Overview The ECN 3053/3054 is a MOS (Metal Oxide Semiconductor Field Effect Transistor), IGBT (Insulated Gate Bipolar Transistor) and other three-phase bridge drive IC. Particularly, it is possible to change the three-phase induction motor of AC200 ~ 230V system, the DC brushless motor It is optimal for speed control. The difference between ECN 3053 and ECN 3054 is the presence or absence of an operation (3053: Yes, 3054: No) and pin assignment only. Figure 1 shows the basic block of the system configuration. 30A class IGBTs or MOSs can be driven, and the output of up to 2.2kW class. The three-phase motor can be controlled at variable speed.
INTRODUCTION There are two types of Field-Effect Transistors, the Junction Field-Effect Transistor (JFET) and the “Metal-Oxide Semiconductor” Field-Effect Transistor (MOSFET), or Insulated-Gate Field-Effect Transistor (IGFET). The principles on which these devices operate (current controlled by an electric Field) are very similar — the primary difference being in the methods by which the control element is made. This difference, however, results in a considerable difference in device characteristics and necessitates variances in circuit design, which are discussed in this note.
The G series is the standard Metal Oxide varistor series from UCC/NCC. These MOVs are available in a wide variety of voltages and sizes, which will make them ideal in most applications where a surge protector is needed.
The G series is also ideal because of the variety of UL and CSA approvals. The varistors with a 5mm or 7.5mm lead spacing are available with ammo pack taping. Refer to the Mini -Glossary at the end of the Metal Oxide varistors section for additional technical information and specifications.

The CP Series of transient voltage surge suppressors are Metal-Oxide varistors (MOVs) of tubular construction. These varistors are intended for mounting within a multipin connector assembly. This series is available in a wide range of voltage ratings from 6V to 150V VM(AC)RMS. Their internal dimensions allow them to be used with 16, 20, or 22 gauge connector pins. The unique coaxial mounting arrangement of these tubular varistors allow them to become part of a transmission line itself. Added inductive lead Effects are eliminated.
Features • Unique Coaxial Design and Mounting Arrangement in Tubular Form • Designed to be Integrated Within Standard Connector Assemblies • Wide Operating Voltage Range VM(AC)RMS . . . . 6V to 150V • Can be Used with 16, 20, or 22 Gauge Standard Connector Pins • No Derating up to 125°C Ambient
Zenamic voltage suppressors are Metal Oxide varistors having a non-linear current-voltage characteristic which exhibits and almost constant voltage over a wide range of current. They are ideally suited to all transient voltage protection applications and their high clamping ratios and low steady state power consumption offer considerable circuit advantages over more traditional methods of protection.
INTRODUCTION These Metal Oxide Resistors offer excellent performance in applications where stability and uniformity of characteristics are desired. They provide lower cost alternatives to Carbon Composition Resistors and General Purpose Metal Films. Metal Oxides also can replace many low power General Purpose wirewound applications, saving both money and time, with shorter delivery cycles. The normal style & the miniature style of RSF series are coated with layers of gray and pink colors flame-proof lacquer respectively.
