6N137TVM

Overview

The onsemi 6N137TVM is a high-speed optocoupler featuring an 850 nm AlGaAs LED coupled to a silicon integrated photo-detector logic gate. It provides a single channel with open collector output and Schottky clamping. Key electrical parameters include a data rate of 10 Mb/s, isolation voltage of 5000 Vrms, and typical common-mode rejection of 10 kV/µs. The device operates within a temperature range of -40°C to +85°C, supports a forward current of 10 mA, and delivers a minimum output sink current of 13 mA at 5 mA input.

Feature Summary

• Integrates an 850 nm AlGaAs infrared emitting diode with a silicon high-speed integrated photo-detector logic gate for optical coupling.
• Features an open-collector output configuration allowing wired OR functionality and includes internal noise shielding for superior common-mode rejection.
• Incorporates Schottky clamping on the output stage to enhance switching speed and signal integrity in high-frequency applications.

Applications

• High-speed digital signal isolation in industrial communication interfaces
• Gate drive isolation for power electronics and motor control systems
• Signal transmission between microcontrollers and peripheral devices requiring galvanic isolation

Procurement Notes

Verify the specific suffix (TVM) corresponds to the 8-MDIP through-hole package variant when sourcing. Confirm that the required insulation voltage rating of 5000 Vrms meets system safety standards. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application before finalizing procurement.

Selection Notes

Select this component when high-speed data transfer up to 10 Mb/s is required alongside robust galvanic isolation. The open-collector output is suitable for interfacing with various logic families via external pull-up resistors. Consider the 10 kV/µs common-mode rejection ratio for environments with significant electrical noise or rapid voltage transients.

Part Context

The 6N137TVM belongs to the 6N137M series, which utilizes an AlGaAs LED and silicon photodetector logic gate architecture. This family design distinguishes itself from conventional phototransistor optocouplers by offering significantly improved speed performance. The series ensures consistent coupling parameters across the specified industrial temperature range.

Replacement Considerations

Public confirmed substitutes include HCPL-2601M and HCPL-2611M from Broadcom (formerly Avago). These alternatives share similar high-speed logic output characteristics and pinout compatibility within the DIP-8 form factor.
