Description
D
Power MOSFETs from Silicon Standard provide the
designer with the best combination of fast switching,
ruggedized device design, low on-resistance and cost-effectiveness.
G
S
The SSM9620M is supplied in the SO-8 package, which is widely preferred
for commercial and industrial surface-mount applications. This device is well suited
for low voltage applications such as DC/DC converters.
