6N137S(TA)

Overview

The 6N137S(TA) is a high-speed optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with an open collector output type, designed for DC input applications. The device supports a data rate of 10 Mb/s and provides an isolation voltage of 2500 Vrms. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.4 V, and a reverse voltage of 5 V. The output can handle a maximum current of 50 mA with a power dissipation of 100 mW. Transition times are specified at 75 ns for both rise and fall. The component operates within a temperature range of -40°C to +85°C and is housed in an SMD-8 package.

Feature Summary

• High-speed signal transmission capability supporting up to 10 Mb/s data rates
• Open collector output configuration for flexible logic interfacing
• Robust electrical isolation with 2500 Vrms insulation voltage rating

Applications

• High-speed digital communication interfaces
• Logic gate output isolation circuits
• Industrial control system signal coupling

Procurement Notes

Verify the specific suffix (TA) against the manufacturer's official datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure that the SMD-8 package dimensions match the target PCB footprint requirements. Cross-reference the isolation voltage rating with system safety standards before integration into high-voltage environments.

Selection Notes

Select this component when a balance between moderate speed (10 Mb/s) and cost-effectiveness is required. The open collector output necessitates an external pull-up resistor, which should be considered during circuit design. Compare transition times against system timing constraints to ensure signal integrity is maintained at the desired operating frequency.

Part Context

This part belongs to the 6N137 series of high-speed optocouplers. Variants such as 6N137S(TB) share similar electrical characteristics but differ in packaging or reel specifications. The series is widely used in applications requiring galvanic isolation between low-voltage logic circuits and higher-voltage domains while maintaining fast signal propagation speeds.
