Microsemi Corporation has introduced a new line of standard IGBT 3-phase bridge power modules in the compact SP3 package.

Designed for motor control applications, the new power modules feature a 3-Phase IGBT bridge using fast NPT IGBTs for 20 to 50 KHz high frequency applications and Trench Field Stop IGBTs for 5 to 20 KHz low frequency applications. All the new modules feature integrated sensors to monitor the module case temperature for over-temperature protection.

Current ratings are in the range of 30A to 50A for 600V and 15 to 25A for 1200V fast NPT IGBTs; and 20A to 75A for 600V and 25A to 35A for 1200V Trench Field Stop IGBTs.

With a very low 12mm profile and a small 40.8 mm x 73.4 mm footprint, the SP3 isolated package provides a very compact power solution. Their solderable terminals are easily mounted to a PCB. In addition to the main DC supply connections, these products offer extra DC supply pins to connect a decoupling capacitor. Combined with their very low parasitic internal inductance, this solution reduces over-voltage, minimizes noise, and improves operation safety.

While the new standard modules are designed for industrial applications, they are easily upgraded to withstand more severe environmental conditions, like those in aerospace

applications:
- Aluminium nitride substrate can replace standard alumina for improved thermal performance
- SiC diodes can replace FREDs for improved switching losses or increased operating frequency or temperature
- Aluminium Silicon Carbide (AlSiC) base plate can replace the standard copper base plate for reduced weight and extended lifetime against wide temperature cycles
- Packaging enhanced to withstand temperature ranges as low as -60°C
