6N137S

Overview

The 6N137S is a high-speed optocoupler manufactured by Lite-On Inc., housed in an SMD-8 package. It features one channel with a data rate of 15 Mb/s and an isolation voltage of 2500 Vrms. The device utilizes an open collector output capable of 50 mA, driven by a forward current of 10 mA at 1.38 V. Key timing parameters include a rise time of 50 ns and a fall time of 12 ns. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• High-speed logic gate output for efficient signal transmission
• Open collector configuration supporting up to 50 mA output current
• Robust AC and DC isolation capabilities

Applications

• High-speed digital communication interfaces
• Logic circuit isolation
• Signal transmission in noisy environments

Procurement Notes

Verify the specific suffix against official Lite-On documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required SMD-8 package dimensions and thermal dissipation limits. Cross-reference datasheet values for reverse voltage and power dissipation before finalizing component selection.

Selection Notes

Select this component when high-speed data rates near 15 Mb/s are required alongside compact surface-mount integration. The open collector output necessitates an external pull-up resistor for proper logic level generation. Evaluate the 2500 Vrms isolation rating against system safety requirements and ensure operating temperatures remain within the specified industrial range.

Part Context

This part belongs to the 6N137 series of high-speed photocouplers from Lite-On. The series typically includes both DIP and SMD variants, such as the through-hole 6N137. The 'S' designation specifically indicates the surface-mount package form factor, distinguishing it from standard DIP versions while maintaining similar functional performance profiles.
