SnapLED 75 and SnapLED 150 are dual-mode binned making it easy to choose the right
automotive signal product. Designers and consumers can count on SnapLED for color stability
in rear combination lamps, front turn signals, and high mount stop lamp applications. The SnapLED
package utilizes Philips Lumileds’ pioneering Solderless Clinch technology, designed specifically to
meet the automotive industry’s need for extreme reliability. The Solderless Clinch technology
uses a formable metal substrate which offers ease of manufacturing, styling flexibility, and thermal
conductivity unmatched by other LED assemblies. The efficient optical design, high-brightness
material, and high-current capability reduces the number of LEDs required for lighting functions
and lowers the total cost and engineering complexity. SnapLED products meet SAE/ECE/JIS
automotive color requirements and are AEC-Q101C qualified. SnapLED emitters are used for:
•
Rear Combination Lamps
•
Front Turn Signal Lamps
•
High Mount Stop Lamps
•
Mirror Turn
•
Rear Fog Lamp

Dual Product Binning
Automotive lamp makers can now take advantage of Philips Lumileds flux stability across a wide operating range with SnapLED 75 and SnapLED
150 dual binning. The dual binnned products are designated with an “88” in the part number. SnapLED emitters are optimized and binned for use
in dual-mode drive current applications such as automotive stop and tail lights, car and truck marker-turn, and tail-turn applications using low-cost,
high-reliability resistor-diode drive circuits.
The optimized dual binned emitters offer 100% flux stabilization at temperature, allowing the user to operate the LEDs with flux & color stability
over a dynamic range of forward voltages: SnapLED 75 from 75 mA–2.5 mA and SnapLED 150 from 150 mA–5 mA. This industry leading feature
enables plug and play, immediate use of the SnapLED products without the need for additional handling, treatment or further characterization.
Key features include:
- Flexible dual binning scheme
- Higher maximum junction temperature of 135ºC
- Higher flux at high & low currents
- Consistent color at high current
- Forward voltage bins with high current spacing of 60mV and with low current spacing of 30mV
- 20% flux bins at both high and low current with a guaranteed flux ratio between high and low current.
100% of the SnapLED 75 and SnapLED 150 products have 5 character binning eliminating the need to segregate parts between single and dual mode
applications. Dual binning simplifies the production process, and ensures light output and color consistency over a wide operating range.

Reliability Testing
Philips Lumileds conducts extensive reliability stress testing before the introduction of new products to ensure that they meet the reliability
expectations of the automotive market. The development of SnapLED includes reliability test simulations for both high voltage (24V) jump start and
high voltage (18V) alternator failure conditions to ensure LED survivability, performance and quality integrity as well as design margin allowance.
