International Rectifier IRGB4059: 600V IGBTs reduce power dissipation
Mar 7 2008 12:45PM | Permalink |Comments (0) |
Targeting use with devices having 20-kHz switching and low short-circuit requirements, the 600V IRGB4059 IGBT (insulated-gate-bipolar-transistor) family reduces power dissipation by as much as 30%, according to the vendor. This reduction allows high-efficiency power conversion in UPS (uninterruptible-power-supply) and solar-inverter applications. With ultrafast soft-recovery diodes, the family provides lower collector-to-emitter saturation voltage and total switching energies than punch-through and non-punch-through IGBTs. The device also features internal ultrafast soft-recovery diodes improving efficiently and reducing EMI. The IRGB4059 IGBTs cost 68 cents.
