The MCT is an MOS Controlled Thyristor designed for switching
currents on and off by negative and positive pulsed control of an
insulated MOS gate. It is designed for use in motor controls,
inverters, line switches, and other po wer s witching applications.
The MCT is especially suited for resonant (zero voltage or zero
current switching) applications. The SCR like forward drop
greatly reduces conduction power loss.
MCTs allow the control of high power circuits with very small
amounts of input energy. They feature the high peak current
capability common to SCR type thyristors, and operate at junction temperatures up to 150
Formerly developmental type TA49226.

Handling Precautions for MCTs
MOS Controlled Thyristors are susceptible to gate-insulation
damage by the electrostatic discharge of energy through the
devices. When handling these devices, care should be exercised to assure that the static charge built in the handler’s
body capacitance is not discharged through the device.
MCTs can be handled safely if the following basic precautions are taken:
1. Prior to assembly into a circuit, all leads should be kept
shorted together either by the use of metal shorting
springs or by the insertion into conductive material such
as “ECCOSORBD™ LD26” or equivalent.
2. When devices are removed by hand from their carriers,
the hand being used should be grounded by any suitable
means - for example, with a metallic wristband.
3. Tips of soldering irons should be grounded.
4. Devices should never be inserted into or removed from
circuits with power on.
5. Gate Voltage Rating - Never exceed the gate-voltage
rating of V
permanent damage to the oxide layer in the gate region.
6. Gate Termination - The gates of these devices are
essentially capacitors. Circuits that leave the gate opencircuited or floating should be avoided. These conditions
can result in turn-on of the device due to voltage buildup
on the input capacitor due to leakage currents or pickup.
7. Gate Protection - These devices do not have an internal
monolithic zener diode from gate to anode. If gate
protection is required an external zener is recommended.
