Vce(Sus) Or V(Br)Ceo, And Iceo-Vce Measurement - Keysight Technologies B1505A Handbook

3-1-4. Vce(sus) or V(BR)ceo, and Iceo-Vce measurement

Measurement Parameters: Vce(sus) or V(BR)ceo
Application Test name: Ic-Vceo_R
Application Test setup name: (My Favorite Setup -> Example_AT): Ic-Vceo_R or Ic-
Device used in the example: MJL4281AG
Connection inside the N1259A Test Fixture: Use the figure shown in this section
Application description:
Measures Collector current vs. Collector-Emitter voltage and extracts Collector-
Emitter breakdown voltage (BVceo) and cut-off current (Iceo) at open base condi-
tion. The voltage drop by a resistor（0, 1k, 100 kΩ) inserted between the collector
terminal and the collector SMU can be compensated. A reminder message for assur-
ing the resister value is popped up just before starting the measurement.
Measurement is aborted just after the detection of the drain breakdown.
Connection inside the N1259A Test Fixture
For Vce(sus) or V(BR)ceo test, we have an option for inserting a 100 kΩ resistor
between the collector and the collector SMU as shown in figure 3-13. Two configu-
rations are shown as an example for no resistor (0 Ω selection) case and 100kΩ
resistor case.
NOTE: If measurement is made with Opt.300 Module Selector, use the procedure
shown in Appendix 2.

Use the following connection inside the N1259A test fixture
Open the N1259A test fixture cover, and connect the test leads shown in figure 3-2
by following the step numbers as shown in figure 3-11 and the following procedure
steps.
Note: The available colors of the leads are black and red only. The lead color used in
figure 3-11 is for reference only.
The numbers of the procedure steps correspond to the numbers on the drawing for
connecting the test leads.
