SSM9406GM
N-channel Enhancement-mode Power MOSFET
PRODUCT SUMMARY
BVDSS
30V
R DS(ON)
18mΩ
ID
9A
DESCRIPTION
The SSM9406GM acheives fast switching performance
with low gate charge without a complex drive circuit. It
is suitable for low voltage applications such as DC/DC
converters and general load-switching circuits.
The SSM9406GM is supplied in an RoHS-compliant
SO-8 package, which is widely used for medium power
commercial and industrial surface mount applications.
Pb-free; RoHS-compliant SO-8
