SSM9971GM
Dual N-channel Enhancement-mode Power MOSFETs
PRODUCT SUMMARY
BVDSS
60V
R DS(ON)
50mΩ
ID
5A
DESCRIPTION
The SSM9971GM 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 SSM2310GM is supplied in an RoHS-compliant
SO-8 package, which is widely used for medium power
commercial and industrial surface mount applications.
