Application Notes
To continue testing, perform the following procedures.
Procedure 9: V
To measure the V
1. Set Left-Right Terminal Jack Selector to correspond with
2. Increase Variable Collector Supply Voltage until current
Note: Model 370 current is limited. Set to 400 mA. Check for
1.1 V MAX.
3. To measure V
Procedure 10: V
To measure the V
1. Set Polarity to (–).
2. Repeat Procedure 8 to measure V
Diacs
Diacs are voltage breakdown switches used to trigger-on triacs
and non-sensitive SCRs in phase control circuits.
Note: Diacs are bi-directional devices and can be connected in
either direction.
To connect the diac:
1. Connect one side of the diac to the Collector Terminal (C).
2. Connect other side of the diac to the Emitter Terminal (E).
To begin testing, perform the following procedures.
Procedure 1: Curve Tracer Setup
To set the curve tracer and begin testing:
1. Set Variable Collector Supply Voltage Range to 75 Max
2. Set Horizontal knob to sufficient scale to allow viewing of

3. Set Vertical knob to 50 µA/DIV.
4. Set Polarity to AC.
5. Set Mode to Norm.
6. Set Power Dissipation to 0.5 W. (0.4 W on 370)
7. Set Terminal Selector to Emitter Grounded-Open Base.
