ACNT-H61L-000E

Overview

The Broadcom ACNT-H61L-000E is a single-channel, high-speed digital optocoupler featuring a stretched SO-8 package with 14.2 mm clearance and 15 mm creepage distance. It delivers a data rate of 10 MBd with typical rise and fall times of 10 ns. The device supports an input forward current range of 4.5 mA to 10 mA and offers an isolation voltage of 7500 Vrms. It operates within a temperature range of -40°C to +105°C and includes a push-pull output stage.

Feature Summary

• Combines a light-emitting diode and integrated high-gain photo detector for low power isolated interface applications
• Features a stretched wide package design providing enhanced safety clearance and creepage distances
• Utilizes a push-pull output stage to ensure fast signal transmission and robust logic level compatibility

Applications

• Industrial communication interfaces requiring galvanic isolation
• Power supply feedback loops in switching mode power supplies
• Microcontroller input/output isolation in embedded systems

Procurement Notes

Verify the specific suffix code to confirm packaging configuration, as variations exist between tape-and-reel and cut-tape formats. Ensure the procurement documentation explicitly references the ACNT-H61L-000E part number to distinguish it from similar ACNT-H61LC variants which may differ in mold compound specifications. Confirm RoHS compliance status through official manufacturer declarations prior to finalizing orders.

Selection Notes

Select this component when high-speed data transfer up to 10 MBd is required alongside strict isolation voltage requirements. The stretched SO-8 package is suitable for designs needing increased PCB spacing for safety standards. Consider the low power consumption profile for battery-operated or thermally constrained environments where standard optocouplers might exceed thermal limits.

Part Context

This device belongs to the Broadcom ACNT series of high-speed digital optocouplers. It is designed to address the need for low-power consumption in isolated digital interfaces while maintaining high reliability. The series utilizes advanced CMOS technology to integrate high-gain photodetectors, enabling faster response times compared to traditional transistor-output optocouplers.

Replacement Considerations

ACNT-H61L-500E serves as a verified alternative variant within the same product family, offering identical electrical performance but potentially differing in packaging format.
