Overview
The ACPL-P346-560E is a high-speed gate drive optocoupler featuring an AlGaAs LED optically coupled to an integrated circuit with a power output stage. It provides a 2.5A output current capability for driving Power, GaN, and SiC MOSFETs. The device offers 3750Vrms isolation voltage in a 6-SO stretched package. Key electrical parameters include a rise time of 8 ns and a fall time of 50 ns. It operates with a forward current of 12 mA and has a forward voltage of 1.5 V. The maximum power dissipation is 250 mW.
Feature Summary
- Integrated 2.5A power output stage for direct gate drive applications
- High-speed switching with 8 ns rise time for efficient signal transmission
- Robust 3750Vrms insulation voltage ensuring safe isolation between circuits
Applications
- Gate drive for Silicon Carbide (SiC) MOSFETs
- Gate drive for Gallium Nitride (GaN) transistors
- Power supply converter control systems
Procurement Notes
Verify the specific suffix '560E' against the manufacturer's official datasheet to confirm pinout configuration and packaging specifications. Ensure compatibility with system isolation requirements by checking the 3750Vrms rating. Confirm that the 2.5A peak output current meets the load demands of the target power switch. Validate operating temperature ranges against application environmental conditions before finalizing procurement.
Selection Notes
Select this component when high-speed isolation is required for wide-bandgap semiconductors like SiC and GaN. The 2.5A output current supports direct driving of medium-power gates without external buffers. Consider the 6-SO stretched package for PCB layout constraints. Compare rise times against other logic output optocouplers if precise timing synchronization is critical for the switching frequency.
Part Context
This part belongs to Broadcom's ACPL-P346 series of gate drive optocouplers. It is designed specifically for modern power electronics requiring fast switching and high reliability. The series integrates the LED and driver IC to simplify design and reduce board space compared to discrete solutions.
Replacement Considerations
The ACPL-W346-560E is a documented substitute within the same product family offering identical 2.5A gate drive performance and isolation characteristics.
