6N137#520

Overview

The Broadcom Limited 6N137#520 is a high-speed optocoupler featuring a single channel with a data rate of 10 Mb/s. It utilizes an open collector output type and supports a maximum forward current of 10 mA with a forward voltage of 1.5 V. The device offers an insulation voltage of 2500 Vrms and can handle a maximum collector current of 50 mA. Operating temperatures range from -40°C to +85°C, with rise and fall times of 24 ns and 10 ns respectively.

Feature Summary

• Integrates a GaAsP light emitting diode with an internal shield for high common mode transient immunity.
• Features an enable input that allows the detector to be strobed for power management.
• Output consists of an open collector Schottky-clamped transistor for TTL compatibility.

Applications

• High-speed digital isolation in industrial control systems
• Signal transmission across isolated boundaries in communication interfaces
• Gate driving circuits requiring fast switching speeds

Procurement Notes

Verify the specific suffix #520 against the official datasheet to confirm lead-free compliance and packaging configuration. Ensure the selected variant matches the required insulation voltage and package style for your design. Cross-reference the manufacturer's latest product change notices to confirm availability and any potential obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when high-speed signal isolation is required alongside robust noise immunity. The integrated enable pin provides additional control over power consumption during idle states. Consider the open collector output requirements for pull-up resistor selection and ensure the operating temperature range aligns with the environmental conditions of the target application.
