BPC-817

Transistor, Photovoltaic Output Optoisolators Overview

The BPC-817 is a single-channel transistor output optocoupler manufactured by American Bright Optoelectronics Corporation. It integrates an infrared LED with a phototransistor in a DIP-4 through-hole package. Key electrical specifications include a maximum collector-emitter voltage of 35 V, a maximum collector current of 30 mA, and an isolation voltage of 5000 VRMS. The device features a forward current rating of 20 mA, a forward voltage of 1.2 V, and a maximum collector-emitter saturation voltage of 100 mV. Switching characteristics consist of a rise time of 4 µs and a fall time of 3 µs.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Designed for through-hole mounting to facilitate integration into standard printed circuit boards.

Transistor, Photovoltaic Output Optoisolators Applications

• Feedback control loops in flyback switch-mode power supplies
• Signal isolation in DC universal circuit systems
• Interface circuits connecting logic inputs to load outputs

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific bin classification (e.g., Bin B) against project requirements, as performance parameters may vary between bins. Confirm that the DIP-4 through-hole package aligns with the target PCB footprint. Ensure the selected component meets the required insulation voltage ratings for the intended safety isolation zone.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a low-cost, general-purpose optocoupler is needed for basic signal isolation. The 35 V collector-emitter voltage limit suits low-voltage logic interfacing. Verify that the 20 mA forward current capability matches the driving source constraints. Consider thermal dissipation limits if operating near maximum current ratings.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the BPC-817 series of transistor output optocouplers. It shares functional similarities with industry-standard PC817 devices but is produced by American Bright Optoelectronics Corporation. The series is commonly used in consumer electronics and industrial control systems requiring galvanic isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include PC817 variants (A/B/C/D), EL817, and AMS817. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that different manufacturers may offer varying bin classifications affecting current transfer ratio.
