Important Notice

Transphorm Gallium Nitride (GaN) Switches provide significant advantages over silicon (Si)

Superjunction MOSFETs with lower gate charge, faster switching speeds and smaller re-

verse recovery charge. GaN Switches exhibit in-circuit switching speeds in excess of

100 V/ns compared to current silicon technology usually switching at rates less than 50V/ns.

The fast switching of GaN devices reduces current-voltage cross-over losses and enables

high frequency operation while simultaneously achieving high efficiency. However, taking full

advantage of the fast switching characteristics of GaN Switches requires adherence to spe-

cific PCB layout guidelines and probing techniques .

Transphorm suggests visiting application note “Printed Circuit Board Layout and Probing for

GaN Power Switches” before evaluating Transphorm GaN switches. Below are some practi-

cal rules that should be followed during the evaluation.

When Evaluating Transphorm GaN Switches

DO NOT

Minimize circuit inductance by keeping

traces short, both in the drive and power

loop

Twist the pins of TO-220 or TO-247 to ac-

commodate GDS board layout

Minimize lead length of TO-220 and TO-

247 package when mounting to the PCB

Use long traces in drive circuit, long lead

length of the devices

Use shortest sense loop for probing. At-

tach the probe and its ground connection

directly to the test points

Use differential mode probe, or probe

ground clip with long wire
