Product Overview
The EL_ALS-PT19-315C-L177-TR8_V8 is an EVERLIGHT ambient light phototransistor sensor classified under the LED category. It uses a light-to-current analog output and is specified for external conversion with Vout = IPH x RL, allowing the sensed photocurrent to be translated into a voltage through a load resistor.
The device is supplied in a miniature SMD package measuring 1.7 mm x 0.8 mm x 0.6 mm with ±0.1 mm package tolerance. Recommended operation covers a 2.5-5.5 V supply range and -40 to +85 °C temperature range, while absolute maximum supply voltage is -0.5 to 6.0 V.
Optical and electrical parameters include a 390-700 nm sensitivity range, typical 630 nm peak sensitivity wavelength, typical 3.5 photocurrent ratio for IPH3/IPH2, and specified light-current values under fluorescent and incandescent illuminants. Assembly guidance includes a 260 °C reflow peak profile, up to three reflow cycles, and manual soldering limits below 350 °C for less than 3 seconds per terminal.
