ACPL-338J-500E

Overview

The ACPL-338J-500E is a single-channel IGBT gate driver optocoupler manufactured by Broadcom Limited. It features an AlGaAs LED input coupled to an integrated circuit output stage, providing a peak output current of 1.5 A. The device offers high common-mode transient immunity of 50 kV/µs and an isolation voltage of 5000 Vrms. Key functional parameters include propagation delays of 250 ns for both high-to-low and low-to-high transitions. It operates within a temperature range of -40°C to +105°C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates Vce desaturation detection for short-circuit protection
• Includes active Miller clamp to prevent false turn-on
• Features UVLO with hysteresis for reliable operation
• Provides isolated fault feedback signal

Applications

• IGBT gate driving in motor control inverters
• Power MOSFET switching applications
• Industrial power conversion systems
• High-voltage DC transmission interfaces

Procurement Notes

Verify the specific suffix 'J' and '500E' against the manufacturer's latest datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the required packaging format, such as tape and reel or cut tape, as availability varies by distributor. Confirm the operating temperature range requirements align with the specified -40°C to +105°C limit before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring robust IGBT protection with integrated desaturation detection and Miller clamping. The 1.5 A drive capability suits direct driving of moderate-power IGBTs up to 1200 V. Consider the 50 kV/µs CMTI rating for noisy environments. Verify that the 16-pin SOIC footprint fits the PCB layout constraints and that the 250 ns propagation delay meets the system timing requirements.

Part Context

This device belongs to the ACPL-330 series of intelligent gate driver optocouplers from Broadcom. These components are designed to simplify the implementation of IGBT protection schemes in power electronics. The series integrates multiple protection functions typically requiring discrete components, reducing board space and design complexity for industrial and automotive power applications.

Replacement Considerations
