Toshiba Electronics launches new compact, integrated IGBT technology for induction heating
Toshiba Electronics Europe has expanded its family of compact, integrated IGBTs with a high-speed switching device that will simplify the design and reduce the component count in cooking appliances and other induction heating applications. Optimised for voltage resonance inverter switching, the new 1200V N-channel, ‘enhancement mode’ GT40QR21 comprises an IGBT and a reverse recovery freewheeling diode monolithically integrated into a single, compact device.
MaxiToshiba’s GT40QR21 is designed for very high speed switching – typical IGBT fall time (tf) and turn-off time (toff) with a collector current of 40A are just 0.2µs and 0.4µs respectively, while typical reverse recovery time (trr) for the freewheeling diode is 0.6µs (IF = 15A). Typical collector-emitter saturation voltage (VCE(sat)) is rated at just 1.9V (IC = 40A).
Supplied in a TO-3P(N), TO247-equivalent package the IGBT has dimensions of 15.5mm x 20.0mm x 4.5mm and a maximum junction-to-case thermal resistance (Rth(j-c)) of 0.65ºC/W.
