STMicroelectronics Introduces New Diode to Simplify Headlamp Design

22 June 2000

Low VCEsat and gate charge, high-reliability and DPAK form factor characterize 3A, 600V IGBT

    GENEVA - STMicroelectronics today made available to power-circuit designers a highly reliable 3A, 600V IGBT (insulated gate bipolar transistor) that combines extremely low on-voltage drop (VCEsat ), low gate charge and integrated freewheeling diode in a compact DPAK form factor.

    The STGD3NB60SD is particularly suitable for cutting the cost of high-efficiency, high-intensity gas discharge lamps for the automotive market. The device is also appealing for motor control and other low-power (about 100W) bridge applications operating at frequencies of less than 1kHz.

    With a typical VCEsat of 1.1V at 3A and total gate charge of 18nC, characteristics it inherits from its 'S' family legacy and PowerMESH(TM) layout, the N-channel STGD3NB60SD offers exceptional efficiency. Moreover, its integrated freewheeling (antiparallel) diode, afforded by the IGBT's double die assembly and virtually unique for an IGBT, saves space and cost. Further space savings accrue from the STGD3NB60SD's compact surface-mount DPAK (TO-252) package.

    ST's proven PowerMESH layout uses an optimized epitaxial process, patented strip layout and high-efficiency Single Implanted Planar Structure (SIPS) edge termination. `S' family IGBTs devices are optimized to achieve minimum on-voltage drop for frequencies under 1kHz. The device is available on tape and reel for automated assembly.
