6N137S1(TA)

Overview

The Everlight 6N137S1(TA) is a high-speed logic gate optocoupler featuring an open collector output. It supports data rates up to 10Mbps with a response time of 40ns. The device provides 5000Vrms isolation voltage and a common mode transient immunity (CMTI) of 5kV/µs. It operates within a temperature range of -40°C to +85°C, accepts DC input, and utilizes an 8-SMD package.

Feature Summary

• High-speed signal transmission capability supporting 10Mbps data rates
• Robust electrical isolation with 5000Vrms voltage rating
• Open collector output configuration for flexible logic interfacing
• High common mode transient immunity ensuring reliable operation in noisy environments

Applications

• High-speed digital communication interfaces
• Microprocessor system isolation
• Industrial control circuit protection
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'TA' against the manufacturer's latest datasheet to confirm tape-and-reel packaging requirements if applicable. Ensure the operating temperature range meets your environmental specifications. Cross-reference the pinout diagram with your PCB footprint design to prevent orientation errors during assembly. Confirm that the open collector output voltage limits align with your downstream logic level requirements.

Selection Notes

Select this component when high-speed data transfer is required alongside strong galvanic isolation. The open collector output allows for voltage level shifting but requires an external pull-up resistor. Consider the 5000Vrms isolation barrier for safety-critical applications. Evaluate the 10Mbps speed limit against your system's maximum data rate needs before choosing alternative faster or slower variants.

Part Context

This part belongs to the 6N137 series of high-speed logic gate optocouplers manufactured by Everlight Electronics. The series is designed for applications requiring fast signal transmission between isolated circuits. The 6N137S1(TA) variant specifically denotes the surface-mount package configuration and specific testing or packaging parameters defined by the manufacturer for this channel count and output type.

Replacement Considerations

Direct replacements include other 10Mbps single-channel logic output optocouplers with similar isolation ratings. Verify pin compatibility and output configuration (open collector) before substituting. Check datasheets for equivalent CMTI and propagation delay specifications to ensure performance parity in high-speed designs.
