Fifth-Generation Deep Trench Process Super Junction MOSFETs

Toshiba's 600 V and 650 V DTMOS V process delivers compact MOSFETs that enable simplified design-in and reduced EMI noise in power switching applications

Image of Toshiba's Fifth Generation Deep Trench Process Super Junction MOSFETsToshiba introduces the next generation of super junction (SJ) deep trench semiconductor technology for high-efficient power MOSFETs. Devices based on the new DTMOS V process operate with lower EMI noise and reduced on resistance (RDS(ON)) compared to previous DTMOS IV MOSFETs.

As with the previous DTMOS IV semiconductor technology, DTMOS V is based on a single epitaxial process involving ‘deep trench etching’ followed by P-type epitaxial growth. The deep trench filling process results in a narrowing of cell pitch and a lowering of RDS(ON) when compared with more conventional planar processes. Toshiba’s deep trench process allows an improved thermal coefficient of RDS(ON) compared to conventional super junction MOSFETs using multi-epitaxial growth process.

With DTMOS V, Toshiba has been able to reduce RDS(ON) of the DPAK TK290P60Y by up to 17% compared with the lowest RDS(ON) available from the TK12P60W DTMOS IV MOSFET. The company has also further optimized the trade-off between switching performance and EMI noise.

DTMOS V MOSFETs simplify the design and improve the performance of power conversion applications, including switching power supplies, power factor correction (PFC) designs, LED lighting, and other AC/DC applications. The first MOSFETs based on the fifth-generation process offer ratings of 600 V and 650 V and are supplied in DPAK (TO-252) and TO-220SIS (smart isolation) packaging. Maximum ON resistance ratings range from just 0.29 Ω to 0.56 Ω.
