Power Rectifiers
The rectifier is a unidirectional device which conducts when for-
ward voltage (above 0.7 V) is applied.
To connect the rectifier:
1. Connect Anode to Collector Terminal (C).
2. Connect Cathode to Emitter Terminal (E).
To begin testing, perform the following procedures.
Procedure 1: V
To measure the V
1. Set Variable Collector Supply Voltage Range to 1500 V.
2. Set Horizontal knob to sufficient scale to allow viewing of
3. Set Mode to Leakage.
4. Set Vertical knob to 100 µA/DIV. (Due to leakage setting, the
5. Set Terminal Selector to Emitter Grounded-Open Base.
6. Set Polarity to (–).
7. Set Power Dissipation to 2.2 W. (2 W on 370)
8. Set Left-Right Terminal Jack Selector to correspond with
9. Increase Variable Collector Supply Voltage to the rated
Procedure 2: V

A Kelvin test fixture is required for this test. If a Kelvin fixture is
not used, an error in measurement of VFM will result due to
voltage drop in fixture. If a Kelvin fixture is not available,
