HCPL-625K

Logic Output Optoisolators Overview

The HCPL-625K is a four-channel high-speed optocoupler housed in a hermetically sealed ceramic flat-pack 16 package. It features Class K reliability with gold-plated leads. The device supports a data rate of 5 Mb/s and provides an isolation voltage of 1500 VDC. Key electrical parameters include a forward current of 8 mA, forward voltage of 1.3 V, and reverse voltage of 3 V. Output characteristics specify an open collector or push-pull configuration with a maximum output current of 15 mA. Power dissipation is rated at 200 mW, operating within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Feature Summary

• Hermetically sealed ceramic flat-pack construction ensuring Class K reliability
• High common-mode transient immunity of 1 kV/µs for noise rejection
• Four independent channels providing isolated signal transmission

Logic Output Optoisolators Applications

• Industrial process control systems requiring high reliability
• Medical equipment demanding strict isolation standards
• Power supply feedback loops in high-voltage environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation to confirm the exact output stage configuration, as datasheets may list variations between open collector and push-pull outputs for this series. Ensure the procurement order specifies the Class K hermetic sealing requirement if intended for radiation-hardened or extreme environment applications. Confirm that the flat-pack 16 package dimensions match the target PCB footprint before finalizing orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside stringent environmental durability. The 5 Mb/s data rate suits moderate-speed communication interfaces. Consider the thermal management capabilities provided by the ceramic package for high-power dissipation scenarios. Verify input current requirements align with the 8 mA specification to ensure proper LED drive conditions without exceeding limits.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-6 series of high-speed optocouplers manufactured by Broadcom Limited. The series is characterized by its use in applications necessitating robust electrical isolation and fast signal propagation. The HCPL-625K specifically addresses needs for multi-channel isolation in compact, hermetically sealed packages suitable for aerospace and military-grade electronics.

Logic Output Optoisolators Replacement Considerations

Direct substitutes are limited due to the specific hermetic Class K packaging. Check for other HCPL-6xxx variants with compatible pinouts and electrical ratings. Verify that any replacement maintains the 1500 VDC isolation rating and 5 Mb/s speed capability.
