ACPL-332J-000E

Overview

The ACPL-332J-000E is a logic output optocoupler from Broadcom Limited, designed for IGBT gate drive applications. It features a single channel in a surface-mount SOIC-16 package. Key electrical parameters include a rise time of 50 ns and a fall time of 50 ns. The device supports a maximum continuous output current of 2.5 A with a forward current of 25 mA. Isolation voltage is rated at 3750 Vrms or 5 kV depending on the specification source. Operating temperature ranges from -40 °C to +105 °C, with power dissipation specified between 600 mW and 1200 mW.

Feature Summary

• Integrated high-current output stage capable of driving IGBT gates directly without external components.
• Provides galvanic isolation between control circuitry and high-voltage power stages.
• Features fast switching speeds suitable for high-frequency pulse width modulation applications.

Applications

• Insulated Gate Bipolar Transistor (IGBT) gate drive circuits
• Industrial motor control systems
• Power supply isolation interfaces

Procurement Notes

Verify the specific datasheet revision and isolation voltage rating (3750 Vrms vs 5 kV) as sources vary. Confirm RoHS compliance status through official manufacturer documentation. Ensure the SOIC-16 package dimensions match the target PCB footprint. Check for automotive qualification requirements if used in vehicle applications, as this part may not be AEC-Q100 certified unlike other variants in the series.

Selection Notes

Select this component when direct IGBT driving capability is required within a single-channel isolated interface. Compare against the ACPL-32JT-000E if automotive qualification or different switching speed characteristics are needed. Verify that the 2.5 A output current meets the load requirements of the connected power device. Consider thermal management constraints given the power dissipation limits in enclosed environments.

Part Context

This device belongs to the Broadcom ACPL series of optocouplers, which are widely used in industrial and consumer electronics for signal isolation. The ACPL-332J variant specifically targets power electronics applications requiring robust gate drive signals. It complements other Broadcom isolation products by offering integrated driver functionality rather than simple logic transmission.

FAQ

What is the typical propagation delay of the ACPL-332J-000E?

Official datasheets specify rise and fall times of 50 ns each, but explicit propagation delay values are not consistently provided across all public documentation sources.

Is the ACPL-332J-000E qualified for automotive applications?

Unlike the ACPL-32JT-000E which carries AEC-Q100 qualification, the ACPL-332J-000E is generally categorized for industrial use without explicit automotive certification in standard listings.
