DTA115GUA / DTA115GKA
Digital transistors (built-in resistor)
DTA115GUA / DTA115GKA
zFeatures
1) The built-in bias resistors consist of thin-film resistors
with complete isolation to allow positive biasing of the
input, and parasitic effects are almost completely
eliminated.
2) Only the on / off conditions need to be set
for operation, making device design easy.
3) Higher mounting densities can be achieved.
