EP9 IGBT Gate Drive Transformers

EPCOS/TDK EP9 IGBT Gate Drive Transformers are compact devices built on an MnZn ferrite core with an SMD L-pin construction.These transformers offer excellent insulation, minimal coupling capacitance, and high thermal resilience. The EP9 IGBT gate drive transformers support half-bridge or push-pull topologies. These transformers feature a 2pF low coupling capacity and ≥5mm clearance distance (cumulative and core floating). The EP9 IGBT gate drive transformers operate within the 100kHz to 400kHz frequency range and -40°C to 150°C temperature range. These transformers are RoHS compliant and AEC-Q200 qualified. The EP9 IGBT gate drive transformers are designed specifically for IGBT and FET gate driver circuits. Typical applications include isolated DC-DC converters, isolated AC-DC converters, and gate driver circuits.
