Automotive Intelligent Power Module Optocoupler Small Outline, 5 Leads

Currently Viewing:

The ACPL-M46T-000E automotive optocoupler consists of a AlGaAs LED optically coupled to an integrated high gain photo detector.

Minimized propagation delay difference between devices make these optocouplers excellent solutions for improving automotive inverter efficiency through reduced switching dead time.

Specification and performance plots are given for typical IPM applications.
