・2-terminal (single) Zener Diodes

A wide variety of packages is available – beginning with

the world’s f irst 0603 sized (GMD2) package – in

abundant quantities for use in consumer, manufacturing,

and automotive applications.

Utilization of a proprietary device structure results in

ultra-low capacitance (Typ: 1pF) – ideal for ESD surge

protection on high-speed communications lines, including

USB2.0.

・Low-capacitance Zener Diodes

RSB series Bi-Directional Zener diodes absorb forward

and backward surges in signal lines of all types, from

mobile phones, PCs and other consumer devices to

automotive products, all in a single package that’s ideal

for high-density mounting.

・Bi-Directional Zener Diodes

・Schottky Barrier Diodes　RSX series

The RSX series utilizes proprietary precision processingand device technologies for low VF and IR.ROHM products command a significant share of themarket – a testament to their high-efficiency, low-loss,high-reliability design.

The RB series is by far the most widely used and mass

produced Schottky Barrier Diode series for consumer

electronics as well as industrial and automotive applications.

Both surface mount and axial packages are available.

ROHM offers wide variety range of products from GMD2 to

TO220.

Generally, there is a trade-off between VF (Forward Voltage) and IR (Reverse Current). ROHM’s RSX series, however, feature simultaneously low VF and IR by utilizing proprietary precisionprocesses and device configuration.

Conventional Schottky Barrier Diodes possess weaker ESD resistance than even PN junction diodes. ROHM’s RSX series, on the other hand, features greater resistance to ESD than competitor productsdue to utilization of precision processes and device configuration.

The compact VMN2 package reduces mounting area (package power=100mW, the same as the VMD2). In addition, unlike the bottom surface electrode configuration of competitor products, the flat lead construction makes it easy to automatically verify thesolder condition.

Optimization of device conditions has enabled low VF and low IR.

Device optimization ensures high ESD and IFSM tolerance.

ROHM offers a broad lineup of high-density single-, dual-, and triple-element models that contribute to end-product miniaturization.

ROHM offers a 1A class product in the TUMD2 package (1913 size, t=0.6mm). In addition, arear-surface heat sink boosts package powerup to 0.5W (compared with 0.2W for same sizedunits).

The PMDU (2616 size) and PMDT (3826 size) package types are well-suited for thin portable devices.

Optimization of device conditions has enabledlow VF and low IR.

Device optimization ensures high ESD.
