TDK unveils a more compact gate driver transformer series for 500 V systems

Engineered for high performance in demanding e-mobility and industrial applications with 500 V system voltage, these components offer exceptional insulation, minimal coupling capacitance, and high thermal resilience. With this new series, TDK is driving the green transformation towards a more electric and sustainable future.

The EP9 series is built on a MnZn ferrite core with SMD L-pin construction, delivering a height of just 11 mm and a footprint of 13 x 11 mm. These transformers operate across a wide temperature range of −40 °C to +150 °C, ensuring durability under harsh conditions. With a coupling capacitance of only 2 pF, complying with the AEC-Q200 Rev. E standard, and creepage and clearance of at least 5 mm, these surface-mount components are generally used in automotive applications and other demanding environments.




The transformers support topologies such as half-bridge and push-pull converters with typical operational frequency of 100 to 400 kHz and turns ratios optimized for specific applications. These components are available in tape-and-reel packaging, ensuring ease of assembly for high-volume production environments.

A sample kit is available under order number B82804X1, containing six transformers of each version.
