It delivers high blocking voltage, excellent forward and reverse pulse current capability, and easy drive control, ensuring reliable and efficient operation.

 

With its robust design and superior performance, the XM30N18T2 is ideal for use in capacitor discharge units (CDUs), high-power pulse power supplies, and electronic fuses.

Product Introduction

 

 

The MCT (XM30N18T2) is a voltage-driven, compact, high-power, solid-state pulse switch. It features high blocking voltage, high forward and reverse pulse peak current capability, and simple operation. It can be used in applications such as capacitor discharge units, high-power pulse power supplies, and electronic fuses.

 

Operating Principle

 

An MCT is a thyristor based on MOSFET gate control. This MOSFET gate-controlled pulse power device combines the MOSFET and thyristor structures, utilizing the on/off behavior of the MOSFET to control the conduction and shutdown of the thyristor.

 

When the gate voltage is positive, the NMOSFET conducts, generating an electron current that flows into the N-drift region. This current serves as the thyristor's trigger current, turning the device on.

 

When the gate voltage is negative, the PMOSFET conducts, forming a hole conduction channel that short-circuits the PN junction between the N cathode region and the P-type base region. This draws the charge stored in the P-base region to the cathode, disrupting the positive feedback loop within the thyristor and turning the device off.
