HCPL-4100-500E

Overview

The HCPL-4100-500E is a single-channel current loop transmitter optocoupler from Broadcom's HCPL series. It features an infrared LED input and an open-collector phototransistor output housed in an 8-SMD Gull Wing package. The device supports a supply voltage range of 4.5V to 20V and operates within a temperature range of -40°C to 85°C. Key electrical specifications include a maximum continuous output current of 30 mA, a typical rise time of 16 ns, and a typical fall time of 23 ns. It provides an isolation voltage of 3750 Vrms and complies with UL 1577 and CSA standards.

Procurement Notes

Verify the specific suffix '500E' confirms the reel packaging format required for surface mount assembly. Confirm that the component status remains active as manufacturing transitions may affect availability. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the datasheet revision date to ensure all electrical parameters match your design requirements before finalizing procurement orders.

Selection Notes

Select this component when designing isolated interfaces requiring 20 mA current loop compatibility. It is suitable for replacing legacy discrete transistor solutions in industrial control environments. Consider the 8-SMD package for automated assembly processes. Verify that the 3750 Vrms isolation rating meets the safety requirements of your specific application environment.

Part Context
