signal processing circuits
- Safety-critical monitoring systems requiring high dielectric strength
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Check for end-of-life notifications such as NRND status before finalizing procurement plans. Ensure storage conditions account for moisture sensitivity levels specified in the handling guidelines.
Selection Notes
Select this component when high isolation voltage and low leakage current are critical requirements. Consider the SMT8 package dimensions for PCB layout constraints. Evaluate the 10 mA forward current capability against drive circuit limitations. Compare performance characteristics with alternative photovoltaic isolators if higher channel counts or different packaging options are needed.
Part Context
This part belongs to Infineon's photovoltaic isolator family, designed to replace mechanical relays. It shares architectural similarities with other PVI5033 variants but differs in packaging and reel specifications. The technology leverages microelectronic relay principles to achieve long operational life and fast switching speeds compared to traditional electromechanical solutions.
Replacement Considerations
Direct substitutes include PVI5033RSPBF for tube packaging equivalents. Verify pinout compatibility and thermal characteristics when cross-referencing with competitor photovoltaic isolators. Ensure that any replacement maintains the required 3750 Vrms isolation rating and 5 V output capability.
