NPT

Non-punch through (NPT) IGBTs
Non-punch through (NPT) IGBTs serve as solid state switches for circuits that handle high voltages. Typical applications for these insulated-gate bipolar transistors include ac and dc motor drives, power supplies, and pulse generators for lasers and x-ray machines. Littelfuse makes standard (600–1200 V), high-voltage (1600–1700), and very high-voltage (2500–4000 V) NPT IGBTs. Each has a short-circuit withstand capability of 10 µs, and our very high-voltage NPT devices can replace multiple switches, rectifiers, and discharge relays with lower voltage ratings.
  • Typical saturation voltages of 2.4–4.0 V
  • Available with a wide range of typical current ratings, from 5.5 A to 150 A
  • Square reverse bias safe operating area (RBSOA)
  • Epoxy moldings have UL 94 flammability rating of V-0
  • Voltage-controlled metal oxide-semiconductor gates
  • Positive temperature coefficients make NPT IGBTs ideal for using in parallel
  • Square RBSOA improves inductive load clamping, which allows NPT IGBTs to handle hard switching without support from snubber diodes
  • Available in several packages—TO-268, TO-247, TO-263, and proprietary ISOPLUS i4-PakTM
  • High power densities
