HCPL-1931#200

Logic Output Optoisolators Overview

The HCPL-1931#200 is a high-reliability, dual-channel hermetically sealed optocoupler designed for Class H applications. It features a ceramic DIP-16 package and provides an isolation voltage of 1500 Vdc. The device operates with a data rate of 10 Mb/s and includes Schottky clamping on the output stage to enhance switching performance. Key electrical parameters include a forward current of 10 mA, a forward voltage of 2.2 V, and a reverse voltage of 1.1 V. The output type is open collector with a maximum output current of 25 mA. Rise and fall times are specified at 30 ns and 24 ns respectively. The unit supports a power dissipation of 564 mW and functions within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in a ceramic DIP package ensures high reliability and environmental protection.
• Integrated Schottky clamping on the output stage improves switching speed and signal integrity.
• Dual-channel design allows for independent signal transmission within a single component.

Logic Output Optoisolators Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems demanding high common-mode transient immunity
• Class H certified equipment where hermetic sealing is mandatory

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #200 corresponds to the CDIP-16 package variant when sourcing. Confirm that the hermetically sealed ceramic construction aligns with the required environmental standards for the target application. Ensure compatibility with the specified operating temperature range and isolation voltage requirements before finalizing procurement.

Logic Output Optoisolators Selection Notes

Select this component when both high-speed data transmission and robust physical isolation are required. The dual-channel configuration reduces board space compared to single-channel alternatives. Consider the ceramic package size constraints and the need for Schottky-clamped outputs to minimize propagation delay variations in high-frequency circuits.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-1931 series of high-speed line receiver optocouplers. It is manufactured by Broadcom Limited (formerly Avago). The series is characterized by its use in demanding environments where standard plastic packages may fail due to moisture or mechanical stress.

Logic Output Optoisolators Replacement Considerations

Direct substitutes must match the 16-pin ceramic DIP footprint and dual-channel architecture. Verify that any replacement maintains the 1500 Vdc isolation rating and 10 Mb/s data rate. Check if alternative parts offer similar Schottky clamping features to ensure comparable switching performance.
