HCPL-817-W00E

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-817-W00E is a single-channel transistor output optocoupler manufactured by Broadcom Limited. It features an NPN phototransistor output and utilizes a PDIP-4 Gull Wing package for through-hole mounting. The device provides a high insulation voltage of 5000 Vrms, ensuring robust galvanic isolation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum collector current of 50 mA, and a forward current of 50 mA with a typical forward voltage of 1.4 V. The unit exhibits rise and fall times of 18 µs each, with a power dissipation rating of 200 mW. It operates within a temperature range of -30°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix W00E against the manufacturer's latest datasheet to confirm pinout configuration and packaging details. Ensure compatibility with existing PCB footprints, as package variations exist within the HCPL-817 series. Cross-reference RoHS compliance status directly with official documentation prior to procurement to meet regulatory requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel of isolation with moderate speed (18 µs) is required. The 35 V collector-emitter voltage limit defines its suitability for low-voltage logic interfacing rather than high-voltage power stages. Consider the through-hole package constraint if surface mount alternatives are not feasible for the assembly process.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-817 family of transistor output optocouplers from Broadcom Limited. The family offers various configurations distinguished by suffix codes that indicate packaging type and current transfer ratio specifications. The HCPL-817 series is widely recognized for providing reliable isolation in cost-sensitive electronic designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify functional equivalence with other HCPL-817 variants only if their datasheets explicitly state identical pinouts and electrical characteristics.
