The ACPL-334J and ACPL-338J are 3A gate drive optocouplers with integrated IGBT protection and fault reporting. These devices feature common mode transient immunity (CMTI) greater than 100 kV/μs and provide minimal propagation delay with excellent timing skew. The high peak output current and wide operating voltage range eliminates the need for an output buffer circuit, enabling designers to implement cost-effective isolated gate drive solutions for motor drives and power inverters.

Packaged in a compact, surface-mountable SO-16 package, ACPL-334J and ACPL-338J are a pin-to-pin upgrades for the ACPL-332J (with non-automatic FAULT reset) and ACPL-338J (with automatic FAULT reset) respectively. They are certified to provide reinforced galvanic isolation with 1,414VPEAK working voltage meeting safety regulatory IEC/EN/DIN, UL, and CSA.
