IN-S63BT5UW

Summary

every figure cited to the datasheet below

0603 top-view SMD LED in a diffused-lens ('U' lens code), PCB-type moulded package — 1.6 × 0.8 × 0.6 mm^{p.1, p.9}
InGaN white emitter — no dominant wavelength; specified by CIE chromaticity x = 0.27 / y = 0.255 at the 5 mA test current^{p.3, p.8}
Chromaticity binned for white — a full CIE bin table, codes Z1–Z5, A1–A8, B1–B8, C1–C8, D1–D8, E1–E4, AE–AG^p.4
The '5' in the part number is Inolux's test-current code — this variant is specified and tested at 5 mA, not the series' default 20 mA ((Blank) = 20 mA, 5 = 5 mA)^{p.9, p.3}
Forward voltage 2.8 V typ at the 5 mA test current^p.3
Luminous intensity 320 mcd typ at 5 mA, through the diffused lens over a 120° viewing angle (2θ_1/2)^{p.3, p.8}
25 mA max continuous forward current; 100 mA peak at 1/10 duty, 0.1 ms pulse; 5 V max reverse voltage; 75 mW max dissipation^p.2
Operating −30 to +85 °C, storage −40 to +90 °C^p.2
Moisture sensitive and ESD sensitive (InGaN) — ships dry-packed in a sealed moisture-barrier anti-static bag^{p.2, p.12}
Supplied on tape and reel, 4000 pcs per reel (EIA-481-1A conductive black carrier tape)^{p.10, p.11}

IN-S63BT5UW is the white member of Inolux's IN-S63BT series, a low-profile 0603 top-view indicator LED, and the one variant with a diffused lens — the 'U' in the part number is the lens code.^p.9 The '5' is the Current field of the same numbering scheme: this variant is specified and tested at 5 mA rather than the series' usual 20 mA.^p.9 The die is InGaN, and being white there is no dominant wavelength: the colour is specified as CIE chromaticity x = 0.27 / y = 0.255^p.3 and binned across a full CIE table (codes Z1–Z5 through AE–AG).^p.4

At the 5 mA test point it drops 2.8 V typ and returns 320 mcd^p.3 — a lot of light for a quarter of the usual current. Do not read that 2.8 V as a 20 mA figure: every guaranteed number in the electrical table for this part is a 5 mA number.^p.3 From a 5 V rail, (5 − 2.8) / 0.005 = 440 Ω lands it on its test point; the datasheet asks for a current-limiting resistor explicitly.^p.13

The absolute maximums still allow 25 mA continuous and 100 mA pulsed (1/10 duty, 0.1 ms),^p.2 but above 5 mA you are off the characterized map. The diffused lens plus 120° viewing angle^p.3 make it a soft, wide source rather than a spot. Reverse voltage is rated to only 5 V,^p.2 and InGaN chips are static-sensitive devices — ESD precautions apply in design and assembly.^p.2
