The SEPW series of LEDs provides a range of high-powered InGaN blue LEDs producing brilliant white light that can be used in general lighting applications, amusement and gaming equipment, and for backlighting TFT displays. Each module combines 8 LEDs in 2 separate channels. Modular design allows the SEPW devices to be easily assembled into string arrays by simply connecting the modules in series. The devices also provide superior color balance throughout the display because of the high density of LEDs that can be achieved. This also minimizes the distance that power and control lines must run between LEDs and from the LEDs to the control electronics. The white thermoplastic case is an innovative Sanken original design with exceptional heat dissipation properties. The white resin compound is especially formulated for superior reflectance and transmittance of the generated light. Enhanced thermal dissipation is achieved through the incorporated heatsink on the bottom of the package. The heatsink can be mated directly to an external radiator through the PCB for superior heat conduction allowing dense placement of modules. The leadframe is plated with silver, providing a highly-reflective surface for the bottom and sides of the emitting area. The terminals and heatsink are also silver-plated.
The SEPW Series from Sanken provides high‑efficiency multi‑chip white LED modules that combine eight LEDs in two channels. Designed for general lighting, display backlighting and gaming equipment, the modules feature a low thermal resistance (6 °C/W), silver‑plated leadframe, and a compact 13.7 mm × 5.23 mm footprint.
The datasheet includes electrical ratings, optical performance, mechanical dimensions, solder‑pad layout and safety guidelines. It also lists part numbers such as SEP8WL2001 (bulb light, 2900 K) and SEP8WN2001 (day white, 5000 K) and provides worldwide contact information for Sanken and Allegro MicroSystems.
