about 1000 You can choose from a wide range of products. We have a wide range of products from low voltage and low current products to high voltage and large current products.
Also, the type of package 1.0mm × 0.6mm from small size packages TO-220 There are many types of insertion types such as.
・Variety of types, including single, dual, complementary, and Darlington configurations

<high level of quality>
・Very low (<7 ppb) product defect rate
・There are many AEC-Q101 qualified products.

<Reliable supply>
・Global supply chain boasting one of the largest production bases in the industry

Therefore, you are sure to find a product with the desired specifications and the desired package.
Some product examples and package types are shown below. As you can see from the figure, various packages are available for each specification.

Next, the graph below compares the features of standard bipolar transistors, low Vce(sat) bipolar transistors, and MOSFETs.

Based on the above information, using a low Vce(sat) bipolar transistor rather than using a MOSFET can reduce losses and cost, so please refer to it.

When compared with the charging circuit shown in the figure below, using a low Vce(sat) bipolar transistor reduces power consumption and reduces the number of parts, resulting in lower cost and space savings in the PCB layout. can be converted.

There are many products with the same specifications but in packaging that are not introduced here, so please use Macnica Mouser when looking for a product.

schottky diode

In Schottky diodes, which feature a low Vf voltage, we have a wide range of products, mainly in small packages, depending on the current value.
We also have a lineup of products that feature low leakage current. You can select the most suitable product according to your specifications.
The figure below shows recommended small packages and specifications for low-voltage products.

The features and associated benefits of this small package product are listed below.

・Industry's top-class compact size → Saves board space
・Height 0. 18 mm → Thinner substrate
・Shortest heat path possible → Reduced power loss
・ low forward voltage drop Vf → Improved circuit efficiency
・Lead and halogen free → Environmentally friendly

We also have products with a withstand voltage of 100V or more and products with a current value of 10A or more.
If you want products with other packages or other electrical characteristics, please use Macnica Mouser.

Constant current regulator (CCR)

We will introduce a constant current regulator (CCR) as a product that supplies a constant current to an LED.
Place it in series with the LED (low side connection or high side connection) as shown in the lower left figure.
The lower right figure shows the relationship between input voltage and LED current when a resistor is used and when a constant current regulator (CCR) is used.

constant current regulator (CCR) features are as follows:

・Provides constant brightness over a wide input voltage range
・Low input voltage (Vin) and brighter LED
・ LED No binning required
・ EMI no occurrence of
・No thermal runaway due to negative temperature and voltage coefficients
・Easy mounting and few parts
・Power package products available (SOT223, SMB, SMC, DPAK, SOD-123)
・± Ten% current accuracy products available
・Fixed and adjustable current options

The lineup is as follows.
Please feel free to contact us if there is a desired product.

Fixed current products

current adjustable products
