HCPL-530K

Logic Output Optoisolators Overview

The HCPL-530K is a Class K hermetically sealed logic output optocoupler from Broadcom Limited. It features a GaAsP LED optically coupled to an integrated high-gain photo detector in an 8-pin ceramic DIP package with trimmed leads. Key electrical parameters include a maximum propagation delay of 750 ns, a typical pulse width distortion (PWD) of 450 ns, and a current transfer ratio (CTR) of 90%. The device supports a maximum continuous output current of 15 mA with a forward current of 20 mA. Operating temperatures range from -55°C to +125°C, and it offers a common mode transient immunity (CMTI) of 10 kV/µs.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in a ceramic DIP package for highest reliability

• Schottky clamped output structure

Logic Output Optoisolators Applications

• High-reliability industrial control systems
• Military and aerospace applications requiring Class K qualification
• Gate drive interfaces for power modules

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., #200 vs #300) as lead form and packaging differ. Confirm Class K hermetic sealing requirements against project specifications. Check RoHS compliance status via official datasheets. Ensure compatibility with existing DIP-8 footprints. Validate operating temperature ranges for extreme environments.

Logic Output Optoisolators Selection Notes

Select this component when high reliability and hermetic sealing are mandatory. Compare propagation delay and CTR against non-hermetic alternatives if cost is a constraint. Consider the 8-pin DIP footprint constraints. Evaluate thermal dissipation capabilities within the specified temperature range. Verify isolation voltage requirements against the device's rated limits.
