ISL70024SEH, ISL73024SEH
200V, 7.5A Enhancement Mode GaN Power Transistor
The ISL70024SEH and ISL73024SEH are 200V
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.

▪ ISL70024SEH radiation acceptance (see TID
report)
GaN’s exceptionally high electron mobility and low
temperature coefficient allows for very low r
,
• High dose rate (50-300rad(Si)/s): 100krad(Si)
• Low dose rate (0.01rad(Si)/s): 75krad(Si)

higher switching frequency with more efficiency while
reducing the overall solution size.
• Low dose rate (0.01rad(Si)/s): 75krad(Si)
▪ Ultra small hermetically sealed 4 Ld Surface Mount
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.
