TLPGE125

The TLPGE125 is a kind of LED lamp. It is designed for panel circuit indicator. There are some features as follows: (1) 3.0 mm diameter (T1-3/4); (2)InGaAlP PURE GREEN LED; (3)all plastic mold type; (4)colorless clear lens; (5)low drive current, high intensity red light emission: recommended forward current, IF=15 to 20 mA (DC); (6)all plastic molded lens, provides an excellent ON-OFF contrast ratio; (7)fast response time, capable of pulse operation; (8)high power luminous intensity; (9)applications: suitable for outdoor message signboard, safety equipment, etc.

The following is about the maximum ratings (Ta=25) of TLPGE125: (1)forward current (DC), IF: 50 mA; (2)reverse voltage, VR: 4 V; (3)power dissipation, PD: 140 mW; (4)operating temperature range, Topr: -30 to 85; (5)storage temperature range, Tstg: -40 to 120.

The last one is about the electric and optical characteristics (Ta=25) of TLPGE125: (1)forward voltage, VF: 2.27 V typ and 2.8 V max at IF=20 mA; (2)reverse current, IR: 50A max at VR=4 V; (3)luminous intensity, IV: 47.6 mcd min and 150 mcd typ at IF=20 mA; (4)peak emission wavelength, P: 562 nm typ at IF=20 mA; (5)spectral line half width, : 11 nm typ at IF=20 mA; (6)dominant wavelength, d: 558 nm typ at IF=20 mA.
