ACPL-5161

Overview

The ACPL-5161 is a hermetic optocoupler featuring a single channel with a 1500 Vrms isolation voltage. It operates within a temperature range of -55°C to +125°C and utilizes a PDIP-16 package. The device provides an open collector output type with a maximum propagation delay of 500 ns. Typical rise and fall times are specified at 100 ns each. The component supports a maximum continuous output current of 2.5 A, with power dissipation ratings of 150 mW or 600 mW depending on configuration.

Feature Summary

• Hermetic packaging for enhanced environmental protection
• High common-mode transient immunity capabilities
• Wide operating temperature range suitable for harsh conditions

Applications

• Industrial motor control systems
• Power supply feedback loops
• Military and aerospace electronic circuits

Procurement Notes

Verify the specific suffix code to confirm hermetic sealing status, as standard plastic variants exist within the same family. Confirm lead times directly with Broadcom Limited distributors, as availability varies by region. Ensure compliance with RoHS3 specifications if required by the end application. Check for any recent PCN updates regarding material changes or manufacturing site transfers before finalizing orders.

Selection Notes

Select this component when hermetic sealing is mandatory for reliability in extreme environments. Compare against non-hermetic alternatives like the ACPL-5160 if cost reduction is prioritized over radiation or moisture resistance. Ensure the open-collector output interface matches the downstream logic requirements. Verify that the 1500 Vrms isolation rating meets the safety standards of the target system design.

Part Context

The ACPL-5161 belongs to the ACPL-516x series of gate drive optocouplers manufactured by Broadcom Limited. This series is designed for high-reliability applications requiring galvanic isolation between control and power stages. The hermetic variant distinguishes itself from standard plastic packages by offering superior protection against humidity and contaminants, making it suitable for long-life mission-critical electronics.

Replacement Considerations

• ACPL-5160 (Non-hermetic equivalent)
• HCPL-5161 (Legacy designation)
