HCPL-4100-300E

Overview

The HCPL-4100-300E is a single-channel optocoupler designed for current loop transmitter applications. It features an 8-pin DIP surface-mount package with logic output. The device provides 3750Vrms isolation voltage and operates within a temperature range of -40°C to 85°C. It supports simplex point-to-point 20 mA current loops, offering high-speed performance with typical rise and fall times suitable for industrial communication interfaces.

Feature Summary

• Designed specifically as an isolated transmitter for 20 mA current loop systems
• Provides galvanic isolation between input and output circuits
• Features logic output configuration for digital signal transmission

Applications

• Simplex point-to-point 20 mA current loop transmitters
• Industrial process control signal isolation
• Digital communication interface isolation

Procurement Notes

Verify the specific suffix (e.g., 300E) to confirm the tape-and-reel or tube packaging format required for your assembly line. Ensure the component meets all relevant safety certifications such as UL and CSA for your target market. Confirm that the surface-mount DIP package dimensions align with your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when isolating 20 mA current loop signals in simplex configurations. It is suitable for applications requiring robust galvanic isolation and fast switching speeds. Consider the surface-mount package type for automated assembly processes. Verify that the operating temperature range meets the environmental requirements of the intended deployment location.

Part Context

This part belongs to the Broadcom HCPL series of optocouplers, which are widely used in industrial and commercial electronics for signal isolation. The HCPL-4100 variant is specialized for current loop transmitter duties, distinguishing it from general-purpose logic gate optocouplers within the same family.

Replacement Considerations

Check datasheets for other HCPL-4100 variants with different suffixes to match packaging needs. Compare electrical characteristics of alternative current loop transmitters if pin compatibility is not guaranteed.
