Thyristor Schematic symbol
Thyristor

Thyristor: A bi-stable semiconductor device that comprises three or more junctions and can be switched between conducting and non-conducting status.
Bi-directional diode thyristor: A two terminal thyristor having substantially the same switching behavior in the first and third quadrants of the principal voltage-current characteristic.
Bi-directional triode thyristor: An n-gate or p-gate thyristor having substantially the same switching behavior in the first and third quadrants of the principal voltage-current characteristic.
N-gate thyristor. A three-terminal thyristor in which the gate terminal is connected to the n-region adjacent to the region to which the anode terminal is connected and that is normally switched to the on-state by applying a negative signal between gate and anode terminals.
P-gate thyristor. A three-terminal thyristor in which the gate terminal is connected to the p-region adjacent to the region to which the cathode terminal is connected and that is normally switched to the on-state by applying a positive signal between gate and cathode terminals.

How to Measure Operational Life.
This circuit shows an example used to test the operation life of a 2N1870 thyristor.
The only purpose of the circuit is to show a possible setup to run the thyristor.
Component values are provided, but only as an example, no other description is provided.

The Device Under Test [DUT] is the 2N1870 semiconductor. Note the use of the three meters in the circuit above. Although the age of this schematic is not relevant, you can tell its age of the use of 60cps [Cycles Per Second] instead of Hz.
Diodes D1 and D2 appear to be normal signal diodes. The three meters are simple meters M2 is set up to read DC mA, M1 and M3 are set up to read peak or RMS voltages.
The operational life test should be performed in the test circuit shown to the left, or its equivalent. Transformer T1 is adjusted such that the peak value of secondary voltage from T3 equals the rated forward blocking voltage of the device under test. Transformer T2 is adjusted such that meter reads 220 mA average rectified current. Transformer T5 is selected to provide a maximum secondary peak voltage of 5 volts as read on meter M3. The device under test shall be in an oven at an ambient temperature of +100C +/-5C.
