ACPL-330J-500E

Overview

The ACPL-330J-500E is a single-channel IGBT gate drive optocoupler featuring an AlGaAs LED and integrated circuit output. It provides a peak output current of 1.5 A with a propagation delay of 250 ns (tpHL/tpLH). The device offers 5000 Vrms isolation voltage and a common-mode transient immunity of 50 kV/µs. Rise and fall times are typically 50 ns. It operates within a temperature range of -40°C to +105°C in a 16-SOIC package.

Feature Summary

• Integrates Vce desaturation detection for short-circuit protection
• Includes under-voltage lockout (UVLO) with hysteresis
• Features active Miller clamp to prevent false turn-on
• Provides isolated collector-open fault feedback signal

Applications

• IGBT gate driving in motor control inverters
• Power supply switching applications
• Industrial inverter circuits
• High-power MOSFET and IGBT driver interfaces

Procurement Notes

Verify the specific suffix 'J' indicates the correct insulation rating and packaging configuration. Confirm that the 5000 Vrms isolation specification meets the safety requirements of the target application. Ensure the SOIC-16 narrow package dimensions align with the PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when high-speed switching with integrated protection is required. The 1.5 A output current suits direct driving of smaller IGBTs or driving external stages for larger devices. Consider the 50 kV/µs CMTI for noisy environments. Compare against higher current variants like the ACPL-333J if greater drive strength is necessary.

Part Context

This part belongs to the Broadcom ACPL-33 series of intelligent gate drive optocouplers. These devices combine optical isolation with power output stages and diagnostic features. The series is designed to simplify the design of robust power electronic systems by integrating protection logic directly into the isolation barrier, reducing external component count.

Replacement Considerations

ACPL-33JT-500E is a listed alternative with similar specifications but may differ in automotive qualification status or specific timing parameters. Verify pinout compatibility and electrical characteristics before substitution.
