ACPL-H342-500E

Overview

The ACPL-H342-500E is a single-channel IGBT gate drive optocoupler featuring a 2.5A peak output current and integrated active Miller clamp. It provides 3750Vrms isolation voltage with a typical rise time of 22ns and fall time of 18ns. The device operates within a -40°C to 105°C temperature range, supports supply voltages from 15V to 30V, and includes under-voltage lockout. It utilizes a stretched 8-SOIC package for enhanced creepage distance.

Feature Summary

Integrated active Miller clamp prevents false turn-on in high dv/dt environments
High common-mode transient immunity ensures reliable signal transmission
Built-in under-voltage lockout protects against improper gate driving conditions

Applications

Insulated Gate Bipolar Transistor (IGBT) gate drive circuits
Variable-speed motor drives and inverters
Electric vehicle powertrain control systems
Induction cooking appliance power modules

Procurement Notes

Verify the specific suffix matches the required packaging configuration. Confirm that the component meets RoHS3 compliance standards for the target market. Ensure the supplier provides valid UL and CSA certification documentation. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when high-speed switching and robust noise immunity are critical. The integrated active Miller clamp eliminates the need for external clamping diodes. Verify that the 3750Vrms isolation rating satisfies the system's safety clearance requirements. Consider the 2.5A output capability for direct IGBT driving applications.
