ISL70020SEH, ISL73020SEH
40V, 65A Enhancement Mode GaN Power Transistors
The ISL70020SEH and ISL73020SEH are 40V
N-channel enhancement mode GaN power
transistors. These GaN FETs have been
characterized for destructive Single Event Effects
(SEE) and tested for Total Ionizing Dose (TID)
radiation. Applications for these devices include
commercial aerospace, medical, and nuclear power
generation.
Features
• Very low r
3.5mΩ (typical)
DS(ON)
• Ultra low total gate charge 19nC (typical)
• ISL70020SEH radiation acceptance testing
○ High dose rate (50-300rad(Si)/s): 100krad(Si)
○ Low dose rate (0.01rad(Si)/s): 75krad(Si)
• ISL73020SEH radiation acceptance testing
○ Low dose rate (0.01rad(Si)/s): 75krad(Si)
• SEE hardness (see the SEE report for details)
The exceptionally high electron mobility and low
temperature coefficient of the GaN allows for very low
r
, while its lateral device structure and majority
DS(ON)
carrier diode provide exceptionally low Q and zero
G

higher switching frequency with more efficiency while
reducing the overall solution size.
• Ultra small hermetically sealed 4 Ld Surface Mount
Device (SMD) package
By combining the exceptional performance of the
GaN FET in a hermetically sealed Surface Mount
Device (SMD) package with manufacturing in a
MIL-PRF-38535 like flow results in best-in-class
power transistors that are ideally suited for high
reliability applications.
