HCPL0500V

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL0500V is a single-channel high-speed transistor output optocoupler manufactured by Fairchild Semiconductor. It integrates an AlGaAs LED optically coupled to a photodetector transistor housed in an 8-pin SOIC package. The device features a separate base connection for the photodiode, which significantly reduces base-collector capacitance to achieve speeds several orders of magnitude faster than conventional phototransistor optocouplers. Key electrical parameters include a maximum forward current of 25 mA, a maximum collector-emitter voltage of 30 V, and a minimum common mode transient immunity of 15 kV/µs at 1500 V. It supports data rates up to 1 Mbit/s and operates within a temperature range of -40°C to 85°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

Transistor, Photovoltaic Output Optoisolators Applications

• Line receivers in digital communication systems
• Pulse transformer replacement in isolated circuits
• Output interface coupling to CMOS, LSTTL, and TTL logic families
• Wide bandwidth analog signal coupling applications

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'V' indicates UL recognition file E90700 and potential VDE approval status as documented in official Fairchild datasheets. Confirm RoHS compliance status (e3) and packaging type (Tube) against the latest manufacturer specifications. Ensure the component matches the 8-SOIC footprint and verify the operating temperature range requirements align with the specified -40°C to 85°C limits before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed isolation is required without the complexity of integrated logic gates. The open collector output necessitates external pull-up resistors, so ensure circuit design accounts for this. Compare against HCPL04XX series if base bonding is not required for noise margin, or HCPL053X series if dual-channel density is needed. Verify insulation voltage ratings meet system safety standards.

Transistor, Photovoltaic Output Optoisolators Part Context

The HCPL0500V belongs to the HCPL05XX family of high-speed transistor optocouplers from Fairchild Semiconductor. This family shares the core technology of using an AlGaAs LED and a photodetector transistor with a separate base connection. Variants like HCPL0500 and HCPL0501 differ primarily in certification options and packaging details, while the HCPL053X series offers dual channels. The 'V' suffix typically denotes specific regulatory approvals.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include HCPL0500 or HCPL0501 depending on required certifications. For dual-channel needs, consider HCPL0530 or HCPL0531. Ensure any substitute maintains the 1 Mbit/s speed rating and 8-SOIC package compatibility. Verify that the alternative part supports the same open collector output configuration and isolation voltage requirements.
