TDK EP9 IGBT Gate Drive Transformers

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 series supports half-bridge or push-pull topologies and features a 2pF low coupling capacity and ≥5mm clearance distance (cumulative and core floating). TDK EP9 IGBT Gate Drive Transformers operate within a 100kHz to 400kHz frequency range and -40°C to +150°C temperature range. These RoHS-compliant and AEC-Q200-qualified 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.
