Constant Current Diode "CRD S Series (SMD Type)"

Constant Current Diode "CRD S Series (SMD Type)"

Low mounting height with resin package products! Ideal for LEDs too!

The CRD S series is a resin-sealed SMD package product for surface mounting. It has a lower mounting height than standard packages, allowing for the installation of thin LEDs without obstructing light. Additionally, we have added the "S-223T (22mA)" for high-brightness LEDs. Previously, the series had an upper limit of "S-183T (18mA)," which required multiple units for 20mA high-brightness LEDs, but with the "S-223T (22mA)," it is now possible to supply a constant current with a single component.

Constant current diode "CRD E series (axial lead type)"

Constant current diode "CRD E series (axial lead type)"

High reliability with airtight sealing!

The "CRD E Series" uses components that provide stable constant current characteristics in a compact size. It is a small device that employs a DO-35 style DHD (Double Heatsink Diode) structure with a DO35 (300mW) package. With hermetic sealing, it offers high reliability, and the materials used are inexpensive and suitable for mass production. Previously, the series had a maximum of "E-153 (15mA)," but now "E-183 (18mA)" has been added. This allows for the supply of a constant current that does not exceed the rated current, making it possible to stabilize the brightness of high-brightness LEDs rated at 20mA with a single component.

Constant Current Diode (CRD) E Series

Constant Current Diode (CRD) E Series

Ideal for constant current supply for LED brightness stabilization!

A constant current diode (hereafter referred to as CRD: Current Regulative Diode) is a diode that, as its name suggests, can supply a constant current even when the voltage fluctuates. It is a component that can continuously provide a constant current across a wide voltage range from low voltages below 1V to high voltages up to 100V. It can supply a constant current to the load regardless of variations in the applied voltage, changes in load resistance, or ripple voltage. Generally, constant current circuits are complex and require multiple components. Additionally, the design is not straightforward, but a CRD can easily achieve constant current characteristics with just one component.

Constant Current Diode (CRD) S Series

Constant Current Diode (CRD) S Series

Even with voltage fluctuations, a constant current can be supplied! Ultra-low price diode!

A constant current diode (hereafter referred to as CRD: Current Regulative Diode) is a diode that can supply a constant current even when the voltage fluctuates, as its name suggests. It is a component that can continuously provide a constant current over a wide voltage range, from low voltages below 1V to high voltages up to 100V. It can supply a constant current to the load regardless of fluctuations in the applied voltage, changes in load resistance, or ripple voltage.
