ACPL-336J-500E

Overview

The ACPL-336J-500E is a logic output optocoupler featuring a 2.5 A peak IGBT gate drive capability. It operates with an isolation voltage of 5000 Vrms and supports a supply voltage range of 15 V to 30 V. The device utilizes an open-drain output configuration and includes one channel. Key timing parameters include an 80 ns rise time and a 45 ns fall time. It functions within a temperature range of -40 C to +105 C, with a power dissipation rating of 600 mW and a forward current of 20 mA.

Feature Summary

• Integrates active Miller clamp functionality to prevent false turn-on during high dv/dt switching events
• Includes desaturation detection circuitry for rapid short-circuit protection of connected IGBTs
• Features integrated UVLO (Under Voltage Lock Out) with hysteresis for reliable gate drive operation
• Provides rail-to-rail output swing for direct driving of power MOSFETs and IGBTs

Applications

• Motor control inverter circuits
• Industrial variable frequency drives
• Photovoltaic solar inverters
• High-power IGBT gate driver stages

Procurement Notes

Verify the specific suffix J-500E against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system isolation requirements by checking the VIORM and VIOW values. Confirm that the operating temperature range meets the environmental constraints of the target application before finalizing procurement orders.

Selection Notes

Select this component when a single-channel intelligent gate driver with integrated protection features is required. The 2.5 A output current is suitable for driving IGBTs with moderate gate charge requirements. Consider the SOIC-16 package for surface mount assembly. Evaluate the need for desaturation detection and Miller clamping to simplify external protection circuitry design.

Part Context

This part belongs to the Broadcom ACPL-336J/337J series of intelligent gate drive optocouplers. These devices are designed to replace discrete driver solutions by integrating LED drivers, protection logic, and power output stages into a single isolated package. The series targets applications requiring robust protection against short circuits and Miller-induced turn-ons in high-frequency switching environments.

Replacement Considerations

ACPL-337J-500E offers similar functionality with a higher 4 A output current rating.
