STMicroelectronics Introduces PowerMESH IGBTs for Switched-Mode Power SuppliesPatented device layout enables high frequency operation
Geneva / 08 Mar 2005
Geneva, March 8, 2005 — STMicroelectronics (NYSE: STM) has introduced a series of PowerMESH IGBTs that have been optimized for use in home appliance motor control, power factor correction and induction heating applications.
The V series IGBTs use a patented strip layout associated to a new carrier lifetime control. This improves the collector-emitter saturation voltage in the devices and also reduces switching losses. This makes the parts suitable for operation at up to 50 KHz.
The STGP20NC60V and STGW20NC60V are both 30A, 600V n-channel devices, available in a TO-220 or TO-247 package, respectively. The parts offer optimized Crss/Ciss ratio in order to avoid cross-conduction phenomena and low gate charge. Their switching losses include the tail current and the diode recovery energy.
The STGW20NC60VD is an equivalent part in a TO-247 package with a co-packaged freewheeling diode between the collector and emitter.
The STGW40NC60V is a 50A, 600V part in a TO-247 package. The STGY40NC60VD is a similar part, co-packaged in a Max247 package with an anti-parallel diode.
All the parts offer a 150°C maximum operating temperature and a low collector-emitter saturation voltage of less than 2.5V at their nominal operating currents. Prices range from US$1.25 to US$4.50 in quantities of 10,000 pieces.
