ACPL-P343-560E

Overview

The ACPL-P343-560E is a single-channel IGBT gate driver optocoupler from Broadcom's ACPL series. It features a rail-to-rail output voltage and delivers a peak output current of 4A, making it suitable for direct driving of IGBTs rated up to 1200V/200A. The device utilizes an AlGaAs LED input and provides high-speed switching with typical rise and fall times of 43ns and 40ns respectively. It offers 3750Vrms isolation voltage and operates within a temperature range of -40°C to +105°C in a 6-pin SSOP package.

Feature Summary

• Provides 4A peak output current for robust IGBT gate drive capability
• Features rail-to-rail output voltage swing for efficient power stage control
• Integrates high-speed logic output with fast switching characteristics
• Ensures electrical safety with 3750Vrms reinforced isolation barrier

Applications

• Direct driving of IGBT modules in industrial motor drives
• Inverter circuits in renewable energy systems such as solar inverters
• High-power switching applications requiring galvanic isolation
• Solid-state relay designs for heavy-duty load control

Procurement Notes

Verify the specific suffix (e.g., 560E vs 000E) against the datasheet to confirm pinout and packaging variations. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with official Broadcom catalogs to avoid counterfeit components. Confirm that the supplier can provide traceability records for automotive or industrial grade requirements if applicable.

Selection Notes

Select this component when a high peak output current of 4A is required for direct IGBT gate driving without external amplification. The rail-to-rail output simplifies circuit design by eliminating the need for additional level-shifting components. Consider the 3750Vrms isolation rating for applications demanding significant voltage separation between control and power stages. Evaluate the thermal performance within the specified operating temperature range during system integration.

Part Context

This device belongs to Broadcom's ACPL series of high-performance optocouplers designed for power electronics. It complements other gate driver optocouplers like the ACPL-W314 and ACPL-W343 by offering a balance of speed and drive strength. The series is engineered for reliability in harsh electromagnetic environments common in industrial and automotive power conversion systems.
