HCPL-5201

Logic Output Optoisolators Overview

The HCPL-5201 is a high-reliability, single-channel hermetically sealed optocoupler manufactured by Broadcom Limited. It features a Class H ceramic package with gold-plated leads and operates within a temperature range of -55°C to +125°C. The device provides a data rate of 5 MBd with propagation delays of 350 ns (max) for both rising and falling edges. Key electrical parameters include an isolation voltage of 1500 VDC, a forward current of 8 mA, and an output current of 15 mA. It utilizes a tri-state logic output and offers a common mode transient immunity of 1 kV/µs.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in a Class H ceramic DIP package ensures high reliability and environmental stability.
• Tri-state logic output configuration allows for flexible interfacing with digital systems.
• High-speed performance supports data rates up to 5 MBd with defined propagation delay characteristics.
• Robust insulation capability provides 1500 VDC isolation between input and output circuits.

Logic Output Optoisolators Applications

• Space-qualified electronic systems requiring radiation-hardened or high-reliability components
• Industrial control systems operating in extreme temperature environments
• Military and aerospace instrumentation requiring hermetic sealing

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm exact package dimensions and lead finish specifications. Ensure that the procurement documentation explicitly states the Class H hermetic seal status, as this is critical for space and military applications. Confirm compliance with RoHS directives if required by the end-use environment. Cross-reference the manufacturer part number with authorized distributor lists to ensure authenticity and traceability.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and wide temperature operation are mandatory requirements. The tri-state output is suitable for bus-oriented applications where multiple devices share a common line. Verify that the 5 MBd data rate meets the system timing constraints. Consider the through-hole mounting style and 8-DIP package size during PCB layout design to ensure adequate clearance for the high isolation voltage rating.

Logic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers from Broadcom Limited. It is distinguished by its hermetic ceramic packaging, which differentiates it from standard plastic-packaged variants in the same family. The HCPL-5201 is designed for applications demanding higher reliability than standard commercial-grade optocouplers can provide.

Logic Output Optoisolators Replacement Considerations

Direct replacements must match the hermetic ceramic package and Class H qualification. Standard plastic-packaged HCPL-52xx variants may not meet the environmental requirements. Verify pinout compatibility and electrical parameters such as propagation delay and isolation voltage before substitution.
