Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix '100' corresponds to the butt-joint lead configuration and gold plating, as other suffixes may indicate different physical packages such as gull-wing leads. Confirm compliance with MIL-PRF-38534 Class H requirements if used in defense applications. Ensure the supplier provides traceability documentation for the hermetic seal integrity. Check for recent Product Change Notifications (PCN) regarding material or process updates. Validate that the component is sourced from authorized Broadcom distribution channels to guarantee authenticity.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and low power consumption are required for digital signal transmission. The 3.3V logic compatibility makes it suitable for modern microcontroller interfaces. Consider the hermetic package only if environmental sealing is mandatory, as surface-mount alternatives exist within the series. Evaluate the 1500 VDC isolation rating against system safety standards. The dual-channel architecture allows for cost-effective implementation of isolated bidirectional data links.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ACPL-5731L series of high-reliability optocouplers produced by Broadcom. The series is distinguished by its use of identical chips for transmitters and detectors within each device, ensuring parameter consistency. Unlike standard commercial optocouplers, these devices undergo rigorous screening processes to meet military specifications. The family includes variants with different lead configurations, but all share the same core semiconductor die and electrical performance profile.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the hermetic ceramic DIP-8 package and butt-joint lead style. HCPL-5731 is a similar logic output optocoupler but typically uses plastic packaging and may not meet the same hermetic reliability standards. Verify pinout compatibility and ensure the replacement maintains the 1500 VDC isolation rating and 3.3V operation capability.

Transistor, Photovoltaic Output Optoisolators FAQ

What is the difference between the ACPL-5731L-100 and ACPL-5731L-300?

The primary difference lies in the lead configuration. The ACPL-5731L-100 features butt-joint leads with gold plating, while the ACPL-5731L-300 typically uses gull-wing leads. Both share the same electrical characteristics and hermetic ceramic packaging.

Does the ACPL-5731L-100 support surface mount technology?

No, the ACPL-5731L-100 is designed for through-hole mounting using its butt-joint leads. Surface mount versions within the same series, such as the ACPL-5731L-300, utilize gull-wing leads for SMT assembly.
