HCNW137-500E

Logic Output Optoisolators Overview

The HCNW137-500E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a single channel with an open collector, Schottky-clamped output capable of sinking up to 50 mA. The device supports data rates of 10 MBd with typical propagation delays of 100 ns and rise/fall times of 24 ns/10 ns. It provides 5000 Vrms isolation voltage and a common-mode transient immunity of 5 kV/µs. Operating on a supply voltage of 4.5V to 5.5V, it is housed in an 8-SMD, gull-wing package suitable for surface-mount applications.

Logic Output Optoisolators Feature Summary

• Integrates a Schottky-clamped phototransistor output to minimize storage time and enhance switching speed.
• Provides robust electrical isolation with 5000 Vrms dielectric strength between input and output circuits.
• Delivers high common-mode transient immunity of 5 kV/µs to maintain signal integrity in noisy environments.

Logic Output Optoisolators Applications

• High-speed serial communication interfaces
• Industrial process control systems
• Power supply feedback loops

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' confirms the RoHS3 compliant status and surface-mount gull-wing packaging configuration. Ensure the procurement order explicitly requests the tape-and-reel or cut-tape variant rather than the tube-packaged through-hole version. Confirm the manufacturer source is Broadcom Limited to avoid counterfeit components.

Logic Output Optoisolators Selection Notes

Select this component when surface-mount assembly is required alongside high-speed digital isolation needs. The 10 MBd data rate and low propagation delay make it suitable for faster protocols compared to standard optocouplers. Verify that the 5000 Vrms isolation rating meets the safety requirements of the target application circuit design.

Logic Output Optoisolators Part Context

This part belongs to the HCNW137 series of high-speed optocouplers from Broadcom Limited. It serves as the surface-mount equivalent to the through-hole HCNW137-000E, sharing identical electrical characteristics but differing in package type and compliance status. The series is designed for applications requiring fast switching and reliable galvanic isolation.
