PH9400-gatedrive-transformerMeet the new PH9400 series: Pulse Electronics Power BU’s first ever surface mount (SMT), high isolation gate drive transformers.

We’re excited to add this series to our current lineup of quality gate drive transformers, as this particular series was designed to offer a surface mount (SMT) alternative to our existing THT P058xx series. It also boasts up to a 300% increase in volts-second capability.

In a recent press release, Pulse’s own Product Manager, Gerard Healy, stated:

“The compact construction of our PH9400 series allows for a larger core to be used, thereby increasing the volts-second capability, while reducing the size and increasing the creepage distance by 50% in comparison to the existing THT solution.”

PH9400 Key Features

  • Basic & Reinforced Insulation
  • Patented Sidecar Package with 12mm Creepage
  • Up to 5000Vrms Gate to Drive Isolation
  • 600Vrms Voltage Rating
  • IEC 60950, IEC 61558 and IEC 60601 Compliant

PH9400 Applications

Since the PH9400 series offers isolation in IGBT and MOSFET drivers, it is ideal for the following industrial applications:

  • Motor Drive Circuits
  • Solar Inverters
  • Medical Device Power Supplies

PH9400 Mechanicals & Schematics


The PH9400 series transformers are available in T&R packaging with starting prices in the range of $1.25 – $1.49 (FCA HK) with a lead time of eight weeks.
