Toshiba Announces Next-Generation Superjunction Technology for Power MOSFETs

May 8, 2012

New Process in Latest 600V MOSFETs Delivers Ultra-Low RDS(ON), Reduced Switching Losses and Fewer Incidents of 'Ringing''

SJ MOSFETs

IRVINE, Calif., — Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced its DTMOS-IV process, a new-generation of superjunction (SJ) technology for power MOSFETs. Products based on the DTMOS-IV technology will make ideal switching devices in switch mode power supplies, lighting ballasts and other power applications that demand a combination of high-speed operation, high-efficiency and low EMI noise.

SJ MOSFETs offer ultra-low on resistance without power loss penalties. As a result, Toshiba's new DTMOS-IV process, which is being deployed in the company's latest family of high-speed, high-efficiency 600V power MOSFETs, offers on resistance ratings that are up to 30 percent lower than third-generation DTMOS products for the same die size. The benefit is that designers can now choose a 600V MOSFET in a TO-220SIS package with an RDS(ON) of just 0.065Ω, or a similar device in a TO-3P(N) package with an RDS(ON) down to 0.04Ω.

In addition to driving down on resistance, DTMOS-IV has also allowed Toshiba to minimize MOSFET output capacitance (Coss) for optimized Switching Power Supply operation at light load. Furthermore, an optimized gate-drain capacitance (Cgd) delivers improved dv/dt switching control, while an optimized RDS(ON) *Qg figure of merit supports high-efficiency switching. Finally, by supporting lower dv/dt ratings, DTMOS-IV also reduces EMI noise in high-speed switching circuitry.

The DTMOS-IV technology uses a deep-trench process that results in a narrowing of the lateral SJ pitch, leading to optimized overall performance.

Toshiba's first MOSFETs based on the DTMOS-IV process are available now in an expanded line-up that includes: DPAK, IPAK, D2PAK, I2PAK, TO-220, TO-220SIS, TO-247, TO-3P(N), and TO-3P(L) packages.
