Product Overview
The EL_IR204C-A is an EVERLIGHT 3mm infrared emitting diode built with a GaAlAs chip and a water clear lens. The datasheet identifies the LED part number as IR204C-A and describes the package as a 3.0 mm infrared LED, T-1, with a 2.54 mm lead spacing for through-hole mounting.
At IF=20 mA and Ta=25°C, the device has a typical 940 nm peak wavelength, 45 nm typical spectral bandwidth, and 40 deg typical viewing angle. Radiant intensity is specified as 4.0 mW/sr minimum and 7.8 mW/sr typical at IF=20 mA, with higher pulsed typical values of 35 mW/sr at IF=100 mA and 390 mW/sr at IF=1 A under the stated pulse conditions.
Absolute maximum ratings include 100 mA continuous forward current, 1.0 A peak forward current for pulse width <=100 us and duty <=1%, 5 V reverse voltage, 150 mW power dissipation, and -40 to +85°C operating and storage temperature ranges. The soldering limit is 260°C for no more than 5 seconds.

Procurement Notes
When requesting a quote for EL_IR204C-A, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
