ACNT-H61LC-500E

Overview

The Broadcom ACNT-H61LC-500E is a high-speed, single-channel digital CMOS optocoupler housed in a 15mm stretched SO-8 package. It features a data rate of 10 MBd and an isolation voltage of 7500 Vrms. The device utilizes a push-pull totem pole output with a typical rise/fall time of 10 ns. Operating parameters include a forward current of 10 mA, forward voltage of 1.38 V, and reverse voltage of 5 V. Power dissipation is rated at 42 mW. It supports a supply voltage range of 2.7V to 5.5V and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a light-emitting diode with an integrated high-gain photo detector for signal transmission.
• Features a low-power digital CMOS architecture designed for efficient operation.
• Provides high common-mode transient immunity (CMTI) of 20 kV/µs.

Applications

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

Procurement Notes

Verify the specific suffix '500E' corresponds to the tape and reel packaging configuration as indicated by distributor listings. Confirm that the 15mm stretched SO-8 package dimensions meet your PCB footprint requirements. Ensure the CTI 600V rating aligns with your insulation coordination standards. Cross-reference the RoHS compliance status with current regulatory requirements for your target market.

Selection Notes

Select this component when high-speed data transmission up to 10 MBd is required alongside robust electrical isolation. The 15mm stretched package offers improved creepage distance compared to standard SO-8 variants. Consider the push-pull output capability for driving loads directly without additional pull-up resistors. Evaluate the 7500 Vrms isolation barrier for safety-critical applications requiring strict galvanic separation.

Part Context

This part belongs to the Broadcom ACNT-H61L series of wide-body optocouplers. The 'LC' designation typically indicates specific mold compound characteristics, such as the CTI 600V rating mentioned in product descriptions. The '-500E' suffix denotes the specific packaging format, often associated with tape and reel delivery for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications before considering any alternative components from other manufacturers or different series within the same family.
