6N137#300

Overview

The Broadcom Limited 6N137#300 is a high-speed single-channel optocoupler featuring an integrated open-collector output with Schottky clamp. It provides a data rate of 10 Mb/s and supports a forward current of 10 mA with a typical forward voltage of 1.5 V. The device offers an isolation voltage of 2500 Vrms and operates within a temperature range of -40°C to +85°C. Key timing parameters include a rise time of 24 ns and a fall time of 10 ns, with a maximum power dissipation of 85 mW.

Feature Summary

• Integrates a GaAsP LED with a high-gain photo detector for efficient signal transmission.
• Features an open-collector output stage enhanced by a Schottky clamp to minimize storage time.
• Provides unidirectional signal isolation between input and output circuits.

Applications

• High-speed digital communication interfaces requiring galvanic isolation.
• Industrial control systems needing noise immunity in electrically noisy environments.
• Microprocessor system isolation for reliable data transfer across potential differences.

Procurement Notes

Verify the specific suffix #300 against the manufacturer's latest documentation, as availability may vary significantly from standard variants like the 6N137-300E. Confirm RoHS compliance status, as some sources indicate non-compliance for this specific marking. Ensure the package type matches the required PCB footprint, noting discrepancies between SMD and DIP descriptions in distributor listings.

Selection Notes

Select this component when a 10 Mb/s data rate and open-collector logic output are required. Consider the 2500 Vrms isolation rating for basic safety applications. Evaluate the 10 mA forward current requirement against available drive capabilities. Compare against the HCNW137 series if higher isolation voltages or different packaging options are necessary for the specific design constraints.

Part Context

The 6N137#300 belongs to the 6N137 family of high-speed optocouplers manufactured by Broadcom Limited. This series is designed for applications demanding fast response times and high common-mode rejection. The part integrates the LED and photodetector on a single chip to ensure consistent performance characteristics across the product line.
