Important Notice
Transphorm Gallium Nitride (GaN) Switches provide significant advantages over silicon (Si)
Superjunction MOSFETs with lower gate charge, faster switching speeds and smaller reverse recovery charge. GaN Switches exhibit in-circuit switching speeds in excess of
150 V/ns and can be even pushed up to 500V/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 specific 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 practical rules that should be followed during the evaluation.
When Evaluating Transphorm GaN Switches
DO
DO NOT
Minimize circuit inductance by keeping
traces short, both in the drive and power
loop
Minimize lead length of TO-220 and TO247 package when mounting to the PCB
Twist the pins of TO-220 or TO-247 to accommodate GDS board layout
Use shortest sense loop for probing. Attach the probe and its ground connection
directly to the test points
Use differential mode probe, or probe
ground clip with long wire
March 14, 2016 JH
Use long traces in drive circuit, long lead
length of the devices
