Transphorm Announces Two 4-Lead TO-247 Devices, Expanding Product Portfolio for High Power Server, Renewable, Industrial Power Conversion

By: via Business Wire

New FETs Serve as an Original Design Option or Drop-In Replacement for SiC

Transphorm, Inc. (Nasdaq: TGAN), the global leader in robust GaN power semiconductors, today announced availability of two new SuperGaN® devices in a 4-lead TO-247 package (TO-247-4L). The new TP65H035G4YS and TP65H050G4YS FETs offer a 35 mOhm and 50 mOhm on resistance respectively, complete with a kelvin-source terminal that gives customers versatile switching capabilities with even lower energy losses. The new products will run on Transphorm’s well-established GaN-on-Silicon substrate manufacturing process that is cost-effective, reliable, and well-suited for high volume manufacturing on silicon production lines. The 50 mOhm TP65H050G4YS FET is currently available while the 35 mOhm TP65H035G4YS FET is sampling and slated for release in calendar Q1’2024.

Transphorm’s 4-lead SuperGaN devices can serve as an original design-in option or as a drop-in replacement for 4-lead silicon and SiC solutions supporting power supplies at 1 kilowatt and up in a wide range of data center, renewables, and broad industrial applications. As noted, the 4-lead configuration offers flexibility to users for further improved switching performance. In a hard-switched synchronous boost converter, the 35 mOhm SuperGaN 4-lead FET reduced losses by 15 percent at 50 kilohertz (kHz) and by 27 percent at 100 kHz when compared to a SiC MOSFET device with a comparable on resistance.

Transphorm’s SuperGaN FETs are known for delivering differentiating advantages such as:

  • Industry-leading robustness with a +/- 20 V gate threshold and a 4 V noise immunity.
  • Easier designability by reducing the amount of circuitry required around the device.
  • Easier drivability as FETs can pair with well-known, off-the-shelf drivers common to silicon devices.

The TO-247-4L devices offer the same robustness, designability, and drivability with the following core specifications:

“We continue to expand our product portfolio to bring to market GaN FETs that help customers leverage our SuperGaN platform performance advantages in whatever design requirement they may have,” said Philip Zuk, Senior Vice President, Business Development and Marketing, Transphorm. “The four-lead TO-247 package provides flexibility for designers and customers seeking even greater power system loss reductions with little to no design modifications on silicon or silicon carbide systems. It’s an important addition to our product line as we ramp into higher power applications.”
