ACPL-335J-500E

Overview

The ACPL-335J-500E is a logic output optocoupler designed for gate drive applications. It features an open collector output and operates within a single channel configuration. The device provides an insulation voltage of 5000 Vrms, ensuring robust isolation between input and output circuits. Electrical characteristics include a rise time of 60 ns and a fall time of 50 ns. The forward current rating is 10 mA, with a forward voltage of 1.55 V and a reverse voltage of 6 V. Power dissipation is specified at 580 mW. The component is housed in a SOIC-16 surface mount package and supports operating temperatures from -40°C to +105°C.

Feature Summary

• Integrates an AlGaAs LED with an integrated circuit photodetector for high-speed signal transmission.
• Provides active Miller clamp functionality to prevent false turn-on during high dv/dt events.
• Features fault feedback capability via the open collector output for system monitoring.

Applications

• IGBT gate driving in motor control inverters
• MOSFET gate driving in power conversion circuits
• Industrial automation control systems requiring isolated switching

Procurement Notes

Verify the specific suffix J-500E against the manufacturer datasheet to confirm lead-free status and tape-and-reel packaging specifications. Ensure that the SOIC-16 footprint matches the target PCB design guidelines. Cross-reference the insulation voltage ratings with system safety requirements before finalizing procurement orders.

Selection Notes

Select this component when high common-mode transient immunity is required for IGBT or MOSFET drivers. The open collector output allows flexible interfacing with various logic levels. Consider the thermal management capabilities given the 580 mW power dissipation limit in enclosed environments.

Part Context

This part belongs to the ACPL-33xJ series of intelligent gate drive optocouplers manufactured by Broadcom Limited. These devices are engineered to simplify the design of isolated power stages by integrating protection features directly into the optocoupler package, reducing external component count.

Replacement Considerations
