HCPL-675K

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-675K is a quad-channel, hermetically sealed logic output optocoupler from the Broadcom HCPL-6 series. It features a flat-pack 16 package with surface mount installation. The device provides 1500VDC isolation voltage and supports a maximum continuous output current of 40mA per channel. It operates within a temperature range of -55°C to +125°C. Key electrical parameters include a minimum Current Transfer Ratio (CTR) of 200% at 5mA input, a typical propagation delay of 100µs, and a forward voltage of 1.8V. The output type is open collector.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Hermetically sealed construction for environmental stability
• Quad-channel configuration for multi-signal isolation
• High gain capability with CTR up to 1500%
• Surface mount flat-pack design for compact integration

Transistor, Photovoltaic Output Optoisolators Applications

• High-voltage isolation in industrial control systems
• Signal transmission in noisy electromagnetic environments
• Logic interface circuits requiring galvanic isolation
• Medical equipment signal isolation channels

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix and revision level against the latest official datasheet ECAD models before ordering. Confirm that the hermetic seal integrity meets project requirements. Ensure the flat-pack 16 footprint matches the PCB layout exactly. Check for any product change notices affecting pinout or material composition. Validate thermal management capabilities for the intended operating temperature range.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and multiple independent channels are required in a single package. The hermetic seal makes it suitable for harsh environments where standard plastic packages may fail. Consider the 100µs propagation delay when designing timing-critical circuits. The open-collector output requires appropriate pull-up resistors for proper logic level translation.

Transistor, Photovoltaic Output Optoisolators Part Context

The HCPL-675K belongs to the HCPL-6 series of high-gain optocouplers manufactured by Broadcom Limited. This series includes single, dual, and quad-channel variants designed for robust performance. The part is often referenced alongside other hermetic optocouplers like the 6N140A and HCPL-570x in military and aerospace applications due to its sealed construction and reliability standards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the quad-channel, hermetic, flat-pack 16 specification. Verify compatibility with HCPL-6751 if non-hermetic packaging is acceptable. Ensure substitute parts maintain the 1500VDC isolation rating and similar CTR characteristics. Cross-reference with 6N14x series devices only if package differences are resolved.
