Application Notes
Procedure 11: I
For these steps, it is again necessary to connect the Trigger to
MT2 through a 10
same.
To measure the I
1. Set Power Dissipation to 50 W.
2. Set Max Peak Volts to 75 V. (80 V on 370)
3. Set Mode to DC.
4. Set Horizontal knob to 5 V/DIV.
5. Set Vertical knob to approximately 10% of the maximum I
6. Set Terminal Selector to Emitter Grounded-Open Base.
Procedure 12: I
To measure the I
1. Set Polarity to (+).
2. Set Left-Right Terminal Jack Selector to correspond with
3. Increase Variable Collector Supply Voltage to maximum
4. Decrease Variable Collector Supply Voltage to the point
Procedure 13: I
To measure the I
1. Set Polarity to (–).
2. Continue testing per Procedure 12 for measuring I

the beginning point of the line, just before the line changes to
a dot, represents the I

Sidacs
The sidac is a bidirectional voltage-triggered switch. Upon appli-
cation of a voltage exceeding the sidac breakover voltage point,
the sidac switches on through a negative resistance region (simi-
lar to a diac) to a low on-state voltage. Conduction continues until
current is interrupted or drops below minimum required holding
current.
To connect the sidac:
1. Connect MT1 to the Emitter Terminal (E).
2. Connect MT2 to the Collector Terminal (C).
To begin testing, perform the following procedures.
Procedure 1: (+) V
Note: The (+) and (-) symbols are used to designate the polarity
of MT2 with reference to MT1.
To measure the (+)V
1. Set Variable Collector Supply Voltage Range to 1500 Max
2. Set Horizontal knob to 50 V/DIV.
3. Set Mode to Leakage.
4. Set Polarity to (+).
5. Set Power Dissipation to 2.2 W. (2 W on 370)
6. Set Terminal Selector to Emitter Grounded-Open Base.
7. Set Vertical knob to 50 µA/DIV. (Due to leakage mode, the
