HCPL2531TSR2VM

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL2531TSR2VM is a dual-channel high-speed optocoupler manufactured by Fairchild Semiconductor (now onsemi). It features an AlGaAs LED optically coupled to phototransistor outputs, providing electrical isolation between input and output circuits. The device supports a data rate of 1 Mb/s and offers a maximum isolation voltage of 5000 Vrms. It operates within a temperature range of -40°C to +100°C and is housed in an 8-pin surface-mount package.

Transistor, Photovoltaic Output Optoisolators Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical insulation isolation between system components
• Impedance transformation in circuit interfaces

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or onsemi, as corporate acquisitions may affect labeling. Confirm the specific suffix 'TSR2VM' corresponds to the required tape-and-reel packaging format and lead-free composition. Ensure the component meets RoHS 6 compliance requirements if specified for your project. Cross-reference the datasheet revision date to confirm technical specifications have not changed since publication.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required at high speeds. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the surface-mount package constraints against PCB layout requirements. Compare the 1 Mb/s data rate against system timing needs. Verify the -40°C to +100°C operating range matches environmental conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-2531 series of high-speed optocouplers. It shares architectural similarities with single-channel variants like the HCPL-2530 but provides two isolated channels in one package. The series is designed for applications requiring fast response times and reliable galvanic isolation in compact form factors.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-2531 variants from onsemi with compatible pinouts and specifications. Check for equivalent packages such as SMD8 or DIP-8 depending on mounting requirements. Verify that alternative parts maintain the same 5000 Vrms isolation and 1 Mb/s speed ratings.
