HCPL-6531

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-6531 is a high-reliability, Class H, two-channel hermetically sealed optocoupler manufactured by Broadcom Limited. It utilizes a GaAsP light-emitting diode coupled to a phototransistor with base output. The device is housed in a 20-pad leadless ceramic chip carrier (LCCC) package with solder-dipped pads. Key electrical specifications include an isolation voltage of 1500 VDC and a data rate of 400 kb/s. The typical turn-on time is 400ns, while the typical turn-off time is 1µs. It operates within a temperature range of -55°C to 125°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code on the component marking to ensure it matches the requested LCCC-20 package variant. Confirm that the hermetic seal integrity meets Class H requirements for your specific environmental conditions. Check datasheet limits for forward current and collector-emitter voltage before integration.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when hermetic sealing and high thermal stability are critical. The 20-pin LCCC package requires specific surface-mount or board-level mounting techniques distinct from standard plastic packages. Ensure the circuit design accommodates the 1µs turn-off time for signal timing constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to Broadcom's HCPL series of optocouplers, specifically designed for high-reliability applications. The HCPL-6531 variant distinguishes itself through its hermetically sealed ceramic package and Class H rating, offering superior durability compared to non-sealed plastic counterparts in harsh environments.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the 20-LCCC package and hermetic sealing. Verify pinout compatibility with existing PCB layouts. Consider equivalent Class H optocouplers from other manufacturers if sourcing constraints exist, ensuring identical isolation voltage and channel count.
