6N137SDV

Overview

The onsemi 6N137SDV is a high-speed logic gate optocoupler featuring an 8-SMD surface-mount package. It provides one channel with a data rate of 10 Mbit/s and an isolation voltage of 2500 Vrms. The device utilizes a DC input type and delivers a photo IC output with an open collector configuration. Key electrical parameters include a maximum forward current of 50 mA, a typical forward voltage of 1.45 V, and an output current capability of 50 mA per channel. Power dissipation is rated at 100 mW, with rise and fall times of 30 ns and 10 ns respectively.

Feature Summary

• High-speed signal transmission capability supporting 10 Mbit/s data rates for efficient digital communication.
• Integrated logic gate structure simplifies circuit design by providing direct logic-level output compatibility.
• Robust electrical isolation ensures safety and noise immunity between input and output circuits.

Applications

• High-speed serial communication interfaces requiring galvanic isolation
• Digital signal processing systems needing fast transient response
• Industrial control applications with strict isolation requirements

Procurement Notes

Verify the specific suffix designation to confirm the exact packaging variant, as the base model may correspond to different tape-and-reel or cut-tape specifications depending on the distributor. Ensure that the procurement documentation explicitly references the 8-SMD package and the 2500 Vrms isolation rating to match system requirements. Cross-reference the manufacturer part number against official onsemi databases to avoid confusion with similar high-speed optocoupler families.

Selection Notes

Select this component when a balance of moderate speed (10 Mbit/s) and compact surface-mount form factor is required. It is suitable for designs where standard logic gate outputs are preferred over simple transistor outputs. Consider the 8-SMD footprint constraints and verify thermal dissipation capabilities within the target application environment. Compare against higher-speed alternatives if data rates exceed 10 Mbit/s or if through-hole mounting is necessary.

Part Context

The 6N137SDV belongs to the broader family of high-speed logic gate optocouplers manufactured by onsemi. It shares functional similarities with other devices in the series but is distinguished by its specific surface-mount packaging and isolation voltage rating. This part serves as a bridge between low-voltage digital logic and isolated power stages, offering a reliable solution for noise-sensitive environments where physical separation is critical for system integrity.
