Page 4: Testing Power Semiconductors
CAUTION * * * * * * * The part to be tested must be Isolated & De-energized! Connecting the tester to live equipment will damage the tester. This equipment operates at voltages as high as 6400V. Under no circumstances should the equipment EVER be operated without using the 3 wire line cord, plugged into a properly grounded outlet. -

Page 6: Overview Of Testing Procedures
OPERATING INSTRUCTIONS *** CAUTION : UP TO 6400V ON TEST LEADS *** INTRODUCTION This Power Semiconductor Tester is designed to perform testing of power semiconductors, such as, SCRs/Thyristors, Diodes, IGBTs, Transistors, and most MOS FETs. The Cathode (Emitter) of the device under test is operated near ground potential. The tester performs three tests : PFV (Peak Forward Voltage), PRV (Peak Reverse Voltage), and Gate Voltage and Current to trigger (Base Current for Transistors). - Page 7 SCRs (THYRISTORS) Make sure the Voltage Control is at the zero position (fully counter clock-wise) before turning the unit on. Connect the Anode, Gate and Cathode leads to the device to be tested. DO NOT MIX UP THE ANODE AND CATHODE LEADS OR HIGH VOLTAGE WILL BE APPLIED TO THE GATE! Place the function switch in the PRV position and press the “TEST”...

Page 8: Testing Set-Up And Procedures
TESTING SET-UP AND PROCEDURES PRESSURE PACK (Hockey Puck) SCRs (Thyristors) Make sure the Voltage Control is at the zero position (fully counter clockwise) before turning the unit on. Connect the Anode, Gate and Cathode leads to the device to be tested. DO NOT MIX UP THE ANODE AND CATHODE LEADS OR HIGH VOLTAGE WILL BE APPLIED TO THE GATE! Place the function switch in the PRV position and press the “TEST”... -
Page 9: Pressure Pack Diodes
PRESSURE PACK (Hockey Puck) Diodes Make sure the Voltage Control is at the zero position (fully counter clockwise) before turning the unit on. Connect the Anode and Cathode leads to the device to be tested. NOTE : Diodes only have to be tested in one direction. If the diode is forward biased (standard), the function switch should be in the PRV position. -
Page 10: Gtos (Gate Turn-Off Thyristor)
GTOs (Gate Turn Off Thyristors) Make sure the Voltage Control is at the zero position (fully counter clock- wise) before turning the unit on. Connect the Anode, Gate and Cathode leads to the device to be tested. DO NOT MIX UP THE ANODE AND CATHODE LEADS OR HIGH VOLTAGE WILL BE APPLIED TO THE GATE! Place the function switch in the PRV position and press the “TEST”... -
Page 11: Power Modules
POWER MODULES Power Modules comes in a variety of configurations and sizes. The testing procedures described below illus- trates the the set-up for a Dual Thyristor Bridge. The principle is the same for Thyristor/Diode, Diode/Diode, and single Diode or Thyristor Modules. Make sure the Voltage Control is at the zero position (fully counter clockwise) before turning the unit on. -
Page 12: Transistor Modules (Igbts And Darlingtons)
Transistor Modules (IGBTs and Darlingtons) • Connect test lead between the Ground Plate of the component and the GROUND terminal on the tester. • Connect a 100k ohm Resistor between the BASE and EMITTER terminals on the tester. • Do Not Mix Up the COLLECTOR and EMITTER Leads or HIGH VOLTAGE will be Applied to the BASE! -
Page 13: Diode Modules For Rotating Rectifiers
Diode Modules for Rotating Rectifiers Make sure the Voltage Control is at the zero position (fully counter clockwise) before turning the unit on. Connect the Anode and Cathode leads to the diode to be tested. NOTE : Diodes only have to be tested in one direction. If the diode is forward biased (standard), the function switch should be in the PRV position. -
