ACPL-K312-000E

Overview

The ACPL-K312-000E is a logic output optocoupler from the Broadcom ACPL series, designed for gate drive applications. It features a single channel with an SO-8 Stretched package. Key electrical parameters include a maximum propagation delay of 500 ns, rise time of 0.5 us, and fall time of 500 ns. The device supports a forward current of 16 mA with a forward voltage of 1.8 V and a reverse voltage rating of 5 V. It provides an insulation voltage of 3750 Vrms and has a power dissipation of 295 mW. Operating temperatures range from -40 C to +100 C.

Feature Summary

• High peak output current capability up to 2.5A for gate driving
• Enhanced noise immunity for reliable signal transmission
• Fast switching speed suitable for IGBT and MOSFET control

Applications

• IGBT and MOSFET gate driving
• AC and brushless DC motor drives
• Industrial frequency inverters
• Switching power supplies

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and isolation ratings. Ensure compatibility with target thermal management requirements given the 295 mW dissipation limit. Confirm that the SO-8 Stretched package dimensions match the PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required for power electronics. The 3750 Vrms insulation rating suits medium-voltage industrial applications. Consider the 16 mA forward current requirement for driver circuit design. Evaluate the -40 C to +100 C operating range against environmental conditions.

Part Context

Part of the ACPL family focusing on gate drive isolation. Designed to replace older discrete solutions by integrating high-current output stages. Offers improved efficiency in power conversion systems through faster switching characteristics compared to standard logic optocouplers.
