6N137WV

Overview

The onsemi 6N137WV is a high-speed single-channel logic gate optocoupler housed in an 8-MDIP surface-mount package. It supports data rates up to 10 Mbps with typical rise and fall times of 30 ns and 10 ns, respectively. The device features an open collector output capable of sinking 50 mA and provides 2500 Vrms isolation voltage. It operates within a supply voltage range of 4.5 V to 5.5 V and includes Schottky clamping for enhanced noise immunity.

Feature Summary

• High-speed signal transmission capability supporting 10 Mbps data rates
• Integrated Schottky clamping on the output stage to improve noise immunity
• Single-channel design with open collector output configuration
• Compact surface-mount packaging suitable for automated assembly

Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems needing noise-resistant signal transmission
• Power supply feedback loops for isolated monitoring
• Microcontroller input isolation in noisy electromagnetic environments

Procurement Notes

Verify that the specific suffix WV corresponds to the required 8-MDIP surface-mount package variant rather than through-hole DIP options. Confirm RoHS compliance status and ensure the supplier provides official datasheets matching the 6N137 series specifications. Check for any recent product change notices regarding pinout or electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when high-speed isolation is required alongside compact board space constraints. The open collector output necessitates an external pull-up resistor; ensure the chosen resistor value aligns with the target switching speed and load requirements. Verify that the operating temperature range meets the application's environmental conditions and that the isolation voltage rating exceeds the system's safety requirements.

Part Context

The 6N137WV belongs to the broader 6N137/HCPL-2631 family of high-speed logic gate optocouplers from onsemi. This family is designed to replace slower optocouplers in applications demanding faster response times. The WV suffix specifically denotes the surface-mount version, distinguishing it from other package styles like the standard DIP variants within the same functional family.

Replacement Considerations

Direct replacements include the HCPL-2631 and HCPL-2630 series devices from onsemi, which share identical pinouts and electrical characteristics. Other manufacturers may offer functionally equivalent parts, but careful verification of pin compatibility and isolation ratings is essential to ensure seamless integration without circuit redesign.
