Product Overview
EL_SIR204C is an EVERLIGHT 3mm infrared emitting LED identified in the device selection guide as SIR204C. It uses GaAlAs chip material with a water-clear lens and is supplied in a 3.0 mm T-1 through-hole package with 2.54 mm lead spacing. Package dimensions are specified with ±0.25 mm tolerance unless otherwise specified.
Electrical and optical data are given at Ta=25°C. At IF=20 mA, the device has 875 nm typical peak wavelength, 80 nm typical spectral bandwidth, 1.3 V typical and 1.6 V maximum forward voltage, and 4.0 mW/sr minimum to 6.4 mW/sr typical radiant intensity. Under pulsed drive conditions of pulse width ≤100 us and duty ≤1%, radiant intensity is 30 mW/sr typical at IF=100 mA and 300 mW/sr typical at IF=1 A.
Assembly and operating limits include 150 mW power dissipation at or below 25°C free air temperature, 260°C soldering temperature for ≤5 seconds, -40 to +85°C operating temperature, and -40 to +100°C storage temperature. The part remains within RoHS compliant version, complies with EU REACH, and meets the listed halogen-free limits.

Procurement Notes
When requesting a quote for EL_SIR204C, 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.
