6.3A, 30V, 0.030 Ohm, Single N-Channel
LittleFET™ Power MOSFET
Features
• 6.3A, 30V
This Single N-Channel power MOSFET is manufactured
using an advanced MegaFET process. This process, which
uses feature sizes approaching those of LSI integrated
circuits, gives optimum utilization of silicon, resulting in
outstanding performance. It was designed for use in
applications such as switching regulators, switching
convertors, motor drivers, relay drivers, and low voltage bus
switches. This device can be operated directly from
integrated circuits.

Soldering Precautions
The soldering process creates a considerable thermal stress
on any semiconductor component. The melting temperature
of solder is higher than the maximum rated temperature of
the device. The amount of time the device is heated to a high
temperature should be minimized to assure device reliability.
Therefore, the following precautions should always be
observed in order to minimize the thermal stress to which the
devices are subjected.
1. Always preheat the device.
2. The delta temperature between the preheat and soldering
should always be less than 100oC. Failure to preheat the
device can result in excessive thermal stress which can
damage the device.
©2002 Fairchild Semiconductor Corporation
3. The maximum temperature gradient should be less than 5oC
per second when changing from preheating to soldering.
4. The peak temperature in the soldering process should be
at least 30 oC higher than the melting point of the solder
chosen.
5. The maximum soldering temperature and time must not
exceed 260oC for 10 seconds on the leads and case of
the device.
6. After soldering is complete, the device should be allowed
to cool naturally for at least three minutes, as forced
cooling will increase the temperature gradient and may
result in latent failure due to mechanical stress.
7. During cooling, mechanical stress or shock should be
avoided.
