Small and Medium Diodes
Recently, many products ranging from computers and home appliances to automobiles and industrial
equipment have been driving the need for effective solutions to reduce size and weight.
Semiconductor requirements differ from application to application. Take power supplies for example,
which are being required to accommodate higher capacity in smaller dimensions. This increases the
temperature at which systems are operated.
To meet these requirements, Toshiba offers an extensive portfolio of small, high-efficiency diodes,
including Schottky barrier diodes (SBDs) featuring high-speed operation and low forward loss.
Diodes
Schottky Barrier Diodes (SBDs)
Toshiba offers low-loss SBDs fabricated with a next-generation process. These SBDs
will help increase the performance of equipment that requires a small form factor and
high efficiency, such as mobile devices and switching power supplies.
SBDs with a reverse voltage of 20 V to 60 V and an average forward current of 0.7 A
to 5 A are available in small surface-mount packages. You will find SBDs that best suit
your applications.
Rectifier Diodes
General-Purpose Rectifiers and reverse-current protection
Super-Fast-Recovery Diodes (S-FRDs)
High-Efficiency Diodes (HEDs)
Diodes with a reverse voltage of 200 V to 1000 V and an average forward current of
0.5 A to 3 A are available in small surface-mount packages. Toshiba’s product portfolio
also includes diodes with high ESD performance ideal for automotive applications.
Zener Diodes
Zener diodes are available with a wide range of Zener voltage specifications from
6.2 V to 82 V. They can be used for a wide range of applications such as consumer,
automotive and industrial electronics.

Internal Structure of FLAT Packages
The FLAT packages have a lead clamp structure to reduce wire inductance and
resistance and improve heat dissipation performance. Without a conventional
wirebonded structure, these packages provide a higher surge capability.

Schottky Barrier Diodes (SBDs)
Schottky barrier diodes (SBDs) have a junction formed between a semiconductor and a metal such as molybdenum, instead of a PN
junction. Unlike PN junction diodes, SBDs are majority carrier devices. Therefore, SBDs feature low forward voltage and short reverse
recovery time, making them ideal for high-speed switching applications.
Toshiba offers SBDs fabricated using a new process that provides an improved V

RRM
trade-off. These new SBDs, together with
conventional SBDs, will meet diverse design requirements.
Schottky-Barrier Diodes (SBDs) with Improved Trade-Off
Toshiba now offers small to medium SBDs fabricated with a new process.
Owing to low peak forward voltage (V
FM
) and low repetitive peak reverse
current (I
RRM
) characteristics, these SBDs provide low power loss and
thus help reduce the size and improve the power efficiency of mobile
handsets, switching power supplies, etc.
