6N137SV

Overview

The 6N137SV is a high-speed optocoupler from onsemi, featuring an AlGaAs infrared emitter coupled to a silicon integrated photo-detector logic gate. It provides a strobable output in an 8-SMD package. Key electrical parameters include a data rate of 10 Mb/s and an isolation voltage of 2500 Vrms. The device supports an open collector output type with a maximum output current of 50 mA. Typical rise and fall times are 30 ns and 10 ns, respectively. The forward voltage is 1.4 V at a forward current of 10 mA. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates an AlGaAs infrared emitting diode with a silicon high-speed integrated photo-detector logic gate for fast signal transmission.
• Features a strobable output mechanism to enhance noise immunity and signal integrity in high-speed digital applications.
• Provides galvanic isolation between input and output circuits with a robust insulation voltage rating.

Applications

• High-speed digital communication interfaces requiring signal isolation
• Industrial control systems with noisy electromagnetic environments
• Power supply feedback loops for isolated voltage sensing

Procurement Notes

Verify the specific suffix 'SV' against the manufacturer's official datasheet to confirm the exact pinout, tape-and-reel specifications, and RoHS compliance status. Ensure the selected variant matches the required surface-mount package dimensions and thermal characteristics for your PCB layout. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 10 Mbps data rate and 2500 Vrms isolation are sufficient for the application. Consider the open-collector output configuration and required pull-up resistor values for logic level compatibility. Evaluate the 8-SMD package size constraints against available board space. Compare performance metrics with alternative high-speed optocouplers if higher isolation voltages or different output types are needed.

Part Context

The 6N137SV belongs to the broader 6N137 series of high-speed optocouplers manufactured by onsemi. This series is designed for applications demanding rapid signal transfer across isolation barriers. The SV suffix typically denotes a specific surface-mount package variant within the family, differing from through-hole DIP versions like the 6N137TVM. The series leverages advanced LED and photodetector technology to achieve superior speed compared to standard transistor-output optocouplers.

Replacement Considerations

Public confirmed substitute part numbers: 6N137TSVM (onsemi), HCPL-2630 (Broadcom). Verify pinout compatibility and electrical parameter equivalence before substitution.
