6N137-020E

Overview

The Broadcom Limited 6N137-020E is a high-speed, single-channel optocoupler featuring an open collector output. It supports data rates up to 10 Mb/s with a typical rise time of 24 ns and fall time of 10 ns. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 1 kV/µs. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin PDIP package.

Feature Summary

• High-speed digital isolation capability for fast signal transmission
• Integrated Schottky clamped output stage for enhanced performance
• TTL-compatible input interface for direct logic connection
• High common-mode transient immunity for noise rejection

Applications

• Digital isolation in microprocessor systems
• Signal coupling in industrial communication networks
• Gate drive circuits for power electronics
• Data acquisition systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix '020E' to confirm RoHS compliance and lead-free status as per manufacturer specifications. Ensure the procurement channel sources authentic Broadcom Limited components to avoid counterfeit risks. Confirm that the PDIP-8 through-hole package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when high-speed digital isolation exceeding standard optocoupler limits is required. The open collector output necessitates an external pull-up resistor; ensure the supply voltage aligns with the 50 mA maximum collector current rating. Consider the 5000 Vrms isolation barrier for applications demanding robust safety separation between circuit domains.

Part Context

The 6N137 series represents a family of high-speed optocouplers designed for demanding digital isolation applications. The 6N137-020E variant specifically denotes the RoHS-compliant version manufactured by Broadcom Limited. This part continues the legacy of reliable, fast-switching optoisolators widely used in industrial and commercial electronic designs.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the 6N137 series or equivalent high-speed optocouplers from other manufacturers, provided they match the 10 Mb/s speed, open collector output, and PDIP-8 package constraints.
