IRVINE, Calif., Sept. 3, 2008 — Toshiba America
Electronic Components, Inc. (TAEC)* today announced
a family of 600V DTMOS II superjunction MOSFETs
that contribute to higher efficiency of switched-mode
power supplies, such as AC adapters in notebook and
desktop computers, servers, flat panel displays, and
ballasts used in lighting, due to lower on-state
resistance (R
characteristics. Developed by Toshiba Corp., the
DTMOS II MOSFETs employ a superjunction structure
that enables a reduction in both on-state resistance
(R
tradeoffs. Typically, when either of these
characteristics is reduced, the other increases, but with
its superjunction DTMOS II design, Toshiba has been
able to reduce both simultaneously, enabling higher
power efficiency and switching performance than
conventional MOSFETs.
In these devices, Toshiba refined the superjunction
structure with the company's second generation
DTMOS technology. By applying this design and
optimizing the entire device, Toshiba has achieved
figure of merit values for R
that are approximately 68 percent less than that of
conventional Toshiba MOSFETs. This figure of merit is
one important performance index for MOSFETs in
which smaller is better, and is indicative of higher
switching performance and power efficiency.
The first twelve products in the DTMOS II family include 12A, 15A, and 20A 600V MOSFETs, each offered
in a choice of four packages, including TO-3P(N), TO-220SIS, TO-220(W) and TFP, a compact surface
mount package. The 12A devices feature low on-resistance of 0.4 ohms ( Ω, max.), the 15A devices feature
on-resistance of 0.3 Ω (max.) and 20A devices have on-resistance rated at 0.19 Ω (max.).
"With a combination of low on-resistance, fast switching and ruggedness, our new DTMOS II devices are
ideally suited for the switched-mode power supply and ballast lighting markets and are expected to enable a
significant increase in power efficiency," said Jeff Lo, business development manager, Discrete Power
Devices, for TAEC.
