The leading company in diodes, we serve customers' wide-ranging needs,
from AC input section bridge diodes to secondary-side rectifier section
We carry a full assortment from small- to large-capacitance.
Our diodes are distinguished by their high durability, high reliability and ultra-low loss, thanks to our unique design, process and production technologies.
General rectifying diodes are high-voltage PN-junction rectifying elements.
Our chip structure stands out for its heat and humidity resistance, using our own chemically and physically stable glass passivation.
The voltage goes up to 800 V and output currents range from 1 A to 25 A.
Our bridge diodes are suited for rectifying commercial power.
Their voltage goes up to 1600 V, with 0.9 V forward voltage.
We have a full line with output currents from 0.4 A to 50 A, high-voltage, high-IFSM, and low-noise in every package.
These diodes use the barriers created from the junction of metal
They make optimal high-speed, low-VF diodes,with lower forward startup voltage than a PN junction and extremely fast switching.
These are high-voltage, high-speed PN-junction rectifying elements
with improved reverse recovery characteristics.
They are perfectly suited for SMPSes in fields including home electronics as well as those for offices and factories. With switching frequencies around 100 kHz,they are responsive to the trend towards higher frequencies in SMPSes.
Our experience as a power semiconductor manufacturer is utilized in our MOSFETs. Their low input capacitance and high durability make them ideal for use in SMPSes.
The thyristor, in its normal state, will block an applied voltage in either direction; but when an appropriate current pulse is applied to the gate electrode, current will flow through anode to cathode thus turning on the power to the load circuit.The thyristor has a planar passivation.We have the thyristor of the general reverse-blocking type and the thyristor of the type without the reverse voltage.The thyristor of the type without the reverse voltage is suitable for an inrush current limiting circuit.
We have a bountiful lineup of surge absorbers, for protection against lightning, excess voltage, and ESD.
Power Zeners are voltage clamp surge protection elements applying the avalanche breakdown phenomenon in the reverse direction from the PN junction. They have greater surge current capacities than ordinary Zener diodes. We also have power clampers, specially developed for SMPS circuit snubbers, with power diodes and high-speed diodes built into one package.
Our ICs for power management make great use of high-voltage BCDMOS processes. They answer needs for improved power consumption efficiency.
With a broad lineup of high-voltage, high-current stepping motor driver ICs for various drive systems and high-output interface driver ICs for actuator drive, we respond to the growing performance of devices and the diversification of needs.
These are non-insulating DC-DC converter power ICs. By combining the main components for a DC/DC converter into one package, we have eliminated the headaches of power circuit design. We have two types of rectifying systems: the SBD rectification type and the highly efficient synchronous rectification type. Realize high-performance power circuits easily by selecting the products that fit the application.
These are IC modules for quasi-resonant power supplies, containing control
circuits and main switching elements.
With just a few external components, construct a partial resonance power
supply that saves energy in standby.
The MS1003SH and MS1004SH consume less power in standby mode than conventional ICs.
The ICs incorporate various functions to make it more user-friendly and to make it easier to design a power supply with fewer external components.
MCZ Series are an advanced symmetric LLC current resonant mode controller for Bridge Converter.
Symmetric LLC resonant converter application is expanding widely due to its extremely high efficiency and low noise characteristics.
MH2501SC (master IC) and MH2511SC (slave IC) comprise ICs for a current-critical interleaved PFC circuit.
Interleaving with master and slave ICs ensures low noise and high efficiency, which are characteristics of current-critical PFCs, even in high power range.
One-phase PFC can be configured using just the master IC.
MV Series feature functions specialized for LED lighting, such as no auxiliary winding quasi-resonant operation, deep dimming and compatibility with illuminated light switches.
And an off width modulation function allows for smooth deep dimming of 1% or less.
