Part Number : 30G122, GT30G122
Function : IGBT / 400V, 120A, Transistor
Package : TO-220 Type
Manufacturers : Toshiba
This is 400V, 120A, IGBT. The IGBT is insulated-gate bipolar transistor.
IGBTs combine the MOSFET advantage of high input impedance with the bipolar transistor advantage of high-voltage drive. The conductivity modulation characteristics of a bipolar transistor make it ideal for load control applications that require high breakdown voltage and high current. Toshiba offers a family of fast switching IGBTs, which are low in carrier injection and recombination in carrier.
The Toshiba discrete IGBTs are available in high-voltage and high-current ratings. They are used in inverter and power conversion circuits for such diverse applications as motor drivers, uninterruptible power supply (UPS) systems, IH cookers, plasma display panels (PDPs), strobe flashes and so on.
Features of the Toshiba Discrete IGBTs :
(1) IGBTs also featuring fast switching
(2) Low collector-emitter saturation voltage even in the large current area
(3) IGBTs featuring a built-in diode with optimal characteristics tailored to specific applications
(4) High input impedance allows voltage drives
(5) Available in a variety of packages
30G122 Datasheet PDF
Prior to the development of IGBTs, power MOSFETs were used for power amplifier applications which require high input impedance and fast switching. However, at high voltages, the on-state resistance rapidly increases as the breakdown voltage increases. It is thus difficult to improve the conduction loss of power MOSFETs.
On the other hand, the IGBT structure consists of a PNP bipolar transistor and a collector contact made on the p+ layer. The IGBT has a low on-state voltage drop due to conductivity modulation. The following figure shows the VCE(sat) curve of a soft-switching 900-V IGBT. Toshiba has offered IGBTs featuring fast switching by using carrier lifetime control techniques. Now, Toshiba offers even faster IGBTs with optimized carrier injection into the collector Player. In the future, Toshiba will launch IGBTs with varied characteristics optimized for high-current-conduction and high-frequency-switching applications. The improvements in IGBTs will be spurred by optimized wafers, smaller pattern geometries and improved carrier lifetime control techniques.
