HCPL2531TVM

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL2531TVM is a dual-channel high-speed optocoupler manufactured by onsemi. It features an AlGaAs LED optically coupled to a phototransistor output, providing electrical isolation with a maximum insulation voltage of 5000 Vrms. The device supports a nominal data rate of 1 MBps and operates within a temperature range of -40°C to 70°C. Packaged in an 8-pin PDIP (DIP) configuration, it is designed for applications requiring fast signal transmission across isolated boundaries.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel architecture for independent signal isolation
• High-speed transistor output for rapid signal transmission
• Robust electrical isolation capability up to 5000 Vrms

Transistor, Photovoltaic Output Optoisolators Applications

• Digital isolation in industrial communication systems
• Signal coupling between microcontrollers and power circuits
• Replacement for pulse transformers in broadband analog coupling

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TVM' against current manufacturer documentation, as this variant may be subject to obsolescence or discontinuation notices. Confirm that the PDIP package and lead-free status align with your assembly requirements. Cross-reference the datasheet revision date to ensure compliance with current safety standards such as UL and VDE approvals before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with 1 MBps speed is required in a through-hole DIP package. Ensure the input forward current and output collector current ratings match your circuit design constraints. Consider the operating temperature range and insulation voltage requirements to verify suitability for the intended application environment compared to surface-mount alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-2531 series of dual-channel high-speed optocouplers from onsemi. It shares architectural similarities with single-channel variants like the 6N135 but provides two isolated channels in one package. The series is designed to replace pulse transformers and offers TTL and CMOS compatibility for digital logic interfacing.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The manufacturer indicates that the HCPL253xM series serves as the new equivalent part number. Verify if the M-suffix variants offer identical pinouts and electrical characteristics to ensure a direct drop-in replacement without redesigning the PCB layout.
