ACPL-177KL-300

Transistor, Photovoltaic Output Optoisolators Overview

The ACPL-177KL-300 is a high-reliability, Class K quad-channel logic output optocoupler manufactured by Broadcom Limited. It features a hermetically sealed ceramic DIP package with gold-plated or solder-immersion leads. The device operates within a military temperature range of -55°C to +125°C and complies with MIL-PRF-38534 standards. Each channel utilizes a GaAsP LED coupled to a high-gain photodetector with an open-collector output. It supports a minimum supply voltage of 3.0V and provides an isolation voltage of 1500Vdc.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Hermetically sealed ceramic DIP construction for maximum environmental protection
• Military-grade reliability compliant with MIL-PRF-38534 Class K specifications
• High-gain integrated photodetector with open-collector outputs for low saturation voltage
• Operational stability across the full military temperature spectrum

Transistor, Photovoltaic Output Optoisolators Applications

• Military and aerospace systems requiring high reliability
• Microprocessor system interfaces in harsh environments
• Medical equipment demanding strict isolation standards
• Industrial control systems with high noise immunity needs

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific order explicitly references MIL-PRF-38534 Class K compliance and hermetic sealing capabilities. Confirm the lead type selection, such as gold-plated or solder-immersion variants, matches the assembly requirements. Ensure the supplier provides valid traceability documentation for military-grade components. Cross-check the part number suffix against official Broadcom datasheets to confirm the quad-channel configuration and voltage ratings.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when mission-critical applications demand hermetic sealing and extended temperature operation beyond commercial limits. The open-collector output design offers lower saturation voltage compared to traditional Darlington configurations. Consider this model for systems requiring robust isolation in high-noise industrial or aerospace environments where standard plastic packages are insufficient.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the ACPL-177 series of high-reliability optocouplers. It is distinct from commercial variants like the ACPL-1772L due to its hermetic ceramic packaging and adherence to military performance standards. The series includes single, dual, and quad-channel options, with the ACPL-177KL-300 specifically providing four isolated channels in a 16-pin configuration.
