characteristics, ON resistance of drain_source, and

trans conductance (gm)

It shows examples of measurement which obtains each parameter of ON resistance of

drain_source and trans conductance (gm) of N-channel FET under the same conditions as

Section 4.1.3.1 " I

characteristics."

The diagram on the right in this frame shows
the measurement result of the trans
conductance (gm) of a FET based on the
extracts from the FET performance table
below. ON resistance of drain_source is
described in measurement step (6).

In addition, extracts from the performance

table of device characteristics which should
be investigated in advance and the
connection diagram indicating how to
connect a measured device to the attached
test adapter are shown.

trans conductance (gm) of FET

Caution!

When starting or finishing measurement, operate CS-3000 as shown below:



When starting measurement, set HIGH VOLTAGE breaker to DISABLED and open the test fixture.



After connecting a measured device, set HIGH VOLTAGE breaker to ENABLED.



After finishing measurement, rotate VARIABLE counterclockwise to set the value to 0% (to discharge
applied voltage).



Set HIGH VOLTAGE breaker to DISABLED.

Connection diagram

Connect the drain/gate/source terminals of a FET
to the collector/base/emitter terminals of the test
adapter. For connection between the test fixture
and CS-3000, see Section 3.3.2.
