HCPL-1931#100

Logic Output Optoisolators Overview

The HCPL-1931#100 is a high-reliability, hermetically sealed Class H dual-channel optocoupler manufactured by Broadcom Limited. It features a 16-SMD Butt Joint package designed for surface mount applications. The device supports a data rate of 10 Mb/s with open collector outputs clamped by Schottky diodes. Key electrical parameters include a forward current of 10 mA, forward voltage of 2.2 V, and reverse voltage of 1.1 V. Rise and fall times are 30 ns and 24 ns, respectively. It offers an isolation voltage of 1500 Vdc and a common mode transient immunity of 1 kV/µs. Power dissipation is rated at 564 mW, operating within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Feature Summary

• Hermetically sealed ceramic construction ensuring high reliability in harsh environments
• Dual-channel design providing independent signal isolation paths
• Schottky-clamped open collector outputs for enhanced switching speed and noise immunity

Logic Output Optoisolators Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems demanding high common-mode noise rejection
• Medical equipment necessitating strict safety isolation standards

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #100 corresponds to the 16-SMD Butt Joint package configuration rather than standard DIP variants. Confirm RoHS compliance status through official documentation as hermetic packages may have distinct regulatory classifications. Ensure supply chain sources provide valid lot traceability for Class H reliability requirements. Cross-reference datasheet revisions to confirm parameter consistency before integration into final designs.

Logic Output Optoisolators Selection Notes

Select this component when both high-speed performance (10 Mb/s) and extreme environmental reliability are required. The hermetic seal distinguishes it from standard plastic-packaged alternatives suitable for less demanding conditions. Consider the 16-SMD form factor for automated assembly processes. Evaluate the 1500 Vdc isolation rating against system voltage requirements to ensure adequate safety margins for medical or industrial isolation barriers.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-1931 series of high-speed optocouplers. It represents a specialized variant optimized for military, aerospace, or high-reliability industrial sectors where traditional semiconductor failures are unacceptable. The hermetic sealing process differentiates it from commercial-grade equivalents, providing superior protection against moisture and contaminants that could degrade long-term performance in critical applications.

Logic Output Optoisolators Replacement Considerations

Direct replacements must match the hermetic Class H specification and 16-SMD Butt Joint package. Generic non-hermetic optocouplers lack the necessary environmental robustness. Verify pinout compatibility and electrical parameters such as CTR and propagation delay if substituting with other dual-channel devices from different manufacturers.
