6N137V

Overview

The 6N137V is a high-speed logic output optoisolator manufactured by Isocom Components 2004 LTD. It features a single channel with an open collector output configuration, supporting data rates up to 10Mbps. The device provides electrical isolation of 5000Vrms and offers a common-mode transient immunity (CMTI) of 5kV/µs. Typical rise and fall times are specified at 10ns and 40ns respectively. It operates within a temperature range of -40°C to +85°C and is available in an 8-pin DIP package.

Feature Summary

• High-speed signal transmission capability for digital applications
• Open collector output allows for wired OR logic configurations
• Robust electrical isolation with high common-mode transient immunity

Applications

• Industrial control systems requiring fast signal isolation
• Power supply protection circuits
• Communication interfaces needing high noise immunity

Procurement Notes

Verify the manufacturer designation matches Isocom Components 2004 LTD rather than other historical producers like Fairchild Semiconductor. Confirm the suffix 'V' corresponds to the specific voltage or packaging variant defined in current official documentation. Ensure the datasheet specifies the operating temperature range and isolation ratings relevant to your circuit design requirements before finalizing procurement.

Selection Notes

Select this component when high-speed digital isolation is required alongside open collector output flexibility. The 10Mbps data rate suits applications demanding rapid signal transfer across isolation barriers. Consider the 5kV/µs CMTI for environments with significant electrical noise. The 8-DIP package facilitates through-hole mounting in standard industrial equipment designs.

Part Context

Isocom Components 2004 LTD continues the legacy of high-performance optocouplers originally developed under the Litronix brand. The company specializes in infrared optoelectronic devices, providing alternatives to discontinued industry standards. This part represents their focus on reliable, high-speed isolation solutions for commercial and industrial markets.

Replacement Considerations

This component serves as a direct replacement for the Fairchild Semiconductor 6N137 series. Verify pinout compatibility and electrical parameter equivalence against original specifications. Ensure substitute sources confirm identical isolation voltages and speed characteristics.
