Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix K indicates MIL-PRF-38534 compliance when sourcing. Confirm RoHS non-compliance status due to lead content if environmental regulations apply. Ensure the 20-LCCC package dimensions match the PCB footprint requirements. Validate supplier authorization from Broadcom Limited to guarantee authenticity and traceability for military-grade components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when hermetic sealing and military qualification are mandatory. The dual-channel configuration reduces board space compared to single units. Consider the 400 kb/s data rate limit for signal integrity. The wide temperature range supports extreme operational conditions. Verify interface compatibility with existing transistor-based logic circuits.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL-6 series of high-speed optocouplers. It represents a specialized variant designed for defense and aerospace applications where standard commercial parts are insufficient. The LCCC package offers superior thermal and mechanical stability compared to plastic packages. It serves as a bridge between low-voltage control logic and high-voltage isolated domains.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes must match the 20-LCCC package and MIL-PRF-38534 K-class certification. Generic industrial optocouplers lack the required hermetic seal and radiation hardness. Verify pinout compatibility before swapping with other HCPL-6 variants. Non-military grade equivalents may not withstand the specified temperature extremes.
