Description

High-Power Infrared (IR) LEDs

Overview

High Power IR LED is a high-power light-emitting diode that emits infrared light. It is usually made of semiconductor materials and can produce high-intensity, high-brightness infrared light. High-power infrared LEDs are mainly used in infrared communications, infrared sensors, infrared lighting and other fields.
Available at 850 nm (visible faint red glow, high camera sensitivity) and 940 nm (completely covert), delivering radiant flux up to 2000 mW per emitter.
Optimized for high-drive operation with excellent thermal dissipation for stable performance in demanding environments.

Absolute Maximum Ratings

Parameter	Symbol	Rating	Unit
Continuous Forward Current	I_F	800	mA
Peak Forward Current (≤100 μs, Duty ≤1%)	I_FP	1200	mA
Reverse Voltage	V_R	5	V
Power Dissipation	P_D	3000	mW
Junction Temperature	T_j	150	°C
Operating Temperature	T_OPR	−40 to +85	°C
Storage Temperature	T_STG	−40 to +100	°C
ESD Withstand Voltage (HBM)	—	≥2000	V

Note: Soldering temperature: 260°C ±10°C for 5 seconds max.

Key Applications

Long-Range Surveillance: High-intensity IR illumination for PTZ cameras, license plate recognition (LPR), and perimeter security (up to 200+ meters)
Industrial Machine Vision: Structured lighting for 3D scanning, defect detection, and robotic guidance

ℹ️ APPLICATION NOTE:
• Mount on metal-core PCB or aluminum heatsink to maintain T_j < 125°C.
• Use constant-current drivers with soft-start to prevent current surge.
• 850 nm offers ~30% higher camera response than 940 nm but emits faint red glow.
• For arrays, ensure uniform thermal design to avoid hotspot-induced lumen depreciation.
